What is thermosiphon system?

Thermosiphon system is passive with a solar hot water storage tank mounted higher than the solar collector. They rely on passive natural convection where cold water falls, moving hot water to the storage reservoir at the top, that means cold water pushes up the hot water. The advantage of this system is that there are no moving parts, which means you almost don’t need maintenance.

The features of the solar tank:

1. The inner tank is made of stainless steel 304, with good tensile performance, can bear high pressure.

2. Foaming insulation material: polyurethane material, fluorine- free, environmental protection, excellent thermal insulation effect.

3. Color steel plate: various colors available, high strength, corrosion resistance, no fading and no paint stripping.

4. Coil: high quality 316L stainless steel pipe, can withstand 12.5mpa pressure, ultra-high pressure bearing capacity, ultra- high corrosion resistance, double- layer and three-layer winding design, excellent heat exchange effect.

The features of the solar collectors:

1. Glass- low iron, cloth, tempered glass.
3.2mm high-quality low iron tempered glass: the "core" with full spectrum transmittance of 91.7% and no fading.

2 Black chrome selective coating , high efficiency.

3. Heat transfer structure- optimizing structure and strengthening heat transfer.
All copper tube runner design, pollution-free, high pressure bearing, good heat transfer performance.

4. Mechanical properties: weather resistance, corrosion resistance and pressure resistance
Weather resistance: the coating is stable and suitable for various adverse weather conditions:
Corrosion resistance: high temperature (480c) oxidation / hardening treatment on the alloy surface makes it has better corrosion resistance and pressure resistance than copper: the pressure bearing design and welding process of 35PA flow channel structure ensure the service life of the collector for 30 years:

5.Thermal performance - high efficiency and low heat loss.
