Midea MagBoost Oil-Free Magnetic Bearing Centrifugal Chiller
Investment Overview
The Midea MagBoost Water Cooled Centrifugal Chiller represents a generational leap in chiller economics. By eliminating oil from the compressor system entirely using active magnetic bearings instead of mechanical contact, this platform removes the single largest source of efficiency degradation, maintenance cost, and operational risk in conventional centrifugal chillers.
Performance metrics include COP of 6.774 at full load, IPLV of 12.03 at part load, and 70 dB(A) operating noise. Capacities span 230 to 3,000 RT on R134a with compatibility for R1234ze, R513A, and R515B low-GWP alternatives. The back-to-back two-stage impeller driven by a permanent-magnet synchronous motor delivers the highest volumetric efficiency in the centrifugal category, reducing annual cooling energy cost by 35-50% versus standard-efficiency centrifugal chillers.
Oil-free operation eliminates oil cooler loops, oil filters, oil analysis programs, and associated refrigerant-side fouling. Over a 25-year asset life, avoided oil-system maintenance saves $120,000-250,000 per chiller. Combined with the 5-year full-unit warranty and 10-year magnetic-bearing warranty, the MagBoost offers the most predictable lifecycle cost in the water-cooled centrifugal segment.
Total Cost of Ownership Advantages
- COP 6.774 / IPLV 12.03: Industry-leading efficiency delivers 35-50% annual energy-cost reduction with payback within 3-5 years
- Zero Oil, Zero Fouling: Eliminates oil-side maintenance and preserves heat-exchanger cleanliness throughout asset life
- Magnetic Bearing, 10-Year Warranty: No mechanical contact means no bearing wear, vibration, or lubrication system
- 5-Year Full-Unit Warranty: Most comprehensive coverage in the centrifugal chiller market
- 10% Minimum Load: Widest operating range in the class for efficient deep part-load operation
- 12°C Condenser Water Stability: Enables extended free-cooling hours in transitional seasons
- 70 dB(A) Operation: Quietest centrifugal chiller in its capacity range
- Multi-Refrigerant Compatibility: R134a baseline with low-GWP alternatives for regulatory compliance
- LEED Contribution: Supports LEED v4.1 Energy & Atmosphere and Materials & Resources credits
