Flat solar collector

1.high absorptivity & low emissivity
2.combining with building ideally
3.with strong pressure bearing capacity
Product characteristic
1. The highly effective selective absorption membrane is researched and developed independently, which is applied with an emissivity<0.07 and an absorptivity>0.93.
2. Entire frame is sealed by aluminum alloy, which looks more aesthetic.
3. The products possess more reliable quality due to the application of the ultrasonic plate welding equipments imported.
4. The system is designed with a strong pressure bearing capacity, which can prevent leakage; the testing pressure of the system has reached 1.5Mpa.
5. The high-transmittance ultra clear patterned glass is applied, which makes the collector much safer.
6. Polyurethane foaming technology is applied, which makes the heat preservation performance better, and the back plate using the embossed aluminum sheet, the service life is longer.
