We have applied our longstanding experience in the development of various collector types to our fourth generation of flat plate collectors.
Distinguishing features of the K4 Collectors are their 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 or 4 connectors.
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 full range of RAL colours.
For applications in southern Europe, the K4 is also available with reduced insulation, making it just 70 mm high, as compared to conventional collector heights of up to 95 mm. This offers distinct advantages in terms of weight, transportation, handling and last but not least, price. Our standard collector models are certified with the Solar Keymark.
