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.
