Evacuated tubular solar thermal collector / with aluminum frame / rectangular
REGULUS SPOL SRO
with aluminum frame
Vacuum insulation in glass tubes. Two concentric glass tubes are used, with vacuum between them. The ends of the tubes are sealed so the vacuum is guaranteed for a long time. Vacuum surrounding the absorber is a perfect insulation, minimizing heat losses in a similar way like a vacuum flask does. Thanks to that, nor the tiniest heat gain from cloudy skies gets lost and warms up the fluid in the solar collector.
