Features
Singular vacuum tube type solar collector, technically allianced with German, is high efficiency suitable on high temperature collector.
Singular vacuum tube type maintain the vacuum condition as 10-3Pa. To cause the semi-permanent lifespan, the vacuum glass tube and glass tube has been attached additionally to product through manufacturing process. Compare with other singular vacuum tube type solar collector products, efficiency and quality is excellent.
Collectively absorbed plank convert absorbed solar energy 95% exactly, and high thermal efficiently can be created by...
