Air Suspension Variable Frequency Centrifugal Chiller

No oil circuit system
Zero friction operation

Ultra - high - precision dynamic pressure air - floating bearings
The unique multi - support fin - type dynamic pressure air - floating bearings can achieve a start - stop life of 300,000 times and a load - increase and decrease life of 1,000,000 times.

Oil - free design, reduced efficiency degradation
Traditional chiller units use lubricating oil, which forms an oil film on the surface of the heat exchanger and hinders heat transfer, resulting in an increase in the power consumption of the water chiller. The air - suspension unit operates without oil, and there is almost no efficiency degradation during the operation process.

Zero friction, low noise
Noise is an important factor in evaluating the impact of chiller units on the environment. Due to the use of air - suspension bearings, when the compressor is running, the moving parts are completely suspended, with zero friction. The operating noise can be as low as 72dB(A), which is much quieter than traditional screw units, with a noise reduction of 10 - 15dB(A).

Efficient heat transfer design of the condenser
The condenser heat exchange tube adopts a pin - fin design. The fin - shaped outer surface of the tube effectively disrupts the formation of the condensation liquid film, making the heat transfer more efficient and reducing heat resistance. With the dedicated air - distribution design for the oil - free system and by adjusting the distance and position of the condenser tubes, the condensation heat exchange effect is enhanced.

Dedicated air - distribution for the oil - free system of the evaporator
Flooded type (standard): The heat exchanger is fully immersed in the refrigerant, ensuring that the inner media of all heat exchange tubes are evenly evaporated. At the same time, with the dedicated air - distribution technology for the oil - free system and the optimized design of the liquid distributor structure, the layout of the tubes and their distance and position can be optimized to further improve the heat exchange efficiency. The falling - film evaporation mode can also be selected.

Intelligent control system
The control center is composed of a 10 - inch color liquid - crystal touch - display screen, which improves the convenience of identification, and the operation is simple and fast.
It centrally displays the simple process of the unit and various operation information. It centrally controls various settings and statuses of the unit.
Three - level access rights are set according to the different needs of factory settings, customer maintenance, and user use.
