3 The art of handling air Good air is a factor in your quality of life. Whether outside in the open air or in an enclosed space, we only feel truly well in the fresh air. Air, the elixir of life, lets us breathe freely. It is invigorating, inspiring, and gives us the energy to live and work. TROX understands the art of competently handling air like no other company. In close collaboration with demanding customers from around the globe, we have successfully manufactured leading technologies and marketed systems and components for indoor ventilation and air conditioning. We are consistently expanding upon this position by means of intensive research and development activities. Heinz Trox The individual is the focus at TROX: as a customer with visionary ideas and technological goals: as a motivated and qualified company employee, as a responsible decision-maker at the management level and, last but not least, as a human being who would like to live and work in well-ventilated spaces. Since our corporation was founded, we have stood by this philosophy and vouched for our good name. Indicative of our solution-minded approach, it has created our distinctive customer base and thus become the source of our company s success. Headquarters Neukirchen-Vluyn, Germany On the following pages, we would like to introduce TROX and its extensive product range. Please, take us at our word by challenging us with ambitious tasks and placing trust in our competency and customer oriented thinking! Share the experience: The art of handling air! Heinz Trox 1

4 The individual is the deciding factor The individual remains the deciding factor in all that TROX undertakes. The individual, by virtue of his or her visions, wishes, needs, abilities, and knowlege, defines the goals that TROX pursues carefully and deliberately. TROX is an owner-led company with horizontal hierarchies in which the individual has decisionmaking powers. Consistency, reliability, and a mature feeling of responsibility for customers, employees and the environment have been the pillars of the TROX GROUP company politics for decades. It is the customers of TROX that decide how the company will act on their behalf. They set goals based upon their well-being as well as their architectural and technological visions, and TROX in turn assists them in realising those goals. The customer-oriented corporate leadership has made TROX what it is today: a world-wide and effective partner for those demanding ventilation and air conditioning solutions for all types of buildings. Each and every employee contributes to the success of the company in that they earn the customers trust with their motivation and competence, and then they confirm that trust day after day. The targeted training and continued education of our employees, as well as their lasting job satisfaction, are thus important concerns of TROX management. 2

5 In a small space of 110 square metres at his living quarters in Neukirchen-Vluyn, Heinrich Trox began the production of diffusers together with his brother Friedrich in Within a few years, this garage start-up became a successful medium-sized company, which is still family-owned today.

6 A tradition of innovation The history of the company began with an innovation: the specialisation in components for ventilation technology. In the air conditioning industry, which was still quite young in 1951, this was a revolutionary decision. Trailblazing inventions have since marked the rise of the company to the leading position in marketing and technology. Innovations themselves are tradition with TROX. The company holds over 200 patents and registered designs in ventilation and air conditioning technology. The systematic research and development of the individual product groups enjoys increasing expansion based on project-related development contracts. With its customer-specific solutions, TROX sets an innovating standard and, with that in mind, continues to enter new and lucrative markets and maintain sustainable business opportunities. As a result, TROX, since the introduction of the first ceiling induction diffusers in the 1980s, has been the leading supplier of these multifaceted products in Europe.

A human being can live without food for over a month and without water for about a week, but without air a person can survive no more than three to five minutes at the most. And we need a lot of air to live! While we are quite adequately supplied with two litres of water per day, we breathe around 20,000 litres of air each day. In a poorly ventilated room, the air is quickly used up. The concentration of carbon dioxide mounts rapidly. The results are fatigue and decreased performance. 11

29 Combination diffusers Combination diffusers Modern office buildings, which may for example have low energy requirements thanks to use of concrete core cooling, require small air exchange rates on the one hand, whilst providing very little room for installing the ventilation on the other. In such situations, installing combination diffusers into walls as a mixed or displacement flow system is a compact and cost-efficient complete solution. Grafenberger Höfe office park, Düsseldorf, Germany Types VSD 35-3-AZ QLW-AZ Air is discharged and extracted through a single element in the wall. The optional cross-talk sound attenuator effectively suppresses the transmission of sounds from room to room.

Rectangular; available in various frame widths 90 9,000 m 3 /h L: 200 1,225 mm H: mm Types DGVAR DGSELF These grilles blow warm supply air downward and cold air up ward. They regulate the direction of the airstream either automatically without an auxiliary power or by means of an electric actuator. In industrial construction, they can also be installed into circular ducts. Rectangular 50 1,900 m 3 /h L: mm H: mm 28

31 Displacement flow diffusers Displacement flow diffusers Displacement flow diffusers allow cooled fresh air to be discharged into rooms at very low air velocity and close to the floor so that a pool of fresh air forms over the floor. This prevents air turbulence and thus drafts. The air rises when it reaches sources of heat such as people or computers, transferring the heat and the used air to the ceiling. The fresh air quality in the areas occupied by people thus remains at the same especially high level while maintaining a pleasant set temperature. Displacement flow diffusers can also be integrated into wall areas or as columns in a room to save space. They are made of galvanised and powder-coated sheet steel and available in a variety of constructions. Airport, Hamburg, Germany Type QLV The multi-cornered design of this displacement flow diffuser is unique. It is available in a 90 model for corner installation, a 180 model for wall installation and a 360 model as a freestanding column. 90 /180 / ,200 m 3 /h mm H: 500 1,750 mm Types QLE QLF These two types are notable for their flat, space-saving construction and, with a sloped front panel (QLF), for their elegant design. Rectangular 40 3,700 m 3 /h L: 300 1,500 mm H: 150 2,000 mm Individual displacement flow diffusers The many shapes and models offer convenient solutions with a wide variety of applications.

