Detailed introduction
　　Thermal storage tank is a kind of storage tank with thermal insulation medium and thermal insulation layer, which corresponds to single-layer storage tank. The purpose of thermal storage tank is to keep the material temperature unchanged, maintain constant temperature and prevent heat loss. The common thermal storage tanks are hot water tank, cold water tank and thermal storage tank. The thermal storage tank can also be heated by electrified heating device, which can not only keep warm, but also heat. Insulation tank is a vertical or horizontal storage tank, which can be fully insulated, that is, whole or semi-insulated, that is, only part of the insulation. Thermal insulation tank is slightly more complicated than single-layer storage tank in structure. It can keep cold and heat and prevent heat loss. It is a very environmentally friendly storage tank.
