Sell FORMAL Chaofan Series Solar Water Heater

Description

New generation of solar water heater has applied nanometer technology to the vacuum tube, so it has greatly improved its solar absorption ability up to *8%. The unique carbon coating layer is firmer than the traditional AL-N/AL coating layer, for the stability of carbon. It is highly weathering resistant and the coating layer can stay longer. The Chaofan series has applied the American technology and technique, strictly controlled every process from cleaning to exhaustion, to make the degree of vacuum reach ***3Pa for less emissivity. The vacuum tube is made by concentrated borosilicate glass 3.3, so the vacuum tube is of low expansion coefficient and high intensity. The vacuum tube could afford the full-face impact of *5mm hailstone. The inner tank is under three years warranty period. The Chaofan series has applied the nontoxic food grade SUS**4 stainless steel to the inner tank. The professional welding and the top-ranking quality control system ensure the long service of FORMAL solar water heater.