Circular; rectangular m 3 /h 725 mm 600/625 mm Type DUK AJA These two compact jet nozzles are inconspicuous and are used to discharge air for long distances in the room. They can be adjusted electrically or manually and work in heating or cooling modes. Circular 70 5,000 m 3 /h mm (DUK), mm (AJA) Powerful output, great comfort In large rooms such as exhibition halls or airport terminals, providing the desired comfort is always a technical challenge. High flow rates have to be distributed into the room in such a way that the visitors always have a fresh atmosphere without draughts independent of the number of people and the current outdoor temperature. TROX masters this challenge mainly using cleverly positioned jet nozzles that can blow fresh air into the room without draughts. Barajas Airport, Madrid, Spain 32

35 Human beings are one of the biggest sources of humidity indoors. We lose half a litre of water into the environment each day through our skin alone. Too much humidity makes us feel unwell and minimises our ability to work. At room temperatures of C, the body radiates about 20 35% of its excess heat by evaporating sweat on the skin s surface. As the temperature rises, our sweat production increases as well, and our cardiac and circulatory problems worsen. At relative humidity levels of % and temperatures above 25 C, we feel that the air is sticky and oppressive, and our ability to work well falls to a minimum. 33

Ingenhoven Overdiek Architekten GmbH & Co. KG Imtech Deutschland GmbH & Co. KG 1,800 underfloor induction diffusers (BID) In view of the pending climatic change and increasing energy costs, the EIB has been aiming for environmental certification for the eva luation of the ecological qualities of the new building from the beginning. The result was particularly high requirements on the environmental compatibility of the ventilation technology used. At the same time, the most demanding requirements on further criteria such as air quality, comfort, noise level, flexibility, spatial requirements, maintenance-friendliness, and costs were to be met. Thanks to the early involvement of TROX engineers, an extremely economical ventilation concept consisting of 1,800 underfloor induction diffusers (BID) was realised. Integrated unnoticeably into the rooms architecture, these underfloor induction diffusers enable the use of economical air-water systems, even in room-high glazed buildings. The decision to use TROX underfloor induction diffusers paid off. The new EIB building was the first building on continental Europe to be evaluated as Very Good according to the particularly comprehensive BREEAM environmental certification method. 34

37 Individual system design COMBEAM : Air-water systems that can do it all Air-water systems use heat exchangers to cool and/or heat indoor air by means of water-based heat exchangers. The system saves energy because it takes less power to transport heat away in water than in air. Air-water systems can be installed in open or suspended ceilings and are very well suited for refurbishment projects. We differentiate between active and passive chilled beams. COMBEAM or multi-service chilled beams, the multifunctional air-water systems from TROX, not only provide the normal heating, cooling and ventilation functions, but can also be equipped with extra building services, enabling space-saving integration of lighting, smoke detectors, loudspeakers and sprinkler systems. COMBEAMs can also be designed in the form of design elements to accentuate a building s architecture, for example, as ceiling sails or as inconspicuous ceiling installations. The option of smooth integration into centralised building communication and control systems is also possible. Advantages for installation and refurbishment Shortened construction period thanks to integral prefabrication Easy installation (plug-and-play) Significant reduction in interfaces Reduction in ceiling void height Reduced investment costs Faster return on investment Advantages in operation Energy savings Low maintenance and operating costs Flexibility for changes of use Type MDF multi-functional ceiling sail, installed in the Chambre de Commerce of Luxembourg, designed by Claude Vasconi and Jean Petit Motion detector Smoke detector Sprinkler 35

38 Air-water systems Active air-water systems Active air-water systems In the case of active air-water systems, fresh air is supplied to rooms from the central plant in addition to water cooling. In comparison to pure air systems, the fresh air volume required for a person s well-being can be reduced to one-third. Because the system is based on the principle of induction, no extra fans are necessary to transport the air, thus saving energy and reducing noise to an absolute minimum. Active air-water systems are mostly called active chilled beams. These systems save space because they allow you to reduce the size of the central plant systems and supply ducts, and their in stallation height is very low. They are operationally reliable and low-maintenance because they do not contain any moving parts. They run in both cooling and heating mode, which means you do not need to install extra static heaters. Constitution Center, Washington DC, USA Types DID312 DID300B DID600B DID600B-L These active chilled beams are available with optional integrated lighting and extract air systems. Their supply air discharge is comparable to that of the slot diffuser. Active chilled beams can be installed parallel or at 90 degrees to the façade. The DID300 can also be operated under wet coil conditions.

41 When the air is too dry, it can make you ill. In winter, heating frequently makes the air far too dry. This often results in sore throats, sinus infections and susceptibility to colds. About one-third of all sick days are taken due to illnesses affecting the respiratory passages. Good indoor air quality, ensuring optimum good health, not only keeps employees fit but pays off for employers, too. 39

