Product Description

Product Description

As a pioneer in the application of variable speed oil-free magnetic bearing compressors, Kingfit has led the way by designing and building the most efficient chillers for Aluminum profile anodizing process, Central controlled air conditioning, Mushroom farm central control system.
Magnetic bearing chiller cooling capacity range: 105ton to 1000ton;
High efficienct falling-film evaporator.
Accurate temperature control ±0.1ºC.
Main shafts of the compressors rotate at high speed 48000RPM without any mechanical contact.
Oil-free design to reduce costs. Oil-free operation eliminates complicated oil system, reducing operational and maintenance costs.
Redundancy design and efficient operation.
Multiple compressors are installed on a shared evaporator and condenser, providing redundancy to ensure efficient operation of the chiller.
Magnetic bearing chiller has high energy efficiency and short payback period. Compared to conventional chillers, KINGFIT Variable Speed High Efficiency Magnetic Bearing Chiller can save 42% or even more operational costs with a payback period of just 2-3 years.
Environmental friendly, clean and safe. Use environmental friendly refrigerant R134a with zero ODP.
Intelligent control and high efficiency management. Unique PLC features adaptive control logic enables real-time optimization of the system to maintain best efficiency. Control panel has functions of capacity control, status display, fault diagnosis and other automatic control feature to ensure high efficiency management.
