What is Direct Cooling Oil free Frequency Magnetic Bearing Chiller

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 the Aluminum profile anodizing lines.

Corrosion-resistant high efficient falling-film evaporator, directly cooling acid liquid.

Accurate temperature control +/-0.1℃.

The 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 systems, 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.

The magnetic bearing chiller has high energy efficiency and a 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 environmentally friendly refrigerant R134a with zero ODP.

Intelligent control and high-efficiency management. Unique PLC features adaptive control logic that enables real-time optimization of the system to maintain the best efficiency. The Control panel has functions of capacity control, status display, fault diagnosis, and other automatic control feature to ensure high-efficiency management.

1. High efficiency, at least 30% more energy-saving than screw chillers.

2. Starting current only 2A≈1 bulb to reduce the impact on the grid.

3. 30%~100% capacity auto control as a requirement.

4. Low noise.

5. Accurate temperature control to ±0.1℃.

6. Oil-free compressor, reduce operation and maintenance cost. (Avoid oil into the cooling system, which will reduce chiller efficiency 20%~30% after several years of operation).
