China pressurized compact solar water heater

 Integrative pressurized solar water heater

 1. the products use super heat condition pipe and has a good effect of heat exchange.

 2. the insulation layers use the up-to-date technology and has a good effect of temperature preservation which allows the water to stay warm for about 90 hours.

 3. Superior heat-preservation ensured by one-off molding polyurethane foam with thickness 55-60mm.

 4. stable and reliable performance, well wind resistance.

 5. meet the mankind healthy bath standard,the material of inner tank is SUS304-2B stainless steel plate, the silica gel ring sealing has a long life against the erosion and it do no harm to health.

Working principle

The vacuum tubes absorb and convert solar energy into thermal energy, then transfer to the central heat

pipe via the aluminum fins. The heat pipes have tiny amount of purified water sealed inside at depressurized condition. When heated, the water inside the heat pipes vaporizes at low temperature (about 30°C), the vapor rises to the condenser and heat energy is conducted to water (inside the tank). When vapor is cooled down and becomes condensate, it falls to the bottom of heat pipe. By continuously circulating in this way, heat is carried from outside to the water inside the tank.

Advantages

1) Adopts the best conduction performance metal- heat pipe (copper).

2) Start up quickly, heat pipe transfer the heat energy into the storage tank in one direction

3) No water inside the evacuated tubes, the solar water heater can still in service even with several tubes breakage

4) No water in the vacuum tubes eradicate the incrustation scale, thus keeping them running in high efficiency

5) No water in the vacuum tubes eradicate the frost cleft even in Jack Frost condition

6) Can be used all year round in the cold climate

7) No maintenance

This type of solar water heater works with high pressure, so do the water it pressurized.

It uses the heat pipe to conduct the heat energy, it can work rapidly.

Because of no water in the vacuum tube, so there will not tube breakage in the winter.

Each vacuum tube can work alone, so it can still operate in the event of occasional tube breakage.
