NULITE commercial pool heat pumps are designed for hotels, resorts, gyms, and public pools, delivering efficient year-round pool temperature control. Featuring advanced heat pump technology, intelligent temperature compensation, and optimized heat exchange, they reduce operating costs while maintaining high efficiency. The intelligent compressor control automatically adjusts output for stable performance, lower energy use, and longer lifespan. With anti-freeze protection and corrosion-resistant components, they operate reliably outdoors in various climates. Combining energy efficiency, precise temperature control, and durable design, NULITE provides a professional solution for modern pool heating.
The commercial air source swimming pool heat pump uses advanced heat exchange technology to absorb free heat from ambient air and transfer it efficiently to pool water. With high COP performance, it helps reduce electricity consumption and operating costs, making it ideal for hotels, gyms, resorts and public swimming pools.
Designed for commercial swimming pool applications, the unit can maintain pool water temperature up to 40°C, creating a comfortable swimming experience in different seasons. Intelligent temperature control allows the system to adjust operation automatically, ensuring stable heating performance and reducing unnecessary energy waste.
Its counter-current design enhances super-cooling and heat exchange efficiency. The small shell-tube gap increases flow velocity for easier oil return, while the large tube diameter prevents deposits and blocking, ensuring long-term reliability.
Efficiently heats pool water by extracting energy from ambient air, maintaining a comfortable swimming temperature during colder seasons. During hot weather, it can also reduce water temperature to provide comfortable swimming conditions in summer. Suitable for year-round pool operation and available on models with heating and cooling function.
Automatically adjusts operation according to ambient temperature changes. Maintains stable pool water temperature while improving energy efficiency and user comfort.
oasting PV DC direct-drive technology, this heat pump lets DC output from the PV array run the compressor directly. No inverters or batteries are needed, so solar power can be used to its full potential. Energy savings can reach 90% in strong sunshine, while the average overall saving stands at roughly 60%. Seamless switching is supported between PV and grid power. The system uses solar power first, and mains electricity automatically fills any power gap.
If a low electricity price signal is received, the heat pump enters boost mode to store heat within the DHW cylinder.
With a normal price signal, it runs at peak efficiency, matching heating output to power consumption.
On a high price signal, operation is time‑limited, with space heating as the sole available function.
Incorporating Modbus RTU protocol, the unit achieves seamless integration with building automation and energy management systems. It enables real-time monitoring of key operating data—water temperatures, compressor status, operating mode, fault codes, and energy consumption—and remote control of on/off, mode switching, temperature setpoints, and special functions such as quiet mode and legionella disinfection. Centralized management of multiple heat pumps is supported through multi-unit networking, and Modbus connectivity enables optimized operation based on electricity price or PV signals. Available data points are set by the manufacturer's register map.
Automatic compensation adjusts water temperature based on ambient conditions, keeping you comfortable year-round.
*Smart Temperature Control
Automatically utilize surplus solar energy to power the heat pump and maximize renewable energy usage.
*Temperature Compensation Technology
Adjusts water temperature based on real-time ambient temperature changes.
*Anti-freeze Protection
Prevents pipe freezing and leakage for reliable outdoor operation in cold weather.
Compressor interchange control logic ensures only the energy required is delivered to the terminals, with up to three compressors switching on or off as needed. This provides comfortable temperatures, extends unit service life, and reduces energy consumption.
NULITE commercial swimming pool heat pumps are equipped with built-in WiFi control, allowing users to manage heating, cooling, and temperature settings remotely via smartphone. Whether you are on-site or away, you can monitor system status, adjust water temperature, and switch operating modes anytime, anywhere – making pool management easier and more efficient.
Combined with high-efficiency heating and cooling performance, intelligent temperature compensation, and reliable anti-freeze protection, this heat pump delivers year-round comfort and lower operating costs for hotels, resorts, fitness centers, and public swimming pools.
Our Smart Cascade Control supports up to 16 interconnected units with intelligent load distribution, delivering highly scalable and energy-efficient year-round cooling and heating for commercial pool water.
Engineered for efficiency, durability, and long-lasting pool comfort, the NULITE commercial swimming pool heat pump features a high-efficiency fan for low-noise, strong airflow, hydrophilic aluminum fins for anti-corrosion and high heat exchange efficiency, and standard water inlet/outlet connections for reliable, durable, and stable long-term operation.
NULITE commercial swimming pool heat pumps are built with high-quality core components to ensure reliable, efficient, and long-lasting performance: the world-famous EEV (electronic expansion valve) precisely controls refrigerant flow through PID technology to reduce energy consumption; the compressors switch on or off according to actual energy demand for reliable and easy operation; the hydrophilic coating air exchanger provides strong anti-corrosion performance and high heat exchange efficiency; and the patented C&S heat exchanger with strong counter-current design improves both efficiency and reliability of the unit.
