Solar DHW tank SKL Solar energy rationally stored ... Inside enamelled solar domestic hot water tank for central hot water supply, two heat exchangers with big surface, prepared for auxiliary heating by an electrical element. Available standard sizes 200, 300, 400, 500, 750 und 1000 litres. Perfectly aligned for solar systems Hygiene in the high performance DHW tank SKL is guaranteed by heating up the special heat exchangers during solar operation. The high power solar exchanger is decisive for the performance of the solar system. The temperature in the solar return line of the SKL is up to 15°C lower than with regular DHW tanks and with their regular heat exchangers due to its arrangement far down of the tank. Thus, the efficiency factor of the solar system and the performance of the collectors is increased up to 15%. Due to the supplementary heat exchanger, which is located in the upper part of the tank, the heating value is guaranteed even when heating up with a condensing boiler. Therefore, the DHW output capacity of our tanks is a lot higher than the output capacity of regular solar tanks. An interconnection of both heat exchangers is possible to get an high performance anti-legionella tank, p. ex. for the application with heat pumps or in the hotel industry. Take advantage of these benefits perfectly aligned for all solar systems also suitable for condensing technology twin coil tank, two plain tube heat exchangers (solar and heating) high quality steel S235JR internal corrosion protection with double enameling (Made in Germany) magnesia anode installed insulation for SKL 200 to SKL 500: PU rigid foam (non-removable), insulation thickness approx. 50 mm insulation for SKL 750 and SKL 1000: removable flexible foam insulation WLG 0,039, insulation thickness approx. 75 mm silver PVC jacket, fire protection classification: B2 installation of an electric heating element possible