42 Decentralised ventilation systems More flexibility in new construction due to decentralised ventilation The Laimer Würfel building in Munich, Germany In the Laim quarter of Munich near the downtown area, the Laimer Würfel (Cube of Laim) is a contemporary office building characterised by its efficient use of space and individuality. The building has eleven upper floors with about 1,900 m 2 gross floor area and a multifunctional circular floor, which also has a convention area and casino in addition to shops. Large plant rooms inside the building and branched, space-consuming air duct works are made superfluous by the use of decentralised façade ventilation units, thus increasing useful floor space. The decentralised ventilation units of TROX/FSL are also designed to save energy and be maintenance friendly, whereby the operating costs are minimised. Project: Laimer Würfel, Munich, Germany Owner: HOCHTIEF Projektentwicklung Architect: FRICK KRÜGER NUSSER PLAN 2 Specialist planer J. Weißenhorn - CAE - H. König Ventilation solution: Decentralised sill units for supply and extract air, as well as secondary air units (FSL-B-ZAB) At an early construction stage, 1,600 frames were integrated into the outer façade. 800 frames were equipped with decentralised ventilation units. They filter the supply air, provide for, ventilation, and heat recovery, and heat or cool. To achieve the required heating and cooling capacities, 540 additional frames were equipped with secondary air units that can heat or cool the indoor air during pure secondary air operation. The other 260 frames casings act as a reserve and are initially only equipped with insulation boxes for noise and heat insulation. They can later be retrofitted with TROX/FSL ventilation units. The frame type of construction makes it possible to react to changes in use in the office building in an fast, cost-effective manner. 40

43 Individual system design More individuality with minimised investment and energy costs In our decentralised façade system ventilation (FSL) solution, we integrate sound-absorbing ventilation units into a building s exterior. These units can be installed under sills or into walls or false floors. They discharge fresh air into rooms and/or exhaust air out along the shortest possible route. Both in construction and in retrofitting, TROX decentralised, individually controllable ventilation systems offer a rich variety of design options for ventilating a building. Clients can install a complete decentralised ventilation system or combine the decentralised supply air system with a central extract air system. The product variation ranges from simple flow devices to complex systems with heating and cooling functions and integrated individual room regulation (FSL-CONTROL). Decentralised ventilation systems provide numerous advantages. Individual users can adjust the air quality and room temperature in their rooms according to their own individual tastes. For investors, TROX systems are economical, energy-saving and, above all, flexible solutions that can be re-adapted at any time with very little work to suit change of use. In developing decentralised ventilation units, TROX takes its inspiration from the inventiveness and design resourcefulness of architects to find solutions in which functionality and design merge into an ideal whole. With our cost-efficient prefabrication of façade elements, TROX provides investors with integral construction, reduced installation times and reduced interfaces.

44 Decentralised ventilation systems Individual system design Creative solutions for the refurbishment of existing buildings Office complex in Frankfurt am Main, Germany Existing standard solutions in ventilation technology can often not be used for the refurbishment of existing buildings. Here, companies that can make state-of-the-art technology usable in traditional architecture with creativity and flexibility are in demand. In this area, TROX/FSL has been able to prove its capabilities, especially during the refurbishment of an office complex in Frankfurt. For the refurbishment of the air conditioning system of Feldbergstraße 35, a building in which the German representative of the British National Westminster Bank AG has its headquarters, TROX developed a special ventilation solution between the sill and the ceiling together with the building owners and architect. Project: Office complex, Frankfurt/Main, Germany Owner: CB Richard/Ellis Investors Architect: Collignon Architektur Specialist consultant: INTEG Dipl.-Ing. Georg Mayer & Partner HVAC-contractor: KLU Klima-Lüftungs-Umwelttechnik KG Ventilation Façade-integrated sill ventilation solution: units with supply and secondary air functions (FSL-B-ZUS) The spatial conditions and usage plans required a ventilation concept that could make do without a horizontal air distribution system. Only in this way could the setup of combination and open-plan offices continue to be possible. In the research and development laboratory of TROX/FSL, extensive flow tests were performed to meet the project requirements. The advantage in the use of decentralised units was that no suspended ceilings were required for ducts. The high flexibility through the single room control and user-adapted settlement possibilities were an additional advantage. Further examples for the decentralised sill ventilation solutions of TROX/FSL are the Imtech Haus in Hamburg, the Laimer Würfel in Munich, and the Lighttower in Frankfurt/Main.

45 Individual system design Decentralised ventilation - a clever refurbishment alternative Complex refurbishment projects confront planners of the technical building equipment with sophisticated problems. Here, a special focus is on optimum, modern air conditioning and ventilation technology. In the process, decentralised ventilation units are increasingly forming the starting point for innovative solutions since they offer great freedom for design and fulfil modern usage requirements. A decisive advantage lies in the lack of duct work. Decentralised ventilation units are installed near or into the outer façade so that the ventilation of the stories takes place directly via the outer façade. This leads to short transport distances with low pressure losses. At the same time, the façade becomes an active component that can assume further air conditioning functions. Through the preassembly of individual components or complete, multi functional façade modules at the manufacturer s factory, the assembly and installation work on-site is strongly reduced. If the user is not present, the units switch to standby mode or they are switched off. The energy required for operation can be determined simply so that the energy costs can be settled based on consumption. This motivates the users to use energy more sparingly since they can actively sink their individual operating costs in this manner. Water as an energy-carrying medium FSL units dissipate thermal loads using an air-water heat exchanger. Water as an energy-carrying medium has a high specific heating capacity and lower specific volume than air. In comparison with a given air flow rate, the same thermal load can be dissipated as with a lower water rate flow. As a result, the cross-sections of the transport lines can be reduced. This and the elimination of the duct works can considerably reduce the transport energy expended. Bürkleinhaus, Munich, Germany Supplementary air conditioning systems In many indoor climate concepts, ventilation systems are supplemented by additional systems to achieve high and better comfort. Chilled ceilings, for example, are particularly well suited for dissipating higher thermal loads. INSIDE OUTSIDE Façade ventilation solutions 43

