Detailed Description

Flat plate solar collectors

Product features
1.The product adopts copper and aluminium compound core board and anodized coating. Its absorptivity is to be equal or greater than 96% (≥ ),and emissivity is to be equal or less than (≤)18%(85); it has high efficiency, low cost and reliable standard of use.
2. The flat glass is a float glass or toughened glass. Its light transmittance is to be equal or greater than 85%.(≥ 85%)
3. It is usually used in warm-water swimming pools and non-pressuse-type soloar water heater and large-scale project of central solar hot water in southern areas.

4. When the temperature is above 0 , it can be heated directly by water, while when below 0 , antifreeze measures should be taken into account.

flat plate solar collector

1.      Flat-plate collector endothermic body for selective is absorption coatings, and the absorption rate is more than 95%;

2.      pipeline of Collector is brass pipe, good pressure , smooth lines, long flow channel , and it is not easy scaling

3.      Endothermic bodies directly transfer to the working media after decalescence, non-resistance, efficient heat transfer ;

4.      Collector overall only have four interfaces, low-leakage probability, and the cover plate is the tempered glass , high strength

5.      In the addition of same total area , the endothermic effective area of the flat-plate collector is higher than the heat pipe vacuum tube collector;

6.      Flat-plate collector is the entire board, pretty appearance, can perfectly combine with the building, easy to install
