1.color steel material,Cu-AL-SS coating 2.ISO,CCC,CE 3.high efficient,heat quickly,72 hours for hot water 4.5 years warranty

Techinical Parameters:

Vacuum tube:

    1.Material:1.6mm thickness borosilicate glass 3.3,AL-N-AL or Cu-AL-SS coating

    2.Tube pressure:≤5×10-3pa;Absorptance≥0.91

Water Tank:

    1.Inner tank:0.5mm thickness SS304 stainless steel

    2.Outer tank:0.4mm thickness SS202 stainless steel or color steel

    3.Absorbing layer: high-pressure polyurethane foam with 55mm thickness

    4.foaming density:35g/cm3;closed-cell foam rate:95%

    5.capactiy: 150L,240L,300L,360L

Bracket:

    1. galvanized steel or aluminum alloy with 1.5mm thickness;

    2.Angle of stand:18°,20°,38°,45°

Working Principle:

There is water in the vacuum tubes and free to flow into tanks. When the water in the tubes is heated by the sun's rays firstly, this makes water in the tubes lighter. Therefore, the cold water in the tank move downwards and hotter water move upside into the top of the tank. It is an open circuit since the air vent and the overflow pipe is open to the air.

Features:

1. Easy installation, both on the inclined and flat roof

2. supply the hot water in 72 hours

3. wind-resistance,snow resistance for 15 mm

4. 15 years using life for vacuum tubes

5. energy-saving, efficient, heat quickly.
