The key accessory of every solar collectors is the solar absorber. Its efficiency is given by a high absorpitve and low emission rate.


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 producting vacuum coating equipment, which give us the possiblity 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 patner for flat plate solar water heater and evacuate tube water heater supplier.
