buying guide from which several parts?
By coating with a high absorption rate (greater than 93%), low-emissivity (less than 6%) of the advantages, so much enhanced the efficiency of the solar water heater collector. use high-quality 430 stainless steel plate bracket processing of shape, appearance, solid and reliable. But the material is stainless steel, and the complex manufacturing processes, so the cost is high, labor-intensive.
Storage tank for the solar water heater installations, which by the liner, insulation, shell composition. Water tank adopts imported 304 stainless steel plate made by automatic argon arc welding process, due to a low carbon 304 stainless steel, so welding of high quality, easy to rust; 45mm polyurethane foam to form the insulation layer as a whole to ensure thermal efficiency of solar water heaters greater than 50%; tank shell color spray, high strength, freeze-drying by air proved: the local temperature in the tank up to 200 ° C in the case, not because the polyurethane shell expansion and deformation Splitting, and average temperature of -15 ° C to low temperatures, the cold compression of polyurethane will not affect the color plate housing.
