The magnetic levitation inverter water-cooled chiller uses advanced oil-free compressor technology to reduce mechanical friction, improve operating efficiency and lower maintenance requirements. With no oil circulation system, the unit helps keep the heat exchanger cleaner and supports stable long-term performance for demanding commercial HVAC projects.
Equipped with intelligent inverter control, the chiller can automatically adjust compressor speed according to real-time cooling demand. This helps improve part-load efficiency, reduce unnecessary power consumption and deliver reliable chilled water output. It is ideal for buildings with changing cooling loads throughout the day.
Designed for central air conditioning systems, the unit provides continuous and stable chilled water for hotels, shopping malls, office buildings, hospitals, factories and data centers. Its water-cooled design improves heat exchange efficiency and supports reliable operation in large-scale commercial and industrial cooling applications.
Magnetic levitation technology allows the compressor rotor to operate without direct mechanical contact, greatly reducing vibration and operating noise. This makes the chiller suitable for noise-sensitive applications such as hotels, hospitals, office towers and high-end commercial buildings that require quiet and comfortable indoor environments.
The chiller can be equipped with intelligent control functions for system monitoring, fault protection and precise temperature adjustment. Multiple protection features help improve operating safety, reduce downtime and simplify daily management. It offers a dependable cooling solution for projects that require efficiency, stability and long service life.
*Compression Components
The compressor consists of first-stage and second-stage impellers, a rotor, a stator, and a high-speed permanent magnet synchronous motor. The two-stage impellers handle initial and final refrigerant compression, while the rotor and stator generate electromagnetic drive force for smooth high-speed operation.
*Magnetic Bearing System
Front and rear radial magnetic bearings support the rotor at both ends through magnetic levitation, eliminating mechanical friction, wear, vibration, and noise. The axial magnetic bearing controls the rotor’s axial position to ensure safe and reliable operation.
*Power Core
The high-speed permanent magnet synchronous motor directly drives the rotor with high efficiency and power density, serving as the power core of the compressor.he high-speed permanent magnet synchronous motor directly drives the rotor with high efficiency and power density, serving as the power core of the compressor.
Magnetic levitation bearings eliminate mechanical contact, resulting in minimal vibration and noise, which creates a quiet and comfortable operating environment for the equipment. This makes the NULITE Magnetic Levitation Inverter Water-Cooled Chiller ideal for noise-sensitive applications such as hospitals, hotels, office buildings, and high-end commercial spaces, where low vibration protects surrounding structures, extends equipment life, and ensures a peaceful atmosphere for occupants while reducing wear and maintenance needs for long-term reliable performance.
The NULITE Magnetic Levitation Inverter Water-Cooled Chiller features three core technologies for superior performance: the blue Oil-Free Magnetic Compressor delivers zero friction, ultra-low vibration, and high efficiency; the Smart PLC Touch Screen on the gray control cabinet provides real-time parameter monitoring and inverter control; and the High-Efficiency Shell & Tube Vessel ensures optimized heat transfer and robust pressure resistance. Together, these components enable the chiller to achieve efficient, intelligent, and stable operation.
Magnetic Levitation Inverter Water-Cooled Chiller. – Front & Rear View
Front View– Clean & Durable Design
On the left side of the front panel is a gray electrical control cabinet equipped with a color LCD touchscreen for real-time monitoring and parameter setting, with a red emergency stop button below the screen for safety. To the right of the cabinet is the blue magnetic levitation centrifugal compressor, connected to black suction piping above in a compact layout. Below is the circular end face of the large black heat exchanger, featuring flanged bolt connections, supported by a sturdy black steel channel base, giving the unit a professional and solid industrial appearance.
Rear View
The side clearly shows the water-side piping system, including the inlet/outlet water flange connections extending from the black cylinder, along with valves, pressure gauges, and sensors, forming a complete cooling water and chilled water circulation loop. The unit adopts a dual-cylinder horizontal layout, with the evaporator and condenser arranged side by side, connected above by compressor discharge piping and electronic expansion valve refrigerant lines. The back is equipped with cable entry holes for main power and control wiring. Ample space is reserved on the sides and back for pipe inspection, sensor calibration, and electrical maintenance, making the overall structure compact and easy to service.
Site Preparation & Unit Positioning
Choose a well-ventilated outdoor location with a stable foundation and enough service space around the unit. Keep the installation area clean, dry, and easy to access for maintenance. Make sure the position is suitable for pool water piping and power connection. Place the commercial air source pool heat pump on a solid base and fix it securely. Ensure the unit is level to support stable operation, and leave enough clearance for airflow intake and discharge to maintain efficient heat exchange performance.
Water Pipe Connection, Electrical Wiring & System Start-Up
Connect the unit to the pool circulation system per the installation diagram. Install inlet/outlet pipes correctly, add valves, a filter, and a circulation pump if needed, and check all joints for leaks. Connect power and control wiring per the manual and local standards; electrical work must be done by a qualified technician. After installation, fill with water, remove air, check water flow, power, and settings, then run a full test to confirm stable heating and correct temperature control.
