Heat Pipe Vacuum Tube Solar Collector Features
1) Can be matched with any low pressure, high pressure hot water system.
2) Use heat pipe for the heat conduction and can get a high heat absorbtion efficiency and rapid heat transfer.
3) Easy plug-in design and installation.
4) Corrosion-resist Aluminium manifold and frame.
5) Optional 38° /45° frame can resists wind with a velocity of 36m/s.
6) Can supply hot water to large amount water needer.
7) Economical for hotel, school, domitory, hospital and tall high-buildings.