Type RM-0-3-D The smoke detector has extensive self-monitoring (dirt contamination, electronics) and must only be maintained once a year. The application depends on the direction of air flow. Permissible air velocity is 1 to 20 m/s. 50

53 More than 80 % of the deaths that occur in fires are due to smoke poisoning. In the toxic smoke, people lose consciousness after only two to three breaths. Our lungs cannot withstand much, especially in conjunction with high temperatures; they start to become damaged at 65 C. In nine out of ten cases, fires undergo a relatively long initial smoldering phase in which they produce a great deal of smoke but relatively little heat. 10 kg of foam, for example, will produce a volume of flue and fire gases of 25,000 m 3. Intact, well-coordinated fire safety systems and modern building communication and control systems will detect fires early, prevent smoke from spreading within the building and exhaust the flue gas. 51

KG Schiffsbau-/Dockbautechnik Ventilation solution: Volume flow controllers (RN;EN), various air terminal devices, like grilles, ceiling diffusers (DLQ, ADLR), jet nozzles (DUK), and slot diffusers (VSD 35) More than 80% of the fully air-conditioned cabins have a balcony. Wellness areas, spa landscapes, exquisite restaurants, and stages provide for the well-being and entertainment of the passengers. A ship places other demands on indoor ventilation and air conditioning technology than a building. When the Solstice class luxury liners sail the seven seas at 24 knots in every wind and weather and set anchor in all climatic zones, the passengers on board should always enjoy a consistently pleasant climate. For this reason, among other things, particularly flexible volume flow control is needed. TROX has solved this task very well with air terminal units of the Type RN, RN stainless steel, and EN. In addition to the required flexibility, TROX was also able to reduce the power consumption of the air conditioning and ventilation system considerably.

55 System-powered air terminal units System-powered air terminal units This type of controller eliminates conventional balancing dampers and thus the time-consuming and expensive work of balancing and adjusting the flow rates in the building. With Types RN and EN controllers, the desired flow rate can be simply adjusted manually using the scale located on the outside of the unit. These air terminal units were designed for constant flow rates but are also available with motorised flow rate adjustment. The casing and the damper blade are made of galvanised sheet steel. In the case of the Type VFC, the damper blade is made of plastic. The controllers are generally maintenance free. The plastic Type VFL volume flow limiter is easy to insert into circular ducts. It limits the flow rate to the set value and maintains it at a constant level within a close tolerances when changes in pressure occur. Nuremberg Fairgrounds, Nuremberg, Germany Type RN This air terminal unit for circular ducts can, for instance, be used in front of air terminal devices.

External louvres provide good protection to keep rain, leaves, and birds from getting into the supply and exhaust openings of ventilation systems. Pressure relief dampers and non-return dampers are used to isolate individual sections in ventilation systems. When the fan is running, the blades open; the degree of opening depends on the air velocity through the unit. When the fan is switched off, the blades close automatically. Combinations of external louvres and multileaf dampers or pressure relief dampers have a dual function in supply and exhaust openings of ventilation systems. They keep rain, leaves and birds from getting in, but also restrict or isolate the air flow during ventilation system downtime. Pressure relief dampers close automatically when a malfunction leads to excessive pressure differences in duct works. Types AK AKK TDK These circular dampers have many applications. They are available with manual or motorised adjustment. Shut-off dampers are made of coated steel or plastic.

60 Sound attenuators Oasis of peace on Red Square The Ritz-Carlton in Moscow, Russia The exclusive Ritz-Carlton luxury hotel lies in the direct vicinity of Red Square on Tverskaya Street, the main boulevard of Moscow. The rooftop terrace on the twelfth floor provides a unique view of the Kremlin, Red Square, St. Basil s Cathedral, and the Cathedral of Christ the Saviour. With its 334 spacious rooms and suites, the magnificent building was built in the Imperial Russian style and offers its guests an exquisite, incomparably comfortable ambience. Inside, select materials like marble and fine woods were used. Project: Ritz Carlton Hotel, Moscow, Russia Owner: Hotel Consulting & Development Architect: Andrei Meerson Investor: Red Square Development Company Specialist consultant:polimeks LIMITED LIABILITY COMPANY HVAC-consultant: POLIMEKS LIMITED LIABILITY COMPANY Ventilation Attenuators and splitters solution: (various MSA and MKA type), air terminal units (TVZD), such as grilles (ASL), ceiling diffusers (DLQ), slot diffusers (VSD), and jet nozzles (DUK-V) High demands were placed on the air conditioning system, especially in regard to comfort and noise protection. In the middle of the hectic Russian capital, the hotel should be an oasis of peace and comfort. For this project, TROX developed an energy-saving, noise-insulating ventilation and air conditioning concept. TROX Types MSA 100 and MSA 200 splitter attenuators and Types MKA 100 and MKA 200 splitters were used. With their profiled splitter frames that aid flow, the latter reduce the pressure drops in comparison with conventional splitters by up to 30%, which makes high energy savings possible in system operation. The splitters are hygienically tested according to VDI This guarantees that the materials used are generally recognized as safe and do not provide a breeding ground for microorganisms. 58

61 Splitters Splitter attenuators Circular silencers Attenuators In ventilation systems, noise stems from a variety of components such as fans, air terminal units, or fire dampers. To comply with a specified noise level, attenuators are added to suitable locations in the ventilation system. The attenuators should have adequate silencing capabilities and low air resistance, as well as being as small as possible. With the introduction of VDI 6022, specific hygiene requirements for air conditioning systems have bee set up for the first time. Splitters and splitter attenuators from TROX are certified for use in air conditioning systems in accordance with VDI 6022 Parts 1 and 3, DIN 1946 Part 4, and VDI Types MKA XKA With respect to conventional splitters, the aerodynamically formed splitter frames reduce pressure drops by up to 30% and thus the system operating costs. As an alternative, designs can be in stainless steel or coated splitters. Type MKA provides a higher level of sound attenuation, particularly in the area of critical fan noise levels. Type XKA is well suited for silencing higher frequencies (e.g. in cases of machine noise). The splitter frame is made of galvanised steel. Rectangular; square L: 500 1,500 mm W: 100/200/300 mm H: 300 1,800 mm Other dimensions upon request. Types MSA XSA Attenuators consist of rectangular casings with built-in splitters of Types MKA/XKA.

