The Maglev Centrifugal Chiller employs magnetic levitation compressor technology to deliver industry-leading COP values up to 6.3 with zero mechanical wear, zero oil, and near-silent operation. Ideal for large-scale HVAC, data center cooling, and district energy systems.
Maglev centrifugal chiller is a kind of new product developed by CIGU based on its key technology. It can be used in residential and industrial environments where there are huge demands for chilled water. Compared with traditional chillers, it features a higher energy efficiency ratio and can save energy by 30%-50%. At the same time, it is oil-free.
The maglev centrifugal chiller leverages frictionless magnetic bearing technology to drive the compressor without oil, achieving significantly higher energy efficiency, quieter operation, and a maintenance-free refrigerant cycle suitable for the most demanding cooling applications.
