ust like an automobile engine, the computer CPU, evacuated tube is the solar water heater. Its performance lies on the coating technology, The three-target evacuated tube rise the heat more than 12% 1) High temperature: by special interference-layer it could bear the high temperature reach to 500℃, and the coating will not shed and aging. 2) Super...more

Features: 1) Structure: all glass coaxial dual tube 2) Material: high borosilicate glass 3.3 3) Interferential coating: aluminum nitride 4) Capabilities: a) Fast thermal collecting efficiency b) High heat resistance c) High cold resistance 5) Life time: 15 years.

1. When the discrepant temperature of the solar collector and water tank reaches the set value, the controller shall start the circulation pump automatically ; 2. The circulation pump makes heat-conducting liquid circulate automatically; 3. The heat-conducting liquid transfers heat to water by heat exchanger in the water tank 4. In case the temperature...more

We provide Highly-Absorptive Vacuum Tube. Features: Kaidun Highly-absorptive Vacuum Tube is made of borosilicate glass, which applies the advanced 12-layer of spattering deposition technology of gradual change of ALN/AIN-SS/CU selective absorptive coating. This makes the vacuum tubes highly absorptive and highly durable to high temperature and...more
