Working Principle:
1.When the temperature of the panel collector reaches the set valve, the controller shall start the
circulation pump automatically.
2.The circulation pump makes heat-conducting liquid circulate
automatically.
3.The heat-conducting liquid transfer heat to water by the heat
exchanger in the water tank. 4.In case the temperature of the collector dose not reach the set
valve, the circulation pump shall be shut automatically 5.In case the temperature of the water tank dose not reach T-max,
then start the auxiliary heating device.
Specification of flat plate solar collector:
1) Low iron textured tempered glass(3.2mm thickness)offers the best
capability of durability, strength.
2) Tinox blue titanium or black chrome coating have very high
absoption rate to ensure the high efficiency.
3) Whole-plate ultrasonic welding technology makes the flate plate
solar collector more beautiful, efficient and durable.
4) Special Anodized aluminum alloy frame to ensure handsome
appearance and can accept high pressure without leakage.
