Non-pressure Solar Collector

1) When the temperature of the solar heat collector and water tank reaches the set value, the controller shall make the circulation pump works automatically.
2) Heat-conducting liquid starts to circulate automatically by the circulation pump.
3) The heat exchanger makes the heat-conducting liquid transfers heat to water in the tank.
4)The circulation pump shall be shut automatically, if discrepant temperature of the collector and the water tank does not reach the set value.
5)In case the temperature of the water tank does not reach Tm ax, then starts the auxiliary heating device.

Feature:
1) Higher heat efficiency advanced heat transferring style of the heat pipe.
Excellent selective absorptive coating and perfect combination with high vacuum heat preservation.
2) Wide applicable range: -35~300 degree celsius. As the heat pipe has less heat capacity, it can be started quickly even under cloudy fine day and collect heat effectively. It can work normally even-35 below degree. As no water in the vacuum tube. It can effectively prevent lowing of heat efficiency due to frost cracking or scaling.
3) Each individual tube can work inidependently, and the whole machine can still work if individual tube is damaged. The service life of the heat pipe be longer than 15years.
4) The unique connectin between the heat pipe and the vacuum tube can ensure both sealing and replcace of damaged glass vacuum tube.
5) The insulating layer uses polyurethane bulk bubble and has a good effect of temperature preservation.
6) Seamless and anolized crust of manifold case use alumninum material of high strength with air flow design.
