Low pressurized solar thermal collector
solar thermal collector is a passive solar system which absorbing core is evacuated tubes. The water in the evacuated tubes is heated by solar energy which absorbing by coating of tubes.The manifold water is alway lower than the tubes water while passive circulation.cold water goes down to exchange the hot water in tubes. Once the temperature of manifold water reaches the requested value,it would be actively circulated to the main big solar water heater tank or passively exchange the hot water with cold water of solar water heater tank.

What's the solar thermal collector advantage from others.
It can be installed split with solar water tank.working with circulations for active system .Or install lower than big tank
for natural circulation.
Our inner manifold is made of 0.4mm 304 food grade steel, though it is working under zero pressure bar, but with this material thicker can against for sudden pressure rising such as block of the pipeline and first running system with circulation pump working.
We adopts automatical argon-arc welding to protect the stainless steel from destroy.Lower down the risk of rust.
The other size and material are available for you.
1.inner tank : can be SUS304-2B and SS316L
2.Out tank shell can be SS 201 stainless steel ,color steel ,pvdf steel
3.Frame available in Aluminum alloy ,stainless steel 201,galvanized steel with powder coating.
