Working Principle:
An active, closed-loop system heats a heat-transfer fluid (such as water or antifreeze) in the collector and uses a heat exchanger to transfer the heat to the household water.
Operation of the system is very simple:
1.Solar Absorption: Solar radiation is absorbed by the evacuated tubes and converted into heat.
2.Solar Heat Transfer: Heat pipes conduct the heat from within the solar tube up to the header.
3.Solar Energy Storage: Water is circulated through the header, via intermittent pump cycling. Each time the water circulates through the header the temperatures is raised by 5-10oC / 9-18oF. Throughout the day, the water in the storage tank is gradually heated.
Features:
1.Internationally certified product.
2.Reliable,efficient,twin-glass evacuated tubes with copper heat pipes for rapid heat transfer,no water enter into the tube,can be used in cold area.
3.Easy plug-in installation and maintenance.
4.Suitable for mains pressure water (up to 8 bar/ 11 psi).
5.Corrosion resistent silver brazed copper header.
6.Stable solar conversion throughout the day (tubes passively track the sun)
7. Perfect solar collector for domestic solar water heater systems.
8.Ideal for big project like swimming pool,school,hotel..
