Our magnetic bearing centrifugal chillers integrate high-speed direct-drive motors with frictionless magnetic bearing technology, eliminating the need for couplings, gearboxes, and conventional mechanical bearings entirely. This integration yields a simplified design characterized by no mechanical contact, zero wear, and maximum transmission efficiency—addressing the core pain points of traditional chiller systems (e.g., mechanical friction-induced wear and complex drivetrain maintenance).

A standout advantage of these chillers lies in their exceptional energy performance: their IPLV exceeds 12.5, and they deliver a potential energy savings of 30% to 50% when compared to standard chiller systems. This energy efficiency is further enhanced by the chiller’s two-stage compressor design, which incorporates inter-stage injection technology. Relative to traditional screw compressors or single-stage centrifugal compressors, this design boosts aerodynamic efficiency by 5% to 10%. More importantly, it expands the operational range, ensuring stable performance even under fluctuating load conditions.

Advantages
    Consistently High Thermal Performance
  • By eliminating mechanical friction and consequently obviating the need for lubricating oil, the chiller units achieve smooth operation. Simultaneously, the adoption of advanced heat exchange tubes increases turbulence, which improves heat transfer—this design sustains optimal efficiency over the long term.
    Quiet Operation

    The unit generates no noise from mechanical friction and is equipped with air cushions to isolate vibration. The compressor noise is below 77 dB(A), which eliminates the need for shock pads, spring shock absorbers, or soundproof enclosures.

  • 60 dB(A) – normal conversation
  • 70 dB(A) – loud speech
  • 85 dB(A) – average passing vehicle
    Enhanced Protection
  • Unlike conventional screw chillers, which have a starting current of up to 200A to 600A, the magnetic bearing inverter centrifugal chiller adopts soft start technology, reducing its starting current to a mere 6A. This extremely low starting current results in minimal impact on the power grid, eliminating the need for special protection measures.
    Eco-Conscious Refrigerant
  • Runs on R134a (HFC), a refrigerant recognized worldwide for its environmental safety profile.

We are manufacturers. We have two production bases plus two component-processing plants. All design, production, and sales are handled in-house. We can customize non-standard chillers or develop tailored solutions according to client requirements, offering both OEM and ODM services.

For medium to large scale facilities, the cooling demand is greater, and the cooling equipment must operate continuously without interruptions. In such cases, screw chillers are often the best option. Depending on site conditions, you might consider a water-cooled screw chiller for higher energy efficiency where water supply is stable, or an air-cooled screw chiller for easier installation and lower water usage.

In sites where there’s limited space, scroll chillers are an excellent choice. Their compact design allows them to fit into smaller areas while still providing reliable cooling performance, making them ideal for small-scale or space-restricted installations.

Electronics manufacturing requires high heat exchange efficiency and stable, continuous operation to maintain consistent product quality. Flooded or falling-film screw chillers are suitable for these applications, as they deliver precise temperature control and efficient cooling performance even under demanding production conditions.

In regions where water supply is scarce or inconvenient to access, air-cooled chillers are the best option. They do not require an external cooling tower, making installation more flexible and maintenance simpler, while still providing reliable cooling performance.
