Specifications

vacuum tube solar water heater:
Copper is the important material of our solar water heater,which make the absorption highly.

 vacuum tube solar water heater collectors:

 

Resist the frozen weather

Cu-Ss-Al absorb coating

The tube has the following advantages:

1)      Absorptivity:0.94-0.96

 because of the copper insulation,the absorption of stainless steel and the decline heat of Aluminium layer.

2)      Endure bad weather

Our evacuated tube can endure temperature to 250^.C,even under -50^.C since the vacuum rate can reach less than 5.0×10^-3pa.

3)      Structure stability

The tube prssure-endure ability can reach 1Mpa

4)  Long life

Patented conducting substance is compatible with normal metal material that result in non-condensable gas and non-stop running within 15 years and long duration for the collector.

5)  Advanced technology

Our company use 3 target magnetron sputtering plating technology,which introduce from Germany and also called interferometer coating technology.

We have different diametical tubes, for example,47mm,58mm,70mm of external pipe.
