A heat pump hot water tank is an intelligent hot water device based on heat pump technology. It can use low-temperature heat sources (such as air, groundwater, etc.) to convert low-temperature heat in the environment into high-temperature heat energy, which is then stored in the water tank for use in household life, heating, and other purposes. Heat pump water storage tanks can not only replace traditional water heaters, but also serve as an important component of household heat source heating equipment, with advantages such as high efficiency, energy saving, environmental protection, and safety.
SST adopts a duplex stainless steel cylinder which does not require acid pickling and passivation treatment after welding. Because our automatic weld seam tracking welding equipment has excellent welding performance. In addition, the water tank does not require the addition of magnesium rods, as these duplex material tanks are made of duplex 2205 stainless steel, known for its high resistance to various forms of corrosion, including crevices and stress corrosion, ensuring durability and a longer service life.
