Oil-Free Centrifugal Chiller Eliminating Maintenance Costs
MagBoost Magnetic Levitation Centrifugal Chillers
Oil-Free Excellence with COP 6.774 and 20-Year Maintenance Savings of 100 Million+
Product Overview
The Midea MagBoost Magnetic Levitation Centrifugal Chiller series represents the pinnacle of water-cooled cooling technology, offering capacities from 230 to 3,000 RT on R134a refrigerant. This revolutionary series eliminates traditional oil lubrication through magnetic bearing technology derived from aerospace engineering, enabling true oil-free operation with significant implications for system efficiency and maintenance.
The back-to-back two-stage compression system incorporates aerospace-derived aerodynamic technology, achieving 4% improvement in full-load efficiency and 7% improvement in part-load efficiency. Permanent magnet synchronous motors deliver superior performance across the operating envelope, while microchannel evaporator technology reduces refrigerant charge and improves heat transfer by 25-30%.
Advanced protection systems include 20kHz high-frequency position monitoring with μm-level levitation precision, self-power generation mode for emergency operation, and redundant backup bearings. The chiller operates stably with cooling water temperatures as low as 12°C and supports single-compressor loads down to just 10%, providing exceptional flexibility for variable load applications.
With COP reaching 6.774 and IPLV reaching 12.03, the MagBoost series delivers extraordinary efficiency. The complete 5-year warranty combined with 10-year magnetic bearing compressor warranty provides unmatched confidence. Critically, the design supports seamless transition to next-generation refrigerants including R1234ze, R513A, and R515B, future-proofing installations against evolving environmental regulations.