62 Filters Not just clean, but pure Clean room production of Frank Plastic AG in Waldachtal, Germany Project: Filter solution: Frank Plastic AG, Waldachtal, Germany High-efficiency filters ceiling-mounted, high-efficiency filters wall-mounted, pharmacy clean room diffusers On 40 injection moulding machines in a 2,000 m 2 clean room of the class 8/D, Frank Plastic AG produces high-quality, medical-technical products, such as pump units for water jet surgery. In the process, very high demands are placed on the air purity and sterility of the entire production process. To achieve the necessary air quality, TROX highefficiency terminal filters of filter grade H14 were installed as ceiling and wall diffusers. The air terminal devices have a tight fit test device and a measuring point to monitor the differential operating pressure. In addition, special pharmacy clean room diffusers provide for sterile air conditions at individual workstations and in particular manufacturing zones. Air filtration The objective of air filtration is to use appropriate filter media and units to establish and maintain the level of cleanliness required for indoor spaces. Air filtration is the most important procedure in a ventilation system, particularly in the case of clean room technology. Air filters in the form of fibre filters are used in various engineering areas. In air conditioning systems they are used as so-called standard air filters for removing coarse and fine dust out of the air, thus simultaneously protecting downstream equipment and system components. In clean room technology (e.g. in the pharmaceutical, medical, and microelectronics industries, etc.), systems require an additional particulate air filter to guarantee the high clean room classes required and to act as air equalisers for laminar flows. The following types of filters can be differentiated: Coarse particle filters as filter pads for automatic roll filters, as cut-to-size pads, and as cardboard frame filters for cell air filters and rolls. Z-Line filters/ filter cells. Bag filters made of high-quality, chemical, synthetic or glass fibre media for cell frames in the standard market sizes. Minipleat filters as high-performance filters for extracting fine dust, suspended particles and aerosols. Particulate filter cells for areas with the strictest standards for air purity and hygiene. High-performance filter panels for clean room technology. 60

63 Filter units Filter units Air filters remove contaminants such as dust, microbes and pollen out of the air. A variety of filter housings are available for the different installation situations, as part of a centralised air handling unit or for separate air filtering, for instance, of a contaminated, closed-off area. Filters are used both in ventilation systems for office buildings and for air filtering in production processes that create a lot of dust, as well as in sensitive areas such as microbe-free operating theatres or clean rooms in the pharmaceutical and microelectronic industries. Particulate air filter Universal casings for duct installation These universal casings are used as primary and secondary filter levels in air handling systems. They can hold coarse, fine, and particulate air filters, as well as activated carbon filters. 1,700 approx. 54,000 m 3 /h depending on the filter type as an individual system Duct particulate filters for highly sensitive areas Duct particulate filters are used in areas with the highest air purity requirements, such as in the chemical and pharmaceutical industries or in both hospital and clean room technology. They can be installed as individual units for varying air flow rates or as a combination of up to six adjacent filter units ,000 m 3 /h according to filter type High efficiency filters ceiling mounted High efficiency filters ceiling mounted are used as end filters in areas with the highest requirements for air purity and hygiene such as in the medical, biological, and pharmaceutical industries, as well as in other sensitive areas.

The air terminal device part can be folded down for easy disassembly and cleaning m 3 /h for each individual casing Filter media TROX provides filter media for its filter units for every application in industrial and clean room air handling systems. Our programme includes coarse, fine, and particulate air filters and activated carbon filters in filter grades G3 G4, F5 F9, H10 H14, and U15 U17. Specially selected filter materials and the design of the filter elements guarantee fewer pressure drops and thus cost efficiency. All filters have been tested according to European standards and are available in all conventional sizes. All filter media can be disposed of in waste incineration plants, depending on the material chosen. Städtische Krankenanstalten Düsseldorf (Municipal Hospital), Düsseldorf, Germany Coarse/fine dust filters Coarse filters are primarily used as prefilters to extract coarse to fine dust from ventilation systems. Fine dust filters are used to extract fine dust in ventilation systems with high requirements. They are available as rolls, cut-to-size filter pads, and panel filters. Filter grade: G3 F5 Nominal air stream velocity: m/s according to material 62

