Product Description
High-Efficiency Air-Bearing Centrifugal Chiller for Commercial & Industrial Cooling (75RT-1000RT)
Our air-bearing chiller represents a leap forward in cooling technology, designed to meet high-demand cooling needs in commercial and industrial sectors. By adopting advanced air-bearing technology, it eliminates friction from traditional mechanical bearings, achieving an impressive energy efficiency ratio (EER) of up to 6.5. This significantly reduces energy consumption, operating costs, and carbon emissions.
Key Features and Benefits
  • ltra-High Efficiency: Air Suspension & Oil-Free Technology

    The Future of Frictionless Thermal Management and Sustainable Cooling

    1. Revolutionary Air Suspension Bearing Technology

    • Frictionless Aerodynamic Levitation: Our units utilize advanced Air Suspension Bearings, which create a high-pressure air film between the bearing and the rotor during operation. By eliminating physical contact, the system operates with zero mechanical friction.

    • Extended Service Life: Because there are no wearing parts within the bearing assembly, the mechanical longevity of the compressor is exponentially increased, ensuring stable performance for decades.

    2. Intelligent Variable Frequency Drive (VFD)

    • Dynamic Load Adaptation: Integrated with an Intelligent Frequency Conversion system, the compressor speed modulates in real-time to match the actual cooling demand.

    • Optimized Part-Load Efficiency: This eliminates the energy spikes associated with "on/off" cycling, ensuring the unit operates at its most efficient point regardless of whether the facility is at 10% or 100% capacity.

    3. Industry-Leading Energy & Cost Savings

    • 30%–40% Efficiency Gains: By combining frictionless bearings with VFD technology, these units achieve an energy efficiency rating 30%–40% higher than traditional screw or reciprocating units.

    • Rapid ROI: For high-utilization facilities (such as data centers or 24/7 manufacturing), the reduction in operational electricity costs often allows the equipment to pay for itself within a few years.

    4. Precision & Silent Performance

    • Surgical Temperature Accuracy: Engineered for mission-critical applications, the system maintains a precision of ±0.1°C. This level of stability is essential for semiconductor fabrication, laboratory research, and high-end medical imaging.

    • Ultra-Low Acoustic Footprint: Operating below 70 decibels, our units are among the quietest in the industry. This makes them ideal for noise-sensitive environments, including hospitals, office complexes, and urban data centers.

    5. Minimalist Maintenance & Sustainability

    • 100% Oil-Free Operation: The air suspension design completely eliminates the need for a lubricating oil system. You no longer need to manage oil pumps, oil filters, or oil separators.

    • Simplified Service Protocol: Maintenance is reduced to a single, simple task: annual air filter replacement. This drastically reduces labor costs and eliminates the risk of oil-contaminated heat exchangers.

    • Environmental Stewardship: Utilizing R134A refrigerant, the system meets strict international environmental standards, offering a high-performance solution with zero ozone depletion potential.
