MagBoost Maglev Chiller 230-3000 RT
Oil-Free IPLV 12.0 Zero Emission Operations: The Oil-Free Revolution Where Maximum Efficiency Meets Minimum Environmental Footprint
Product Overview
At the intersection of peak performance and minimum environmental impact, the Midea MagBoost Water Cooled Centrifugal Chiller represents the state of the art in sustainable cooling for the world's most demanding installations. Spanning 230 to 3,000 RT with COP 6.774 and IPLV 12.03, this oil-free magnetic bearing platform was designed for organizations that refuse to choose between operational excellence and environmental responsibility.
The elimination of oil from the compressor system is a sustainability transformation. Conventional oil-lubricated centrifugal chillers experience progressive efficiency degradation of 5-15% over their asset life as oil migrates into the refrigerant circuit. The MagBoost's active magnetic bearings levitate the shaft with zero contact, preserving the rated COP of 6.774 and IPLV of 12.03 year after year.
Key Features
Oil-Free Operation Preserving Rated Efficiency
The MagBoost's oil-free magnetic bearing system eliminates efficiency degradation entirely. The heat exchanger cleanliness factor remains at 0.995+ throughout the asset life, meaning the IPLV 12.03 achieved at commissioning is maintained for the life of the unit.
- Active magnetic bearings eliminate the entire oil lubrication system
- Heat exchanger cleanliness maintained at 0.995+ throughout asset life
- Rated COP 6.774 and IPLV 12.03 preserved year after year
- Eliminates 5-15% efficiency degradation of oil-lubricated centrifugals
- No oil cooler, oil filter, or oil-change schedule required
- 10-year magnetic-bearing warranty coverage
Multi-Refrigerant Strategy for Global Compliance
Designed for fragmented global refrigerant regulations with multiple low-GWP options to satisfy any regulatory environment worldwide.
- R134a baseline for global availability
- R1234ze (GWP less than 1) for stringent regulatory environments
- R515B (GWP 270) for ultra-low-GWP sustainability targets
- R513A (GWP 573) as near-drop-in R134a replacement
- All options factory-configured
Extended Operating Range and Free-Cooling Capability
10% minimum load operation with 12°C condenser water inlet stability creates the widest effective operating range in the centrifugal chiller category.
- 10% minimum load - widest stable operating range
- 12°C minimum condenser water inlet enables extended free-cooling
- 500-1,000 additional free-cooling hours annually
- Each free-cooling hour represents zero chiller energy consumption
- Full efficiency maintained at 10% load
Industry-Leading Efficiency Performance
COP 6.774 at full load and IPLV 12.03 at part load set the benchmark for water-cooled centrifugal chillers.
- COP 6.774 at full load - highest in category
- IPLV 12.03 at part load
- 35-50% annual energy-cost reduction versus standard centrifugals
- Back-to-back two-stage impellers boost efficiency
- Permanent-magnet synchronous motor for higher power factor
Ultra-Quiet Operation
At 70 dB(A) per AHRI 575, the MagBoost is the quietest centrifugal chiller in its capacity range, enabling indoor installation without acoustic enclosures.
- 70 dB(A) - quietest in capacity range
- Oil-free design eliminates gear-mesh noise and vibration
- Enables indoor installation within occupied structures
- Eliminates need for external plant structures
- Supports WELL and Fitwel acoustic-comfort requirements
Comprehensive Warranty and Lifecycle Support
The most comprehensive warranty in the centrifugal chiller market provides decade-long assurance of performance predictability.
- 5-year full-unit warranty covers all major components
- 10-year magnetic-bearing warranty
- Warranty provides decade-long performance assurance
- Reduced refrigerant charge supports LEED v4.1 credits
- Complete lifecycle transparency for ESG reporting
