Air-Suspending Variable Frequency Centrifugal Chiller

Air-Suspending Variable Frequency Centrifugal Chiller

The Air-Suspending Variable Frequency Centrifugal Chiller independently developed by SINO KING is a device that provides cold sources for air conditioning systems. This unit adopts an efficient, stable, reliable, and low-noise air-suspending variable frequency centrifugal compressor, ultra-high-precision air-suspending bearing technology, and a high-speed permanent magnet variable frequency motor, achieving zero-friction bearing operation and ultra-low power consumption. The system requires no lubricating oil, has no external oil circuit design, features few vulnerable parts, and incurs low operation and maintenance costs.
Product Features
  • Air-Suspending Variable Frequency Centrifugal Compressor

      Air-Suspending Variable Frequency Centrifugal Compressor

      The rotor is completely suspended, requiring no lubricating oil and achieving zero mechanical friction; automotive-grade air-suspending design ensures an ultra-long service life; permanent magnet variable frequency direct-drive motor reduces mechanical loss and improves efficiency; quiet operation with noise levels below 75dB.
  • Flooded/falling film evaporator

      Flooded/falling film evaporator

      The standard flooded evaporator, with an oil-free system, maximizes the heat exchange performance; supports customization of falling film evaporators for efficient heat transfer with minimal refrigerant charge
  • Two-Stage Subcooling Technology

      Two-Stage Subcooling Technology

      Economizer secondary deep subcooling reduces refrigerant flash loss and increases the unit's cooling capacity; intermediate-temperature gas injection mixes with first-stage compression discharge gas to lower exhaust temperature.
  • Auto-cleaning device

      Auto-cleaning device

      A condenser auto-cleaning device can be configured, which features an integrated end-cover design for online cleaning without disassembly, extending the maintenance intervals of the unit