65 Filter media Z-Line filters Z-Line filters are especially suited for installation in standard cell frames from TROX for wall and duct installation, as well as for the standard sizes found on the market. Because they can collect large quantities of dust with only few pressure drops, they have long service lives and maintenance intervals. They stand out for their relatively low weights and small transport volumes. Filter grade: G4 Filter frame: stable cardboard frame Bag filter inserts made of chemical, synthetic or glass fibre media Bag filter inserts are used as prefilters or main filters in ventilation systems, depending on the filter type, to extract coarse and fine dust. The stable plastic front frame ensures easy disposal. This filter is available in the widest variety of standard market sizes. Filter grades: G4; F5 F 9 Bag filter lengths: mm Filter frame: plastic or galvanised sheet steel Minipleat filter inserts and cells used as fine dust and particulate filters Minipleat filter inserts are used as prefilters and terminal filters in ventilation systems that require high volume flow rates and long filter lives. The wedged shape of the minipleat filter increases the filter area and thus ensures high air flow rates with few pressure drops. Filter grade: F6 F9; H10 H14 Filter frame: plastic, galvanised sheet steel, or waterproof pulp wood. Compact filters/particulate filters Compact fine dust filters were developed for gas turbines and industrial use, wherever operating conditions are rough and also for ventilation and air conditioning systems. They are designed to resist high fluctuations in pressure and well suited for pulsating volume flows. Filter grades: F6 F9; H10 H13 Filter frame made of sendzimised or stainless sheet steel 63

66 Filters Filter media Minipleat filter panels used as fine dust and particulate filters Minipleat filter panels are used as prefilters for extracting coarse and fine dust or as high-performance filters for extracting suspended particles, aerosols, toxic dusts, viruses, microbes, and the like from supply and exhaust air. Filter grades: F7, F9; H11, H13, H14 Filter frame made of aluminium, galvanised steel frame, stainless steel, or pulp wood Minipleat filter panels for clean room technology Minipleat filter panels for clean room technology meet the highest requirements for air purity and sterility, particularly in sensitive areas such as the medical, pharmaceutical, and microelectronic industries. They are installed as the terminal item in filter ceilings, clean workbenches, and high-efficiency terminal filters, in which both the highest degree of cleanliness and controlled air flow must be guaranteed. Filter grades: H14, U15, U16, U17 Filter frame made of aluminium profile Activated carbon filter cells and inserts Activated carbon filters help adsorb odorous and harmful substances in gaseous form, for example, in airports, as well as hydrocarbons and traces of inorganic compounds. They are available as panels, cells, cartridges, and inserts for installation in walls and ducts in ventilation systems. Filter frames made of steel or moisture-resistant pulp wood, plastic. 64

67 85% of the costs caused by an air filter are energy expenses incurred during operation. The acquisition, maintenance, and disposal costs only amount to about 15% of their overall costs. To lower the energy costs, TROX has developed bag filters, fine dust filters, and high-performance particulate filters in various filter grades, by means of which up to 50% of the energy costs can be saved in comparison with conventional filter media. 65

68 Communication and automation systems... and now the weather The new headquarters of the Deutscher Wetterdienst DWD in Offenbach, Germany Project: DWD, Offenbach, Germany Owner: Hessisches Baumanagement Architect: BLFP, Frielinghaus Architekten Specialist consultant: Alhäuser + König Ingenieurbüro GmbH HVAC-contractor: Zimmer & Hälbig GmbH Fire and smoke protection solution: TROXNETCOM AS-i with basic user software and touch panel, fire dampers, duct smoke detectors The Deutscher Wetterdienst (German Weather Service) is not only responsible for the weather forecast. It has an extensive legal commission to provide information and do research, the fulfilment of which required a new headquarters. The new building for about 900 employees consists of a three to seven story administration building with two underground stories, an underground garage, a computer centre, an auditorium, a library, and conference rooms. TROX know-how was in demand for fire and smoke protection. Complex scenarios had to be implemented successfully using the TROXNETCOM AS-i technology. In close cooperation with a planning agency, the HVAC contractor, and the supplier of the centralised building management system, a thorough, open automation solution was created, into which external systems were integrated in addition to the components, software, and services of TROX. The connection of a fire detection system and coupling with the centralised building management level rounded off the overall concept. The TROXNETCOM AS-i system with TROX fire dampers and TROX duct smoke detectors with integrated touch panel for operation and visualisation can be operated autonomously. The TROXNETCOM basic user software informs the operating personnel about the current state of the plant on the touch panel and on the building management system level. Warnings, plant faults, and automated function checks of the fire protection system are displayed and recorded. Due to the early inclusion of TROX in the consulting and project planning phases, the objective of a safe, user-friendly TROXNETCOM AS-i system solution was able to be implemented in a cost-saving manner within the available time period. 66

69 Individual system design TROXNETCOM : Custom-made solutions for controlling and monitoring ventilation components Modern ventilation technology such as air terminal units, decentralised ventilation systems, and safety systems like automation systems for fire protection and smoke extraction communicate and work interactively. Data can be polled and displayed from the centralised building management system. Remote querying via the Internet or by mobile phone can subject the functionality of the systems to continuous checks while simplifying maintenance. System safety is increased by its integration into the building management systems since malfunctions can be detected and eliminated immediately. Using the power lines for data communication purposes also eliminates the conventional wiring, reducing the fire loads in a building. Furthermore, the flexible usage required of buildings today is only achieved by the use of modern communications and automation systems with which systems can be changed to meet changed requirements almost at the push of a button. TROX provides its customers with custom-made solutions for the areas of fire protection, smoke extraction, flow rate control, decentralised ventilation, laboratory air regulation, and the control of adjustable air terminal devices. TROX uses two systems to accomplish this: LON technology as an open standard in building automation, and the AS-interface, an internationally standardised industrial bus system that has been approved by TÜV for use in fire protection and smoke extraction because of its high system stability and data safety (SIL 2 according to IEC/EN 61508). The features of TROXNETCOM Digital monitoring and control of fire dampers and smoke extraction dampers, as well as limit switch recording Smoke detectors with general building inspectorate licence for detecting smoke in ventilation systems and operating fire dampers TÜV-tested compliance with the highest safety standards based on EN (VDMA ) Very easy commissioning based on the TROXNETCOM basic user software Integrated maintenance routines for checking the functioning of the fire protection components, including logging Complete LONMARK -certified LON product portfolio for fire protection LON components for controlling analogue air terminal units and adjustable diffusers Custom-made LON regulators for controlling and monitoring decentralised ventilation equipment LON laboratory control systems for regulating air pressure in rooms and volume flow rates in laboratories Advantages Integration into almost any centralised building management system Lower wiring costs Reduction of the fire loads Power line technology: 24 V and 230 V lines are simultaneously used for data communications Flexible wiring options Easiest installation and commissioning Components are delivered to the construction site already wired for use High flexibility High degree of standardisation Highest levels of system, data and operating safety according to EN Manufacturer independence due to our usage of an open standard (LON (ANSI CEA ) and the AS interfaces (EN 50295, IEC )) Reduced maintenance costs thanks to integrated function control of the fire protection systems, including documentation 67

