Non Pressurized solar water heater :
1. Inner tank:
1).Materials:SUS304/2B, food grade stainless steel;
2).Welding procedure: completely auto argon arc welding;
3)Cover of inner tanks: curved outwards to bear higher pressure
2. Outer tank
1).Materials: Stainless steel, food grade stainless steel
2)Production procedure: stainless steel outer shell, sheet are jointed-up after crimping;
3.Insulation layer
1).Materials: polyurethane , environmentally friendly
2).procedure: Using CNC constant temperature, constant pressure quantitative foaming, curing processing, thick insulation layer, ensure the quality more close, well-balanced, insulation more abiding.
4. Brackets
Materials: stainless steel
5.Evacuated tubes
1).Three-target all-glass vacuum heat collection tube (coating: CU/SS-ALN(H)/SS-ALN(L)/ALN )
2).Single target All-glass vacuum heat collection tube ( coating: AL/AL-ALN(H)/AL-ALN(L)/ALN )
The selective coating on the inner cover of the evacuated tubes converts solar energy into heat energy and water in evacuated tubes the heat. When temperature rises along with density drops, and weight goes down, hot water will go up to exchange with cold water in tank. In this way, the temperature of the water in tank goes up.
