Core Advantages Introduction
1. Precision-engineered high-temperature enamel inner liner, providing superior corrosion resistance and an exceptionally long service life.
The Air Source External Coil Heat Exchange Tank's inner liner is made of 2.0mm thick enamel-coated steel plate. Both the inner and outer walls are coated with a nano-ceramic enamel layer via high-temperature electrostatic spraying and then sintered at temperatures above 850℃. This ensures the enamel layer is tightly fused to the steel plate substrate, resulting in a smooth, dense coating and a stable, robust structure. The inner liner possesses exceptional resistance to acids, alkalis, scale, and chloride ion corrosion, making it highly adaptable to hard water and complex coastal environments with high salt spray. Its service life is 10-15 years. Furthermore, the tank comes standard with a long-lasting, high-purity magnesium rod, forming a dual anti-corrosion protection system for the inner liner, further resisting water erosion and significantly extending the overall lifespan of the unit.
2. External coil double isolation structure, ensuring maximum safety and worry-free clean water supply.
The Air Source External Coil Heat Exchange Tank employs a unique external microchannel heat exchange coil design, achieving complete physical isolation between the heat exchange coil and domestic water . This eliminates problems such as coil leakage, refrigerant cross-contamination of the water, and water quality contamination due to pipe corrosion at the source. It truly achieves complete separation of water and electricity throughout the entire process, completely avoiding the safety hazards of electric leakage, ensuring safe drinking water for the elderly and children. Domestic hot water only comes into contact with the pure enamel inner tank, preventing the leaching of heavy metals and contamination from pipe impurities, resulting in clean and healthy water quality and comprehensively protecting the safety of the whole family's bathing and domestic water use.
3. High-density integrated foam insulation provides long-lasting heat retention and outstanding energy-saving performance.
The Air Source External Coil Heat Exchange Tank utilizes a high-density polyurethane integral high-pressure foaming process , resulting in a uniform and dense insulation layer with no internal gaps or seams. Its 360° fully enclosed inner tank provides excellent heat retention. The tank experiences minimal water temperature drop over 24 hours, effectively locking in heat and significantly reducing natural heat loss. This minimizes the need for repeated start-stop cycles of the heat pump unit, leading to more energy-efficient operation, lower long-term water costs, and a stable, comfortable water temperature maintained around the clock.
4. Smooth enamel inner wall, inhibits and resists scale buildup, ensuring long-term stable heat exchange efficiency.
The inner tank has an extremely smooth and dense enamel glaze, making it difficult for scale to adhere and accumulate in the water. This slows down scale formation at the source, and with long-term use, the inner tank will not accumulate or clog. The heat exchange efficiency will not decrease, and the heating will be stable and efficient all year round. There is no need for frequent descaling and cleaning, and it will maintain the heat exchange performance of a brand-new unit for a long time.
5. Standard pressurized structure ensures stable water supply throughout the entire area, providing comfortable and consistent water output.
The entire unit adopts a compliant pressure-bearing design and can stably withstand the municipal tap water pressure of 0.6~0.7MPa. The pipeline water supply is highly stable, and the water output remains strong and stable even when multiple points are in use at the same time. The water temperature is constant and does not fluctuate between hot and cold, making the bathing water experience comfortable and perfectly suitable for multi-point water supply scenarios throughout the house.
6. The interface is comprehensive and well-organized, making maintenance convenient and worry-free, and it has excellent adaptability.
The water tank is equipped with a complete set of standardized multi-functional interfaces, including a temperature sensing interface, return water inlet, cold water inlet, medium inlet and outlet, and a dedicated drain interface. The piping layout is clear and reasonable, allowing for quick connection to the air source heat pump unit, safety valve, mixing valve, and other complete system accessories, making installation convenient. The dedicated drain port at the bottom allows for regular drainage and cleaning of scale. Furthermore, the external coil structure eliminates the risk of internal water circuit blockage, making daily maintenance simple and virtually maintenance-free, ensuring worry-free and effortless use in the long run.
