The direct filtration water dispenser adopts reverse osmosis filtration membrane. Through the concentration and filtration of water quality, various impurities such as residual chlorine, sediment, rust, lead and bacteria can be well removed, but the beneficial substances in water-natural minerals-will not be removed, which can well ensure the demand for healthy substances of human body. Energy-saving water boiler is also called energy-saving water boiler and energy-saving water boiler. Different places have different names, including full boiling water type and warm water type, but they all require energy saving, health and environmental protection. Advanced steam heat recovery technology, heat exchange technology, stepped heating technology and high-tech insulation materials are adopted to maximize energy saving, health and environmental protection, and prevent the occurrence of boiling water and yin and yang water. Widely used in schools, hotels, hospitals, factories, stations, airports, government agencies and other public places, bringing convenience to users.
