Solar collector CSAL 20 RS is provided with an alluminium absorber plate with high selective coating made of TiNOx Energy Al, wich allows an energy absorption of 95% from the sun’s rays on the surface and reduces its emission to 4%. The absorber plate is ultrasonically welded to 10 copper harp-shaped pipes trough wich the heat-transfer fluid runs.
The tempered solar glass, wich is 3.2 mm thickness, along with the rock wool insulation, wich is 30 mm thickness on the bottom side, ensure high efficiency even in case of bad weather conditions.
The solar collector has been designed with four 1’’ fittings to make the connection in series of collectors easier (up to a max of 6) and to ensure low head losses (the heat-trasfer liquid flows trough the collectors in parallel) and high efficiency.
Two of the four connections need to be closed by brass screw plugs.
A film is provided as standard to protect the collector from overheating before the system starts working.
The solar collector complies with the EN 12975 directive and is Solar Keymark certified.
A wide range of accessories and fixing elements is available to meet all installation requirements.
