Basic Specification

Solar heater description 
1. All machine mental parts is stainless steel and galvanized steel
2. Inner tank: Φ380mm/SUS304-2B/1.2mm. Outer tank: Φ480mm/Galvanized steel/0.35mm
3. It use 50mm of high density polyurethane foam for insulation layer. Heat preservation: 72hours
4. Vacuum tube: 58x1800mm 1.6mm or 2.2mmthickness ALN-SS-CU coating
5. Copper heat pipe inside the vacuum tube, have high conduction performance
6. The bracket is in line with structural mechanics, very stable and solidly build. Dual-purpose for both flat and inclined roof.
7. No water inside the evacuated tubes, the solar water heater can still in service even with several tubes breakage
8. Can be used all year even in the cold climate area
 
Solar heater 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. Can be used all year round in the cold climate

 Working Principle
 
The selective coating on the inner cover of the evacuated tubes converts solar energy into heat energy and transfers heat to the heat pipes 

by aluminum fins, the liquid in the heat pipe changes into vapour which rises to the condenser. The heat then passes through the heat 

exchanger and the vapour becomes liquid, returning to the base of the heat pipe. The heat conducts to the heat transfer liquid(anti-freezing 

liquid or water ) via a copper pipe. This transference of heat into the liquid creates a continuous circulation as long as the collector is heated by 

the sun.

Feature of Full Hard Galvalume Steel Coil:

1) Full Hard Galvalume Steel is composed of 55% aluminum, 43.5% zinc and 1.5% Silicon.

2) Full Hard Galvalume steel is formable, weldable and paintable.

3) Full Hard Galvalume steel has superior corrosion resistance in the most atmospheric conditions. This is achieved through the combination of the sacrificial protection of the zinc and the barrier protection of the aluminum.

4) Full Hard Galvalume Steel coating out-perform galvanized coating from 2-6 times than hot dip galvanized steel.
