CPK7210 Flat Plate Solar Collector

The CPK7210 Flat panel collector is one of the most efficient collectors in the world with an optical efficiency of 81.8%. One of the unique features of the CPK7210 is that the collector is extruded from a single aluminium sheet thus removing the need for welds, joints or glueing at the corners
Other features
  • Glass is a special tempered solar glass
  • Absorber is constructed from a single sheet of Tinox selective absorber coating.
  • Heat transfer pipes behind the absorber are ultrasonically welded along the entire length to ensure optimal heat transfer. 
  • 50mm of mineral wool insulation.
