OKF-CK22 Flat-plate collector


The OKF-CK22 flat-plate collectors can be used for hot potable water preparation, solar backup heating and swimming pool heating. They can be used in landscape or portrait format for on-roof installation or free-standing installation (flat roof installation). In-roof installation in portrait format is also possible.

The flat-plate collectors have a collector cover with matt anti-reflective glass for 96 % light transmission, a laser welded aluminium double harp absorber with copper pipe register for optimal energy yield and low pressure loss, a rear wall insulation and a circumferential frame insulation made of mineral wool and a UV-resistant EPDM glass seal.

Due to the high-quality materials used, the flat-plate collectors achieve a high degree of efficiency. In addition, they feature plug-in connections and pre-assembled rail systems and are therefore characterized by simple “plug and play” installation.
