The KRY-48II 48kW split pool heat pump is a professional stadium-grade heating solution tailored for medium-sized commercial swimming pool facilities. Featuring an optimized split-type structure, this system places the condenser and compressor outdoors while installing the high-performance heat exchanger indoors, achieving a scientific zoned layout of core components to maximize operational safety and maintenance convenience. Unlike direct electric or gas heating systems, this commercial swimming pool heater extracts free thermal energy from ambient air—even in low-temperature environments—and transfers it to pool water via a high-efficiency compressor, delivering reliable, energy-efficient heating for year-round pool use. Designed to meet the strict demands of commercial facility managers and business clients, this unit balances precise temperature control, operational safety, and long-term durability, making it ideal for medium-scale commercial pool projects with high performance requirements.

The 48kW split commercial pool heat pump delivers consistent high efficiency in extreme weather, with an applicable operating temperature range from -15℃ to 35℃. It boasts a rated COP of 5.16 under standard conditions (A24/26℃), with every 1 kWh of electricity consumed generating 3-5 kWh of thermal energy. Even in -15℃ low-temperature environments, it maintains a COP of 3, ensuring stable heating performance in winter and supporting uninterrupted year-round operation of commercial pools. This wide temperature adaptability makes it suitable for commercial projects in diverse climate zones.
Equipped with an intelligent digital temperature control system, this stadium constant temperature pool heat pump accurately regulates pool water temperature within the preset range, eliminating the temperature fluctuations common with traditional heating methods. For commercial facilities with strict temperature requirements, it maintains stable water temperature with minimal deviation, meeting event-level and medical-grade standards. In addition, the unit is fitted with multiple safety protection devices, including overload protection, electric leakage protection, and high-temperature protection. With no open flame or direct electric contact with water during operation, it eliminates the explosion and poisoning risks of gas heating, as well as the electric shock hazards of traditional electric heating, ensuring maximum safety for commercial venues.
Built for long-term high-load commercial operation, the core heat exchanger of this commercial pool heater is constructed from high-grade titanium tubes and titanium alloy materials, offering exceptional corrosion resistance and anti-fouling performance to extend the unit’s service life. It features an I-level anti-shock rating and IPV4 waterproof rating, withstanding harsh outdoor installation environments. The unit’s robust construction ensures stable performance even during continuous high-load operation, reducing replacement and maintenance costs for business clients over the equipment’s lifecycle.
