unpressurized solar water heater

Unpressurized solar water heater:

Solar water heater(solar key mark and SRCC certificate); Advanced argon welding technic; Advanced technology

Solar water heater features:

The system of solar water heater relies on a natural principleThermosiphon. The key important point of these systems is that : the storage tank is always located higher than the collector.

As the suns rays hit the all-glass evacuated solar collector tubes, the temperature of the water in the tubes rises making it less denser or lighter , and hot and lighter water naturally moves up to the top of collector and through the evacuated collector tube convert to the storage tank . this makes the colder and heavier water . In water tank moves down to the bottom of the collector, that continuous displacement occurs

naturally . so the users can get the hot water from the tank. The system of solar water heater is an open circuit non-pressure system. By the air vent valve on the top of the storage cylinder and the over flow pipe in the bottom it maintains open to the air.

Material:

Inner tank: imported 3042B food grade stainless steel, thickness is 0.5mm

Outer tank: imported nacre white armor plate or stainless steel

Insulating layer:50mm-60mm high pressure polyurethane foamed

Bracket: premium cold roll bracket stainless steel screw

Vacuum tube: 3.3 high borosilicate glass

The vacuum tube of our solar water heater has the high absorption rate and low emission rate,

The absorption rate is 0.90---0.93(AM1.5)

The emission rate is 0.05---0.075(80±5)

Characteristic

1)       Best angle of stand makes the heat efficiency is very high

2)        All of the inner tank is produced by high-frequency ring welding or argon arc welding, which is very durable;

High density

3)       The insulating layer made of high pressure polyurethane foamed

4)        The water inlet or out let can be set up as your asked

5)        Intelligent controller or electrical heat element can be choosed for this system according to your requirement

6)        Advanced technology, which can dispose of scale, bacteria and prevent electricity

7)        Environmental friendly
