Flat Plate Solar Water Heater Specification

1.The Flat Plate Solar Collector is some kind of the metal pipe-plate style structure, high heat effect, high hot water produced, anti-insolate, water heater in the copper pipe, reliable quality, free maintenance, can stay for 15 years. Slinky appearance, easy installation, not easy to be destroyed. High absorption efficiency: >=92%, Low Emission :< =10%, Average heat Efficiency: >=55%.

2.Specification: 2m*1m*70mm/80mm/90mm, 2m*1m flat solar collector, the water can rise to 55°C in the Sun day 75-140kg/m2.

3. Material of core: Copper and aluminum unified core, or all copper core, heat pipe diameter: 22mm/25mm. Few welding line, high intension, and strong pressure resistance.

4. Coating: Anode oxidation film, selective paint, or titanium-coating.

5. Tempered glass: High transmittance, good heat preservation, film and long service life, thickness is 4mm or 5mm.

6. Work pressure: 0-1.2Mpa

7. Beautiful outlook and more high anti-corrosion. Operated automatically, stable performance, little maintenance, can stay for nearly 20 years

8. Special preservation: Glass wool/ high dense polyurethane foam.

Working principle

Sunlight passes through the glazing and strikes the absorber plate, which heats up, changing solar energy into heat energy. The heat is transferred to liquid passing through pipes attached to the absorber plate. Absorber plates are commonly painted with "selective coatings," which absorb and retain heat better than ordinary black paint. Absorber plates are usually made of copper or aluminum because the metal is a good heat conductor. Copper is more expensive, but is a better conductor and less prone to corrosion than aluminum. In locations with average available solar energy, flat plate collectors are sized approximately one-half- to one-square foot per gallon of one-day's hot water use.

Structure

The flat panel are simple, efficient design, durable and economical for application of solar water heating system of residential, hotel, school ,commercial and industrial constructions.

Absorber: Made of all copper or aluminum copper complex absorber plate.

Selective coating: selective black chrome, magenetic sputtering, and anodized electrophoresis available.

Ultrasonic welding technology to joint the tube and fin together perfectly.
