Zehnder ZIP Radiant Ceiling Panels
The Sun – a masterpiece!
The sun radiates warmth and light. Its thermal radiation is only effective when its rays shine on an object. The air is therefore not warmed directly. Even when the air is very cold it is possible to feel warm in the sun. The decisive factors for our personal 2
thermal comfort are the average values of
3
the ambient temperature and those of the surrounding surfaces. Zehnder ZIP radiant ceiling panels for heating applies this natural principle. The perceived temperature is about 3° C higher than the air temperature, resulting in comfort at a lower room temperature. Zehnder ZIP radiant ceiling panels reduce costs. Heated by hot water, maintenance is minimal and service life is unlimited, saving energy and money. Zehnder ZIP radiant ceiling panels create healthy warmth. They operate without causing air movement and consequently do not swirl dust about. This in turn assists in the prevention of allergies and illnesses. Range of Application: Rooms from 3 m to 30 m high, such as production and storage facilities, workshops, sports halls, garages, sales rooms, shipyards, maintenance shops, damp locations, etc. Zehnder is Europe’s leading supplier of radiant ceiling panels, with decades of invaluable experience.

Excellent Technology.
Zehnder creates an entirely new system: Zehnder ZIP Radiant Ceiling Panels. The many advantages are:
• Easy to store. Only one module width – 320 mm – uses storage space effectively. • Flexible, straightforward fastening system. Simplifies installation as well as
• Optional connection method: threaded or press fit connections. No welding required. This simplifies installation and facilitates easy system extension when premises are enlarged. • Lightweight. Easy to assemble and install. • Installation-compatible. Shorter installation time means reduced costs. • High heat emission (tested in accordance with EN 14037). The efficient heat
reconfiguration or extension. • Attractive slimline appearance, with 15 mm. Diameter tubes. • Rapid reaction time. Thanks to low storage mass and low water content. • Corrosion prevention. The Zehnder ZIP radiant ceiling panels are corrosion inhibited. The relevant test was carried out in accordance with DIN 50017 ”Condensation Water Test Atmospheres“.
