Specifications

Energy saving, extremely low use cost at ordinary times

Tri-element tubes consist of two glass tubes which are fused together at one end. The inner tube

is coated with a selective coating with 12 layers of spattering deposition technology that absorbs

solar energy well. The coating is ALN/AIN-SS/CU by gradual change techniques,

which has better heating efficiency.

The air is withdrawn ("evacuated") from the space between the two glass tubes to form a vacuum,

which eliminates conductive and convective heat loss. Therefore, evacuated tubes could achieve up

to 380degree from theoretical condition, and act as the key component of solar water heater

1) Combines glass vacuum tube and copper heated pipe to form a heat pipe tube.

2) No water in copper heated pipe, which shortened the heating time.

3) Without water in glass vacuum tube, product can be used in cold weather of -30 Celsius degree

4) Widely used for pressurized solar water heaters and solar projects

5) Individual tube can work independently, solar water heater can still work in case of tube is broken. The warranty time of tubes are as long as 15 years

Working Pinciple:

The selective coating on the inner tube collect solar energy and heat

the heat pipe through the aluminium fins. The liquid in the heat pipe changes into vapour and then rise up to transfer the heat to the condenser. Vapour becomes liquid after the heat been transferred. The process occurs again and again once the collector(s) is/are heated by the sun.
