1. TECHNICAL DESCRIPTION
The collectors of this series are drysealed without silicone. 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
50 mm. A special modular mounting system was developed for the series which
makes it possible to realise standalone, roof-integrated and roofmounted solutions
with equal ease.
