Magnetic Levitation Chiller

The magnetic levitation/aerodynamic levitation chiller (DCWV/DQWV series) can be widely applied in places requiring refrigeration, such as modern agriculture, profile industries, data centers, electronics and chemicals, pharmaceuticals, and central air conditioning systems. It is particularly suitable for conditions of year-round use, offering energy efficiency and environmental friendliness. Compared to conventional screw compressors, it can achieve energy savings of up to 50%.

Product details

Product Description:

Product Features:

Oil free And Efficient:

Aerospace pneumatic design full load operation is more efficient, magnetic bearing friction less part load more efficient IPLV up to 10.81*full series; of first-class energy efficiency.

Stable And Reliable:

Spontaneous electric control mode spare bearing double protection to meet a variety of harsh conditions of safe operation.

Wde Range of Application coverage:

Dongxing maglev inverter centrifuge series can be widely used in modern agriculture,profile industry,data center,electronic chemical industry,pharmaceutical,central air conditioning and other places that need refrigeration.Especially suitable for use throughout the year.

Cost Saving:

The whole life cycle of oil-free operation,to avoid the oil film caused by the efficiency of the attenuation,electricity saving;no need to replace the lubricating oil and after, owner maintenance costs.

Intelligent Control:

Dongxing maglev unit has an advanced control system,and the large screen control interface can realize intelligent diagnosis and services such as "unattended"diagnosis service through effective data acquisition and management.

Noise Environmental Protection:

The horizontally opposed compression noise reduction structure ensures that the operating noise is as lowas75dB(A); Faling film evaporation technology reduces refrigerant charging and is more environmentally friendly.

Noise measurement according to jB/T 4330 and AHRl575,unit cooling capacity 100%, 1maway from the unit 1.5mon the ground test data.
