Distinguishing features of the K420 DH roof mounted flat panel solar heating system is its optimised aperture area, their high efficiency and elegant design, as well as simple and flexible installation. The new collector housing contains laser-welded Cu or Al absorbers with 2 hydraulic interfaces on the top of the collector.
The rigorous prevention of thermal bridges allows the highest output levels. The secure glass mount featuring two separate sealing levels made of UV-resistant material guarantee ultimate product reliability and durability. The frame profiles are manufactured from high-strength, corrosion-protected aluminium. They are available in a number of RAL colours.
