Pressurized solar collector

Use of solar collector:
The solar collector normally used in split and pressurized solar water heater, the solar collector connect with pressurized solar tank.

Features of pressurized solar collector:
1, The solar collector is pressurized, so it can working under 10bar pressure.
2, The solar collector is separated with solar tank, so it can install at any sunshine place.
3, All the tube is high borosilicate glass, the coating is CU/SS/ALN, have more heating efficiency.
4, Inside of vacuum tube, there are aluminium fin and copper heat pipe, acceleration heat transfer
5, The tube is closed, no water into vacuum tube, has a good ability to antifreeze in cold weather.
6, Internal of solar manifold, have copper flow passage, liquid is heated inside of copper flow passage, it's just as heat transfer media, the liquid is not for use directly, so the liquid can be pure water, also it can be antifreeze or others heat transfer liquid.

Material of pressurized solar collector:
1, Solar manifold:
Internal: Copper flow passage
Insulation layer: Polyurethan foam
Outer shell: Aluminium alloy
2, Tube:
Vacuum tube: Two layers high borosilicate glass vacuum tube with Cu/SS/ALN coating
Internal of vacuum tube: Aluminium fin and copper heat pipe
Specification: φ 58mm/1800mm, φ 47mm/1500mm for optional
3, Frame:
Galvanized steel with powder coating (stainless steel or aluminium alloy for optional)
4, Tube holder on bottom: Nylon adjustable tube holder

Usefull life: 15years
