HR
Range of internal double coil accumulators suitable for heating environments and the production of domestic hot water for domestic and residential buildings.
The accumulator is suitable for containing hot technical water.
The lower coil is designed to have the maximum exchange yield with solar collectors.
The production of hot water is instantaneous due to the internal corrugated stainless steel coil throughout the entire accumulator volume.KSF-D25
The KSF D25 collector is particularly sturdy thanks to the reinforced and welded aluminium profile frame and the 4 mm thick glass. It is also easy to install and connect thanks to the connections with 22 mm diameter copper tube.

• KSF-D25 idra basic set needed at the end of each string and made up of 1 brass body including probe-holder fitting with seal, manual air vent and coupling with sealing o-ring for connection to the hot side return and 2 string closure caps;
• KSF-D25 idra plus set needed to combine two collectors in series, made up of 2 joints;

Cover with 4.0 mm anti-reflective tempered, high transparency glass to ensure maximum light transmission, capable of capturing as much energy as possible as well as being treated internally to reflect the infrared rays generated by the absorber, thus retaining the heat otherwise emitted externally by the heated glass.
