Feature of the main components
Liner of the water tank: better material and extensive use. Liner with high quality ensures the quality of the water heater. Keyu solar water heater adopts special food-grade stainless steel USU304-2B, thickness of this stainless steel is more than 0.5 mm. Increase intensity, weld by argon-arc welding, the life of the water heater is more than 20 years. Adopts high quality food grade silica gel, it can effect firm airproof and longer life.
Full glass double vacuum solar heat collecting pipe: Particular Sino-Australia technology--Double target magnetic control spay plating solar heat collecting pipe of full glass. Bear high temperature, resist frost, high heat efficiency, long life.
Insulation layer: super insulation structure of polyurethane froth under high pressure at site. It can make the proportion of polyurethane reasonable, froth more equably and better performance of insulation. Remain hot water 100 hours.
We can not only supply the whole solar water heater but also can design and build the factory.
