Flat plate solar collectors Tesy SP 08 260 CSL

Description

Flat plate solar collectors with a selective absorber aluminium absorber Tesy SP 08 260 CSL

Flat aluminum absorber welded with LASER technology.
Selective coating ensures a high efficiency of the collector.
The prismatic glass (reduced amount of cast iron) retains the accumulated heat and allows the passage of the maximum amount of solar radiation to the absorber.
Mineral wool insulation guarantees minimum heat loss in extreme conditions.
