Air Bearing Centrifugal Chiller

—— Product Description ——

Withair’s GC series normal temperature water-cooled variable frequency dynamic air bearing centrifugal chiller is a new generation of chiller designed and developed by our company.

Withair® GC series of centrifugal chillers uses dynamic pressure air bearing centrifugal compressors, which have the advantages of high efficiency, energy conservation, and environmental protection.

The unit is equipped with an oil-free system, which eliminates the need to replace lubricating oil and achieves almost zero maintenance operation, greatly reducing operating costs.

According to user needs, this series of products can provide refrigerating medium with temperature range of 4 to 16˚C, Water Cooled models from 80 to 1,458 Tons, a wide coverage range and meet the cooling capacity demand of 5,000 to 50,000 square meters of building.

The air bearing centrifugal chiller is a kind of water chiller designed by centrifugal compressor with air bearing for rotating support. In the process compressor rotation, the bearing relies on the buoyancy of the air to support, without metal friction, and the whole unit is energy-saving efficient and quiet during operation. Energy-saving and quiet no less than conventional magnetic suspension units, and no complex magnetic bearing system.

The heat exchanger design adopts a new type of heat exchange tubes and combines the system's heat exchange design and fluid simulation technology, thereby maximizing the heat exchange capacity.

Withair® GC series of centrifugal chillers offer a compact, efficient, and sustainable thermal management solution. Ideal for new construction and existing buildings, they help lower installation costs while modernizing system performance and versatility. Also serve as a cold source for various industries such as central air conditioning, data center, pharmaceuticals, chemicals, electronics and food.

Withair’s design incorporates system advantages such as:

• Best part-load efficiency: 0.31kW/ton, best full-load efficiency: 0.52kW/ton (at AHRI conditions)

• Achieve high performance with low sound while minimizing maintenance costs.

• Industry-renowned reliability, More flexibility with system enhancement options.

• Available with R-134a or next-generation low-GWP R-513A refrigerant.

• Water Cooled models from 80 to 1,548 tons, Available with dual circuits.

• Leveraging oil-free dynamic pressure air bearing with enhanced compressor speeds delivers amazing energy efficiency.
