6 Company profile CONSTANTLY GrOWING ALL OVEr THE WOrLD Uniflair was founded at the end of 1988 and quickly managed to conquer an important position among the biggest manufacturers in the world of air conditioning for technological application, as well as chillers and modular access flooring. Initially it only dealt with the national market, however Uniflair s expansion has now reached Europe and the other continents. It currently has over 60 distributors. The company s considerable expansion has made it necessary to adapt its working space. Thus, from the first factory measuring 1,200 m², Uniflair has recently moved to a new site which, with a surface area of over 120,000 m², makes use of a production area of 30,000 m², training rooms, conference halls and one of the most innovative research centres in Europe. RESE ArCH AND INNOVATION Innovation has always been the mainstay of Uniflair s development:considerable company resources have been invested in research into new application solutions intended to assure product excellence with an unbeatable level of reliability. The whole production and management system is run based on an ISO 9001 certified quality model, Uniflair has also achieved ISO certification. 4

7 Products CLO S E CO N T r O L - Pr E C I S I O N AIr CO N D I T I O N I N G Any type of living organism requires a suitable environment in order to operate at its best. Advanced technological applications need accurate and precise management of the thermo-hygrometric environmental conditions which are necessary to ensure correct operation and increased reliability. In order to respond to continuous technological evolution, a precise and accurate air conditioning system is fundamental since it is able, thanks to new technological solutions and component innovation, to create the correct conditions for optimum operation of the whole system. Uniflair precision air conditioning units are extremely reliable in terms of operation and precision, they are environmentally friendly and particular attention has been paid to energy efficiency. TE C H N I C A L C O O L I N G - CO O L I N G S Y S T E M S Combining avant-garde technology with energy efficiency while protecting the environment at the same time is the challenge which has inspired Uniflair to produce this new range of products designed for technical cooling. Air conditioning technological environments, cooling industrial processes and providing comfort cooling combined with high levels of performance are all types of applications where the ideal solutions are chillers and heat pumps belonging to the technical cooling series. Many years of experience combined with the company s position as a market leader in the air conditioning sector has enabled Uniflair s designers to make the technical and operational choices necessary to create optimum technical excellency. UN I F L A I r MO D u L A r AC C E S S FL O O r S The development of new technology combined with the need to create new spaces and modify environments has led to new architectural and operational demands for designers. Uniflair has an avant-garde Modular Access Floor production line which is able to meet each client s specific needs. The annual production capacity is more than square meters and quality is ensured by a continuous supervision control system at each manufacturing stage. Moreover, some of Uniflair s exclusive processes are patented. The aesthetic-functional value of each building is increased by a wide range of flexible, innovative, practical and elegant solutions suitable for any type of building context, ensuring added value for the client. 5

8 Why Uniflair EFFICIENCY AND RELIABILIT Y The issue of energy continues to play an extremely important role regarding operating costs for modern systems. Uniflair s range of products makes it possible to guarantee maximum service reliability while cutting energy consumption to a minimum: Indirect free-cooling High efficiency refrigerants Efficiency at partial loads (tandem) Oil-free centrifugal compressors with magnetic bearings Modularity and flexibility Inverter driven compressors Optimized set-point Double screw compressors Less CO 2 ADVANCED CONTrOLS Uniflair produces the software for its units internally. This enables the company to equip each machine with a tailor made control which manages all aspects of the unit. Absolute control means: Precision: the units use advanced algorithms to accurately control the temperature of the chilled water Reliability: each component is continuously monitored to guarantee it is always used within operating limits and will signal any faults before breakdown occurs Local Area Network: Aquaflair chillers can talk to each other, resulting in excellent control of multi-unit systems, managing all the cooling resources and units on stand-by (either on a time basis or alarm) Connectivity: Uniflair microprocessor controls can talk to the most common supervision systems (Building Management Systems) including: Modbus, Bacnet, LonWorks, Trend, Metasys, TCP/IP and SNMP 6

9 Op T IMI Z E D M A N A G E M E N T Management of the whole system allows energy consumption to be optimized and strategies of integrated control to be implemented which would otherwise not be possible. Uniflair s precision air conditioning units, Active Floor modules and chillers can be linked together by a LAN, maximising the operating parameters and the real needs of the system. Particular attention has been paid to the management logic which is aimed at reducing the energy requirement by means of a tracking logic for the current thermal load. The temperature of the chilled water varies dynamically in such a way as to minimize compressor consumption and the use of free-cooling, maintaining the desired temperature within the room. Energetic efficiency [%] Water Temperature [C ] 0 0 Min load Mittle load Mittle load Max load EER Operating water temperature Number of Units ON ACOuSTIC IMpACT Reduction in sound pollution is one of the most critical factors designers are called on to solve when choosing plant systems. Uniflair chillers offer low-noise solutions with extremely low acoustic impact thanks to: Acousti-composite fans with high efficiency and low acoustic impact Extra-large air side exchangers Specially devised and implemented algorithms which control the rotation speed of the fans Tested, optimised compressor insulation and housing Livello di pressione sonora [db(a)] kw 1100 Uniflair unit comparision (blue line) with its main competitors Acoustic levels for a basic high capacity unit, Tambient: 35 C, Twater in/out: 12/7 C, distance 10 m, Q=2, condensing coil side 7

10 Standard Chiller Traditional Free-cooling Uniflair Free-cooling Free-cooling Free-cooling coil Free-cooling pump pump evaporator pump When a system is used for technological or industrial processes which operate all year round, it is important in terms of energy saving to use solutions which exploit these conditions. Chillers equipped with free-cooling devices not only reduce energy consumption compared to traditional systems but also limit CO 2 emissions into the atmosphere, contributing therefore to reducing global warming. When the external temperature is low enough, the free-cooling system produces chilled water using external air only, significantly reducing energy consumption since it is limited to the fans.

11 Intelligent Free-cooling DIrECT EXpANSION MODE MIXED MODE The need to install a stand-by unit can be exploited to increase the free-cooling capacity. By interconnecting the circuits of the free-cooling units it is possible to make the water flow through all of the available exchangers therefore further decreasing energy consumption. Additional annual energy saving Compared to traditional Free-cooling: up to 7% depending on the climate Compared to a traditional system: up to 50% FrEE-COOLING MODE Annual energy saving Uniflair Vs Uniflair Free-cooling Intelligent Free-cooling Energy saving [kwh] Economic saving Frankfurt % Milan % Paris % Amsterdam % Madrid % Berlin % London % GL Y C O L-F r E E Free-cooling coil pump Free-cooling pump pump evaporator Created for applications where the use of anti-freeze solutions are not permitted, this solution, thanks to an intermediate heat exchanger, isolates the principal hydraulic circuit from the free-cooling circuit. Careful selection of the intermediate heat exchanger allows the delta T to be limited to only 2 C, reducing therefore the energy drops which are intrinsic to this system. 9
