Split-pressure Solar Water Heater - FR-FT-200

Working Principle:

The key of this system is solar heat pipe collector, which consist of solar vacuum tube, heat pipe, manifold,frame etc. Heat pipe has some medium inside, When solar vacuum tube absorb heat energy from sun, then transmit it to heat pipe , the liquid medium of the bottom of heat pipe become vapour, then rise up to the top, cooled by cold water then go down to the bottom of heat pipe,This is circulation of solar heat pipe collector. This complete system is connected by pipe(copper pipe). There are two temperature sensors in solar heat pipe collector and water tank, For example, We set the temperature difference is 10 degree, when the water temperature rise, and the temperature difference between solar heat pipe collector and water tank exceed the set value, The controller inside solar working station will start the circulation pump, the cold water will cool the solar heat pipe collector, and heat the water inside water tank by exchanger inside water tank, when the temperature difference is down under the set value, The controller will stop the circulation. It just is circulation process. Via one day working, the water temperature of water tank can arrive in 50~95 degree, Then we can use the hot water inside the water tank!

Split pressurized solar water heater,separated pressure solar water heater system

Split pressurized solar water heater is composed of heat pipe, evacuated tube solar collector,

pump station (including circulation pump, controller, expansion vessel, pressure gauge, sensors etc)

and pressurized water tank.

Working principle:
When the temperature of the heat collector reaches the set value,

the controller shall start the circulation pump automatically. The circulation pump makes heat-conducting liquid circulate automatically. The heat-conducting liquid transfers heat to water via heat exchanger inside the water tank.

In case the temperature of the water tank does not reach the set value, then the auxiliary heating device will be started.

In case the temperature of the circulation pump does not reach the set value, the circulation pump shall be shut automatically.

Features:
1.Collectors are separated from the storage tank, so the tank can be put anywhere around the house.

2.The collectors can be put on the inclined roof or flat place

3.Module structure, easy combination, harmony with the building perfectly
4.Intelligent control and automatic operation
5.No worry about being frozen because there is no water running inside the tubes when working
6.The system controller will start the at the set value so as to prevent the system from freezing
7.Workable at anytime and enjoyable multifunction
8.Hot water center for bathing, washing and domestic heating
