Green no pollutants during use, allows you to experience the living environment of color. SUS304-2B Food Grade Stainless steel water container, fully automatic argon welding technology to ensure that a weld forming, welding firm, with more than enamel liner corrosion resistance. Liner with super anti-corrosion treatment process, magnesium anode rod built device, purify water so that liner life longer. Heat capacity, can withstand the pressure 0.8MPa; insulation layer of polyurethane foam Dow U.S. imports, high pressure seamless one-time full-foam insulation to the liner, to ensure even less heat loss. Water tank with a leading stainless steel coil embedded technology, high efficiency heat transfer, anti-corrosion ability. Heat transfer area matches the golden ratio of the column, so that more energy efficient heat transfer. The latest energy saving technology, intelligent control system, connect solar system, while ensuring the domestic hot water, the whole system can run the whole year for more than 50% energy saving. Need for multiple heat source for heating, heated in a heat source can not meet the demand, you can adopt other auxiliary heating systems to realize annual weather pressure tank used. Economical and practical for split solar hot water centers hung boiler configuration storage devices and other products.
