new style divided pressurized solar collector water heater  

The split solar water heating is an active system, because it uses a pump with a controller to circulate the fluid between solar collector and the storage tank, tank and solar collector are separate, while the collector is integrated in to the roof of the building, the tank and the pump station can installed anywhere of the building.

Vacuum tube: three layer evacuated tube

 The vacuum tube of our solar water heater has the high absorption rate and low emission rate,

the absorption rate is 0.91-0.93 (AM1.5)

the emission rate is 0.05-0.075 (80±5)

vacuum tightness is P<5.0*0.0001Pa

idle sunning property parameters is Y=220-260./KW

the average heat loss coefficient is Ult=0.6-0.7W(.)

1) This collector tube adopts magnetron sputtering coating technology

2)  Coating: Cu/Ss-Aln/Aln high efficient selective absorptive coating and vacuum heat insulation could get higher heat and have high performance of absorptance and low reflection ratio and performing a strong heating ability.

3)tube life: more than 15 years.

Our company is a manufacturer of  solar collectors and solar water heaters in China .We have ISO certification and some other related certifications.We always give our customers best price and good quality! We sincerely hope you will be my next business friends.
