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 thermal comfort are the average values of the ambient temperature and those of the surrounding surfaces. Zehnder Rittling ZIP Radiant Ceiling Panels for heating applies this natural principle. The perceived temperature is about 37 F higher than the air temperature, resulting in comfort at a lower room temperature. Zehnder Rittling ZIP Radiant Ceiling Panels reduce costs. Heated by hot water, maintenance is minimal and service life is unlimited, saving energy and money. Zehnder Rittling 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 10' to 100' high, such as production and storage facilities, workshops, sports halls, garages, sales rooms, shipyards, maintenance shops, damp locations, etc. Overview 2 Features 4 General Data 6 Dimensions and data 7 Suspension Systems 13 Connections 15 Panel specifications 18 Warranty 20 1
Excellent technology Zehnder Rittling creates an entirely new system: Zehnder Rittling ZIP Radiant Ceiling Panels. The many advantages are: Choice of connection methods You choose threaded or press fit connections. No welding required. This simplifies installation and facilitates easy system extension when premises are enlarged. Installation-compatible Shorter installation time means reduced costs. High heat emission Tested in accordance with EN 14037. The efficient heat transfer design of the Zehnder Rittling ZIP Radiant Ceiling Panels ensure the highest possible heat output, further reducing costs. Modular construction Ranging from nominal 6 ft 20 ft, the unique, modular concept of the Zehnder Rittling ZIP radiant ceiling panel system offers the right solution for any installation situation. For the very first time, modules can be arranged end to end or side by side, as required. Lightweight Easy to assemble and install. Easy to store Only one module width 12-5/8" uses storage space effectively. Flexible, straightforward fastening system Simplifies installation as well as reconfiguration or extension. Attractive slimline appearance 15 mm (5/8") diameter tubes. Rapid reaction time Due to low storage mass and low water content. Corrosion prevention The Zehnder Rittling ZIP Radiant Ceiling Panels are corrosion inhibited. The relevant test was carried out in accordance with DIN 50017 Condensation Water Test Atmospheres. Special version for high humidity locations Zehnder Rittling ZIP Radiant Ceiling Panels are suitable for locations that have high moisture content, such as washrooms and pool areas. Zehnder ZIP Radiant Ceiling Panels are ideal for integration into modern architecture. 2
Overview 3
Features: Zehnder Rittling ZIP Radiant Ceiling Panel, made of 26 gauge sheet steel galvanized on both sides, with Zehnder Rittling special clip profiling to accommodate four 15 mm (5/8") O.D. precision steel tubes in line with DIN EN 10305-3. Outside surface of radiation panel coated with polyester lacquer similar to RAL 9016, opposite side with protecting lacquer. Suitable for operating temperatures up to 203 F (95 C), maximum operating pressure 73 PSIG (5 Bar). Folded side flanges and galvanized box-section crossbars stiffen the steel sheeting and provide mounting for suspension. Two sheet-metal end elements close off the ends of the radiant panels. Installation set A panel can be attached directly to the integral suspension bars in a fixed grid arrangement or, if several are arranged in parallel, by using a common multi-suspension bar with only two points for fixing to the ceiling. The 1-1/4" (32 mm) diameter tubular headers are furnished with a 1" externally threaded connection boss, blank cover and an oppositely located 1/2" sleeve as vent/drain. The headers are supplied loose and are installed on site. They are connected to the panel or the panel modules by tightening the threaded couplings. The 12-5/8" (320 mm) wide modules are supplied, ready-to-install, in nominal lengths of 6.6' (2m), 9.8' (3m), 13.1' (4m), 16.4' (5m), 19.7' (6m) according to requirements. The individual modules are joined with threaded or press fit connectors. The joints are concealed with clip fit, lacquer finished, cover plates. The Zehnder Rittling ZIP Radiant Ceiling Panels are protected against corrosion. The relevant test was carried out in accordance with DIN 50017 Condensation Water Test Atmosphere. There is also a version especially for damp locations. This includes fitted insulation with a galvanized top cover added on site. Compression coupling: 15 mm (5/8") galvanized compression fittings. Threaded coupling: 15 mm (5/8") galvanized clampring coupling. Connector Technology: If you are using two or more individual elements, they will need to be connected to one another. The individual elements are assembled into the desired configuration by means of pressfit connections and the joints are then hidden under a cover. The headers are painted as standard, so all you see is great design. Reinforcement bar Insulation Radiant panel Precision steel pipe 15 mm x 1 mm Press fittings shown 4
