The STE-PSS Series, in streamline closed circuit systems which are recommended for frost prone and poor water quality situations. Antifreeze fluid is used to circulate through the collectors. The heat collected from the panels is transferred from the fluid pipes to the water tank by a heat exchanger. The circulator is regulated by a control unit on the water heater. This ensures the optimum use of the sun's free energy.
Features:
1) The solar collector and water tank can be placed separately, easy to install, easy for building integration
2) The water tank is indirect tank with a single coil exchanger, completely solve the problem of collector in freezing and harsh water area
3) Reliable electric back-up with protection against dry heating and thermal cut-out
4) With quality flat solar collector and enamel water tank for long service life
5) Polyurethane insulation with good heat reservation
6) Totally metal flow channels made by copper
7) Low failure rate and easy maintenance
8) Easy operation and intelligent control