70 Laboratory ventilation systems Futuristic laboratories with TROX technology The Novartis Campus in Basel, Switzerland One of the most ambitious construction projects in Switzerland is in progress at the Novartis Sankt Johann industrial complex in Basel. By 2030, a highly modern research, development, and management centre will be created for about 10,000 employees on the premises of the new Novartis Campus. Project: Krischanitz Building, Basel, Switzerland Architect: Professor Adolf Krischanitz Specialist consultant: Kiwi Systemingenieure und Berater HVAC contractor: ATel Gebäudetechnik Fire protection: Type FKI fire dampers with angle frames, Belimo actuators, and LON integration (also ATEX) LABCONTROL: Systems for fume cupboard and room regulation in laboratories using LONWORKS digital communication (TCU-LON II) Other products: Shut-off dampers, grilles, displacement air terminal devices, air terminal units, various swirl and ceiling diffusers, silencers, valves, multileaf dampers, and floor grilles First-class architects, designers, and consultants are creating openplan laboratory workstations for interdisciplinary cooperation in the individual buildings. The respective buildings on the Campus are being named after their architects. Special value is being placed on sustainability. The energy requirements of the Campus buildings should thus amount to only one-third of the normal energy consumption. In the medium term, the entire area should be supplied with energy generated without CO 2. For the numerous buildings of this gigantic project, TROX is supplying for components and systems for air handling, fire protection, and laboratory air management. In the Krisch anitz, Moneo, and Taniguchi buildings, for example, TROX is providing fire protection management on the basis of TROXNETCOM and laboratory air management on the basis of LABCONTROL. The LABCONTROL control system autonomously optimises the volume flow balance within the room under consideration of need-based laboratory air extraction. This balance is adapted according to the air intake speed and the degree of opening of the protective window. System data is exchanged with the building management system via a bus network. This building management system continuously controls functional reliability and energy consumption. In this way, ambitious energy saving objectives can be achieved.

71 Individual system design LABCONTROL: Custom-made solutions for safe, energy-saving laboratory air management Ventilation systems in laboratory buildings must fulfil complex, strict requirements. Protecting lab personnel and reducing energy consumption to the lowest possible levels are the main objectives. The LABCONTROL SYSTEM of TROX provides custom-made solutions that comply with these standards: from controlling and monitoring individual fume cupboards or rooms, all the way to complete ventilation systems for entire laboratory buildings. In the process, all applicable standards such as DIN 1946, Part 7, and EN are observed. Both the fume cupboard controller and the supply and exhaust air controller have very short reset times and are electronically net worked to each other guaranteeing an instant, continuous room pressure balance without a time delay whenever the fume cupboard is opened or closed. The LABCONTROL family of products also has electronic control variants that have been especially tailored for these demands. That is why our system solutions can be used in hospital areas or in the pharmaceutical industry to maintain both the required flow rates and the thermal room climates. Our electronic controllers use analogue and digital signals (LONWORKS ) to communicate. The efficient central recording and display of all system parameters, including fault messages, for example, also increase safety. The wide range of modification options allows you to build more flexible systems while remote accessing enables diagnosis and adjustment without high personnel and working-hour expenses.

72 Advanced IT Cooling Systems Optimum cooling for computer centres TROX AITCS (Advanced IT Cooling Systems) develops high-density cooling solutions based on CO 2 for the IT sector, thus playing an important role in the high availability of computer centres and the air conditioning of heavily thermally loaded IT workstations. Cooling with CO 2 The system cooling solutions are based on carbon dioxide (CO 2 ) as an energy transfer medium. Under ecological and safety aspects, CO 2 is an almost ideal cooling agent. It is nonflammable, oilfree, and chemically inactive and has only a low ozone depletion potential. It is electrically non-conductive and presents a danger to neither the server nor the electrical lines. Evaporating CO 2 is able to take up seven times the amount of heat in comparison with cold water. Both the CO 2 OLrac TM system solution for server racks in computer centres and the CO 2 OLdesk TM IT workstation air conditioning solution achieve energy savings of 30-50% in comparison with conventional systems. Project: ABN AMRO-Bank, London, Great Britain Specialist consultant: Norman Disney & Young Contractor: Mitie/Long & Partners Location: 250 Bishopsgate System: CO 2 OLrac server cooling solution Eight international awards are proof of the high performance capabilities of AITCS solutions. Defining characteristics of the technology are its maximum safety features and highest possible energy savings. AITCS solutions can be used for all commercial server racks or desk systems and are thus ideally suited to new and existing buildings and facilities. The system installed in the computer centre of the ABN AMRO Bank consists of two water-cooled cold water sets with R134A Turbocor compressors and a system water temperature of 6 /12 C. The entire project was carried out according to TIER classification N+1. The installation of the secondary CO 2 distribution system was implemented in stainless steel pipes. All 15 CO 2 OLrac rack coolers have temperature sensors, controllable fans, and a cooling capacity of 20 kw each. The total cooling capacity thus amounted to 300 kw. The rack coolers were provided as a customised solution for the bank s 600 mm x 42 HE high racks. 70

