● Lower start-up costs with maintained high cooling capacity and efficiency
Dual-Loop Energy Optimization
● Real-time adjustment of VFD speed and IGV angle
● Maintains optimal efficiency under all load conditions
● Stable operation of Air-Bearing Centrifugal Chiller down to 10% load
● Prevents surge or bypass risks under fluctuating demands
Refrigeration Circuit & Control
100% Oil-Free Refrigeration Circuit
● Entire refrigeration circuit contains zero oil
● Eliminates efficiency loss caused by oil films on heat exchangers
● No routine oil maintenance required
● Lowers operating costs and environmental impact
High-Efficiency Heat Exchangers
● Reinforced copper tubes with titanium inserts for corrosion resistance
● Microfinned surfaces improve nucleate boiling and condensation efficiency
● Removable tube bundle allows in-situ cleaning without refrigerant recovery
Intelligent PLC Control
● LynxMind™ PLC records operational parameters every second
● Stores 12 months of trend data
● Predictive diagnostics for air-gap, impeller, and heat exchanger scaling
● Integration with BMS/DCIM; optional cloud connectivity for remote monitoring
Near-Silent, Low-Vibration Operation
● Air-bearing and VFD control eliminate friction and power pulsation
● Full-load sound pressure ≤80 dB(A) at 1 m
● Vibration transmission to building structures nearly zero
● No need for spring-mounted vibration isolation of Air-Bearing Centrifugal Chiller
