4. Insulating layer: 50 to 60mm high pressure polyurethane foam
5. Bracket: premium cold roll bracket stainless steel screw
6. Vacuum tube: 3.3 high borosilicate glass (47/58mm)
7. The vacuum tube of our solar water heater has the high absorption rate and low emission rate, the absorption rate is 0.90 to 0.93 (AM1.5)
8. The emission rate is 0.05 to 0.075 (80± 5)
9. Vacuum tightness is P ≤ 5.0 x 0.0001Pa
10. Idle sunning property parameters is Y = 220 to 260/kW
11. The average heat loss coefficient is Ult = 0.6 to 0.7W (.)
12. It means the temperature in the water tank is ranging from 50 to 95
13. Type: 16, 18, 20, 24, 26, 28 and 30 tubes
14. Capacity: 130 to 228L
15. Characteristics:
    1. Best angle of stand makes the heat efficiency is very high
    2. All of the inner tank is produced by high-frequency ring welding or argon arc welding, which is very durable; high density
    3. The insulating layer made of high pressure polyurethane foamed
    4. The water inlet or out let can be set up as your asked
    5. Intelligent controller or electrical heat element can be chosen for this system according to your requirement
    6. Advanced technology, which can dispose of scale, bacteria and prevent electricity
    7. Environmental friendly
