Kingfit Magnetic Bearing Centrifugal Water Chiller is a type of cooling system that uses centrifugal force to circulate water through a refrigeration cycle to remove heat from a building or process. The chiller has a centrifugal compressor that uses a combination of magnetic bearings and an electric motor to spin the compressor impeller, which accelerates the refrigerant gas and compresses it to a high pressure.

The magnetic bearings are used to levitate the compressor shaft, which eliminates the need for traditional lubrication systems and reduces friction and wear on the moving parts of the compressor. This results in increased energy efficiency, reduced maintenance, and longer lifespan of the chiller.

The water is cooled as it flows through the heat exchanger, which transfers the heat from the water to the refrigerant gas. The refrigerant gas then circulates through the compressor, condenser, expansion valve, and evaporator, completing the refrigeration cycle.

Kingfit Magnetic Bearing Centrifugal Water Chiller is known for its high energy efficiency, reliability, and low maintenance requirements. It is commonly used in large commercial and industrial applications, such as data centers, hospitals, universities, and manufacturing facilities, where a reliable and efficient cooling system is required to maintain a consistent temperature and humidity level.


Magnetic Bearings: Magnetic bearings support the rotating components of the chiller, eliminating the need for traditional mechanical bearings. This reduces friction and increases efficiency.

High Efficiency: Magnetic bearing centrifugal water chillers are highly efficient, providing significant energy savings compared to other cooling systems. They can operate at high speeds and deliver precise temperature control.

Environmentally Friendly: These chillers use water as a refrigerant, which is environmentally friendly and does not contribute to ozone depletion. They also do not use any harmful chemicals that can harm the environment.

Low noise levels: Magnetic bearing technology and other design features help reduce noise levels. This is important for facilities where noise levels need to be kept to a minimum.

Reliability: Magnetic bearing chillers have fewer moving parts, reducing the risk of mechanical failure and increasing overall system reliability. This also means that maintenance costs are lower.

Compact design: The chiller's compact design saves space and allows for flexible installation in different locations.

Scalability: Magnetic bearing centrifugal water chillers are available in a wide range of sizes, making them suitable for a variety of applications. They can be customized to meet specific needs and requirements.

Integrated Controls: Magnetic bearing centrifugal water chillers come with advanced controls that provide accurate temperature and pressure regulation. They can also be connected to building management systems for remote monitoring and control.

Easy maintenance: The use of magnetic bearings eliminates the need for lubrication and other maintenance tasks associated with traditional bearings. This reduces maintenance costs and downtime.

Energy Recovery: Some magnetic bearing centrifugal water chillers are designed with energy recovery systems that capture waste heat and use it for other purposes, further increasing their efficiency and sustainability.
