MagBoost Magnetic Levitation Chiller
R134a Oil-Free 230-3000RT Centrifugal System featuring revolutionary oil-free centrifugal technology for ultimate efficiency and reliability.
Product Overview
The Midea MagBoost Water Cooled Centrifugal Chiller series introduces revolutionary oil-free centrifugal technology, establishing new benchmarks for efficiency, reliability, and environmental responsibility. Featuring proprietary magnetic bearing technology, these chillers span capacities from 230 to 3000RT, redefining performance expectations for large-scale cooling applications.
The groundbreaking back-to-back two-stage compression architecture delivers 4% improvement in full-load efficiency and 7% improvement in part-load efficiency when compared against conventional magnetic bearing centrifugal chillers. The permanent magnet synchronous motor with direct drive technology eliminates gearbox losses, further enhancing overall system efficiency.
With micro-channel refrigerant-cooled variable frequency drives (VFD) developed through proprietary research and development, Midea has overcome traditional challenges related to heat dissipation, harmonic distortion, and IGBT reliability. The innovative backup bearing system incorporating self-power generation capability ensures safe landing probability 300 times greater than conventional systems during power interruption scenarios.
