SMMT high selective solar absorber "Thermal Collector is manufactured by advanced PVD coating devices, which achieve absorptive rate up to 95% and heat emission lower than 5%. It is also optimized to the wavelengths of sunlight with the high intensity to bring the maximum heating performance.
SMMT high selective solar absorber "Thermal Collector" is made with continuous air-to-air producing vacuum coating equipment, which give us the possibility to coat with high efficiency and speed. It combines sputter process and electron beam technology to form the selective absorber layers on metal strips.
This kind of PVD still achieves both the high quality of layers and the environment protection.
SMMT will be a reliable long-term cooperation partner for flat plate solar water heater and evacuate tube water heater supplier.
