Pressurized Integrated Vacuum Tube Solar Water Heater

Features:

· The copper pipe inside the vacuum tube could quickly transfer the heat into the water tank through heat conduction medium.

· The system can endure the max pressure up to 0.6Mpa.

· There is no water in the vacuum tube.It can endure the freezing -35 degree centigrade.

· The vacuum tube can endure the 25mm hailstone.

· Heat pipe has the functions of one-way heat transfer, small thermal capacity, low start-up temperature.

· For inner tank, we adopt high frequent melting technology.

· It can directly connect with tap water system.

· It eliminates the low heat efficiency problem caused by fur.

Specification:

· Inner tank: SUS 304-2B food grade stainless steel 1.2mm-1.5mm

· Outer tank: SUS 304-BA stainless steel 0.31mm-0.41mm

· Bracket: Galvanized steel with powder painting

· Heat insulation layer: 55-60mm imported PU

· Vacuum tube: high borosilicate 3.3 ; coating:ALN/ALN-SSCU.

Working Principle：

The pressurized water tank has no exhaust hole, therefore, it must bear the pressure came from tap water and hot water. When use, the hot water comes out because of water pressure. Vacuum tube absorbs solar energy, and conductive copper pipe transfers the heat into the pressurized water tank. In this case, the water inside the tank becomes hot. No water in the heat pipe makes the whole system could bear pressure.
