Tube structure | Borosilicate 3.3 glass |
External pipe diameter and thickness | Φ=47±0.7mm &=1.6mm Φ=58±0.7mm &=1.6mm Φ=70±0.7mm &=1.6mm |
Internal pipe diameter and thickness | Φ=37±0.7mm &=1.6mm Φ=47±0.7mm &=1.6mm Φ=58±0.7mm &=1.6mm |
Tube lenghth | from 1.2 to 2.1 |
Sediment method | Three Targets magnetron sputtering plating |
Absorptivity | 0.93-0.96 |
Emittance | <=6.0%(75-80°C) |
Stagnation parameter | 240~260 |
Average heat loss | <=0.6 |
Advantage of us :
1). we adept the advanced magnetron sputtering plating to make sure gain high absorptivity and low emittance.
2) We used Stainless steel ion instead of Aluminum Whiich can endurehight tempreture.
3).the Interference film changed little in high tempreture.
4).Highly efficient zbsorber of high performance with daily average effciency over 40%-50%.
5).Start up quickly heat pipe transfer the heat energy into the storage tank in one condition.
6).With stand pressure of 0.6Mpa,can be connected directly with city water pipe.
7).Highly efficient insulation with polyurethane foam.
8).Can be used all year round even in the cold weather.
9).Automatically controlled.
10).For both flat roof and slope roof.