73 Blade server cooling CO 2 OLrac TM blade server cooling Intensive cooling for blade servers The CO 2 OLrac TM cooling system works with CO 2 as the heat transfer medium. By means of a perforated front panel door, inside air is conducted through the blade servers through several fans on the back side of the rack. In the process, the air takes up the heat of the blade servers and cools them. The heated air is then cooled down to room temperature again in the heat exchangers, which are operated using CO 2. The heavily thermally loaded rack thus does not have to be in the same room as the existing air conditioning system and does not require a cooling/heating path constellation. Thanks to the high cooling capacity of 30 kw and more per rack, the highest possible packing density of blade servers in the server racks can be achieved. With respect to the use of conventional air conditioning, using the high-performance energy transfer medium saves more than 50% space in the technical infrastructure area of a data centre, as the number of server racks is reduced and a clearly higher room capacity is achieved. Along with this enormous cooling capacity, energy savings of more than 50% can be generated in comparison with conventional systems based on cold water and other cooling agents. CO 2 OLrac TM can be used for all commercial server racks and is ideally suited for both new and existing computer centres. 22 C +/- 35/40 C 24 C +/- Advantages of the CO 2 OLrac system: - High cooling capacity of more than 30 kw per rack - Highest possible packing density of the server racks - Reduction of the technical infrastructure areas to up to 50% - 50% energy savings in comparison with conventional cooling - Can be used for all conventional server racks - Highest security due to a CO 2 detection system - For new and existing computer centres 22 C Normal operation 22 C Open rack 24 C +/- e-chain system, flexible four-wire - connection, N+1 71

74 Advanced IT cooling systems Dealer desk cooling CO 2 OLdesk TM dealer desk cooling Intensive cooling for dealer desks With the development of CO 2 OLdesk TM, TROX AITCS offers intensive cooling for dealer desks. This high-performance desk air conditioning system was developed to fulfil the requirements of investment banks for the equipment of high-performance workstations. Function: The heat loads arising in the dealer desks due to computers and other heat sources are directly dissipated via the CO 2 OLdesk TM system. The cooling creates a microclimate that is confined to the individual workstation. The concept guarantees an optimum adaptation of CO 2 OLdesk to the computer heat load to be removed. The self-regulating system lets users set up their computer tower on either side of the workstation. The high-density cooling system uses CO 2 as a heat transfer medium. For the installed data processing technology it presents no potential dangers in comparison with water-based cooling and enables energy savings from 10 to 30% due to the low power consumption. CO 2 detection systems continuously monitor the CO 2 concentration in the room and guarantee an early warning using acoustic and visual signals in case CO 2 escapes. On the whole, CO 2 OLdesk comes off well in system comparisons.the system offers great cooling capacity in the dealer halls and optimum workstation comfort without impairment of the air conditioning. Advantages of the CO 2 OLdesk system: - Heat loads are dissipated directly at the source - High specific cooling capacity - CO 2 OLdesk can be used for all commercial desk systems - For new and existing dealer desks - Space-saving integration into false floors due to low construction height - Up to 30% energy savings in comparison with alternatives operated with cold water - Versatile, individual areas of application Dealer desk with CO 2 OLdesk (recessed installation) 72

75 Plant description CO 2 plant options: To complete the high density system, a CO 2 plant option is specified: CO 2 OLpac TM When an existing building has sufficient chilled water to cool the high density server load, a CO 2 OLpac solution is specified. The server heat within the vapourised CO 2 is rejected via the CO 2 OLpac heat exchanger into the existing chilled water system. CO 2 OLpac units are available from 100 kw to 600 kw. CO 2 OLpac TM CO 2 OLairpac TM Where the building s cooling infrastructure is to be enhanced to satisfy an increased heat load, either the CO 2 OLairpac or CO 2 OLwaterpac are specified. Both chillers provide a packaged plant solution to compliment a dedicated high density server cooling system. For the CO 2 OLairpac, aircooled R134a chiller with integral CO 2 OLpac, modules are available from 300kW to 750kW capacities. CO 2 OLairpac TM CO 2 OLwaterpac TM The CO 2 OLwaterpac solution is a water-cooled R134a chiller with integrated CO 2 OLpac module designed to suit cooling tower systems. This compact unit is available in modules from 300 kw to 900 kw. CO 2 OLwaterpac TM 73

76 Insufficient cooling in computer centres often leads to server failures. For this reason, the cooling of these devices is vital and accordingly consumes many resources. In 2006, the U.S. Environmental Protection Agency has calculated that the servers and memory systems and equipment used to cool these systems in computer centres on American soil in the United States cost 61 billion kilowatt hours of electricity. This is twice as much as in 2000 and makes up 1.5% of the national power consumption. If the power consumption of the computer centres continues to rise at the same rate as at the beginning of the century, it will reach about 100 kilowatt hours by 2011 according to the EPA.
