Overview
About the Magnetic Bearing Oil-Free Chiller
Magnetic Levitation Compressor
A magnetic levitation compressor uses electromagnetism to suspend the compressor's rotating shaft in mid-air, completely removing physical contact between moving parts. Because there is no metal-to-metal friction, the system does not require lubricating oil. This eliminates the mechanical wear, energy losses, and complex oil management systems (pumps, separators, heaters) found in traditional centrifugal or screw compressors.
The BROAD Magnetic Bearing Oil-Free Chiller represents the pinnacle of electric cooling technology. By combining a frictionless magnetic levitation compressor with an integrated Variable Frequency Drive (VFD) and advanced falling-film evaporator technology, it delivers unparalleled energy efficiency, especially under part-load conditions where commercial buildings operate most of the time.
Eliminating lubricating oil from the refrigeration cycle has a profound impact on long-term performance. In conventional chillers, oil inevitably migrates into the heat exchangers, coating the tubes and insulating them - a phenomenon known as "oil fouling." This causes efficiency to degrade year after year. Our 100% oil-free design ensures the chiller maintains its exceptional "day-one" performance for its entire operational life.

Key Features
100% Oil-Free Design
Zero oil means no oil fouling in heat exchangers, guaranteeing sustained high efficiency over the chiller's entire 25+ year lifespan.
Unmatched Part-Load Efficiency
Integrated VFD precisely matches compressor speed to cooling demand, achieving Integrated Part Load Value (IPLV) COPs up to 11.
Ultra-Quiet Operation
The absence of mechanical friction and oil pump noise results in remarkably quiet operation, typically below 73 dBA.
Surge Prevention
Advanced active magnetic bearing control continuously monitors the shaft position thousands of times per second, ensuring stable operation even at low loads.
2-Amp Starting Current
Soft-start technology draws only 2 amps during startup, completely eliminating the massive electrical spikes common with traditional chillers.

Core Benefits
Drastic Operating Cost Reduction
Lower energy consumption combined with zero oil-related maintenance slashes Total Cost of Ownership (TCO) by up to 40%.
Simplified Maintenance
No oil changes, no filter replacements, no oil analysis, and no mechanical bearings to rebuild. Maintenance is largely reduced to standard sensor and tube checks.
Reliability & Uptime
Fewer moving parts and the elimination of the complex oil management subsystem mean fewer points of potential failure.
