FK 7300 GLAZED
FLAT PLATE
COLLECTOR
The collectors of this series are dry sealed without silicine. The solar glass cover is sealed by
means of an uncemented rubber frame. The full-face absorber is bedded in an aluminium
trough on a layer of rockwool with a thickness of 50mm. A special modular mounting system
was developed for the series which makes it possible to realise stand-alone (A-frame
mounted) and roof mounted solutions with equal ease.
