C-Channel grid system The C-Channel grid system allows post installation modifications to the room geometry. The modules are placed on wide support tracks (strips). This allows easy retrofitting of partition walls. Flexibility and time-savings are essential benefits, particularly when re-planning a room. Inspection/modification is possible for each cassette. This ensures quick access to the ceiling void. The C-Channel grid system is ideally suitable for use with larger module sizes (max. 1.5 m ). No special tools are required to open and close the ceiling panels. Further information: Sound absorption Page 17 Heating and cooling performance Page Technical data Page 4 4

Lay-in system The lay-in system is specially tailored for use in new or existing grid ceilings. The available basic grid dimensions are 600 mm and 65 mm. The lay-in modules come in two standard widths and in five standard lengths. The length of these various lay-in modules is based on the basic grid dimension and can be up to five times the basic grid dimension. The panels are ideal for larger surfaces (max. m²). The use of longer modules can reduce the cost of installation by up to 80% compared to conventional systems available on the market. For the lay-in system, the modules are placed on a T-shaped substructure. Zehnder lay-in systems can be activated in two different ways: Activation by aluminium heatconducting profiles and copper pipe meander. Activation by graphite sandwich with integrated copper pipe meander. Further information: Sound absorption Page 17 Heating and cooling performance Page Technical data Page 4 10

Wall connections A variety of wall connections can be used to match the appearance of closed ceiling systems to the room geometry. For example, an L-bracket that connects directly to the vertical wall (Fig. 1). Edge angle for inactive panels cut on site (Fig. 1) The graded-edge angle that distinguishes the cooling ceiling from the wall is an ideal way to obtain the impression of a shadow gap at the wall (Fig. +3). A further advantage of this wall bracket is the F-lip in the profile (Fig. +4). The cut edges of the ceiling panels are inserted into the lip here to prevent lifting or curving of the module. Graded-edge angle with F-lip for inactive panels cut on site (Fig. ) Graded-edge angle for installed inactive panels (Fig. 3) Edge angle with F-lip for inactive panels cut on site (Fig. 4) Edge angle for installed inactive panels (Fig. 5) 1

Ceiling sails Zehnder ceiling sails are the energy-efficient, cost-effective solution for heating and cooling rooms. As they only require a short space under the structural ceiling, they are even ideal for properties with low room heights. The dimensions of Zehnder ceiling sails can be tailored to suit the individual requirements of any plan. Our various installation kits for suspending and securing the ceiling sails integrate seamlessly into your overall ceiling layout. Zehnder ceiling sails can be activated in two different ways: Activation by aluminium heat-conducting profiles and copper pipe meander. Activation by graphite sandwich with integrated copper pipe meander. Further benefits of the ceiling sails: Fast and straightforward installation Very high sound absorption Available in numerous colours Further information: Sound absorption Page 17 Heating and cooling performance Page Technical data Page 4 14

Surfaces and colours Grid version Zehnder heating and cooling ceiling modules are available with the option of a smooth or perforated surface. The surface is coated with a high-quality powder coat finish. Zehnder ceiling modules are available in the standard colour similar to RAL 9016. Sail version Further colours on request. Perforation Zehnder Alumline: 4,00 4,00 The perforation in the Zehnder heating and cooling ceiling modules also has a significant influence on the absorption characteristics.

Sound absorption Zehnder heating and cooling ceiling systems can be used for sound absorption: The sound waves are absorbed by the fleece at the back and by the inserted insulation material. This results in a significant reduction of the noise level and a reduction in the reverberation time (e.g. in open-plan offices, call centres and schools). Please contact us if you require detailed information on calculating the acoustics.

Graphite activation Zehnder Carboline Insulation Zehnder Carboline: The ideal properties of the expanded natural graphite material, which is excellent at distributing heat quickly and evenly throughout the room, combine high thermal conductivity with minimal weight. Sheet steel Graphite Copper pipe The thermography shows the comparison between Zehnder Carboline (radiant panel system on left) and a standard panel, both exposed to the same flow temperature and mass flow. Zehnder Carboline exhibits a higher surface temperature. C 70.0 60.0 C 70.0 60.0 Θ = average surface temperature Θ 65. C 50.0 Θ 61.

Aluminium activation Zehnder Alumline Insulation Zehnder Alumline: The special D-shape of the copper pipe increases the surface area for thermal transfer to the aluminium heat-conducting profile and to the sheet steel. In this way, the method of transfer is utilized most effectively. Sheet steel Aluminium heat-conducting profile Copper pipe The thermograph shows that the D-pipe produces a more even and more pronounced thermal transfer than a conventional 10 mm round tube. This is achieved by fully embedding the pipe, and on account of the large contact area of the pipe on the heating and cooling module. Energy savings are possible due to the higher surface temperature at the same flow temperature and mass flow.

Connection options For Zehnder heating and cooling ceiling systems, both connection pipes are located on the same end. This enables an installation friendly and quick connection of the radiant panel systems. Connector technology Special connector hoses are used to connect several individual elements to each other; they are connected directly to the pipes with no need for additional tooling. 0
Special solutions Ceiling cut-outs can be integrated into the panel elements of Zehnder heating and cooling ceiling systems as required. Ideal for offices or meeting rooms, ceiling recesses are possible, e.g. for air outlets, projector brackets, loudspeakers, fire alarms or lighting. Zehnder produces the required ceiling cut-outs precisely to the customer s specifications. Special solutions 1

Applications Public building The heating and cooling ceilings also integrate as an architectural design element for modern, suspended ceiling light fittings, for example. Generous, bright clarity of form and structure an inviting atmosphere where customers will feel comfortable. Schools The generous foyer exhibits clarity of design, is modern and has an open layout. The heating and cooling ceiling systems also integrate ideally into the design concept. Besides visual aspects, performance features such as energy efficiency, costs and reliability are important considerations in open rooms. 6
Office buildings Comfortable indoor climate in the meeting room. Besides the demand for cost-effective heating and cooling, the aim was to provide an aesthetic solution for the heat distribution system, particularly in conference rooms. The lighting and air outlets also harmonize with the cooling ceiling. University Architects use colour and light as a means of visual enhancement here. The harmonious integration of the heating and cooling ceiling system underlines the special atmosphere. Design demands blend with a comfortable indoor climate for top performance in any season.
