High-Efficiency Oil-Free Magnetic Bearing Chiller For Industrial & Commercial HVAC

Falling-Film Evaporator Technology
Full Falling-Film Design:The fullfaing.-lm evaporator efectively prevents liquid carryover during high-speed operation of magnetic levitation centriflugal compressors, a commonissue in flooded systems. This aows the compressor to reach its maximum rotational speed and enables the chiler to delver higher cooing capacity.Compared to traditional looded evaporators, it eliminates the significant energy losses caused by staic liuid column pressure, improving heat exchangeefficiency by approximately 15% and greatly enhancing overall system reliability.Reduces refrigerant charge by up to 40%
Enhances energy efficiency and operational stability

Reliable Quality
The compressor adopts an oil-free magnetic levitation structure, eliminating mechanical wear and the need for lubricationsystems.All core components are sourced from internationally renowned suppliers.Each unit undergoes rigorous factory testing before delivery to ensure long-term reliability.
High Efficiency & Energy Saving
Equipped with a new-generation magnetic levitation variable-speed centrifugal compressor, the system operates
without oil, preventing efficiency degradation over time.
The lntegrated Part Load Value (lPiV) reaches above 9.0, delivering over 45% energy savings compared to
conventionalsystemsA high-precision liquid level sensor paired with an electronic expansion valve ensures accurate refrigerant flowrequlation based on system load.Specially designed oil-free flooded-type evaporators and condensers use enhanced heat transfer tubes, maximizingheat exchange efficiency and reducing power consumption
Low Noise, Low Vibration, Compact Design
The unit operates with extremely ow noise and minimal vibration, enabling flexible placement options.lts compact size saves mechanical room space, while the lightweight construction simplifies transportation andinstallation.The unit's modular width allows it to easily pass through standard industrial doorways, facilitating on-site installationand minimizing the workload of HVAC system retrofits.
Powerful Smart Control System
Features a PAC (Programmable Automation Controller) system known for fast computing, ease of usestrong interference resistance, and lightweight architecture.The controller ensures stable compressor operation while offering additional opportunities for energysavings.Over 50 safety protections are built-in, including dual safeguards for critical parameters (alarm andemergency shutdown).Supports remote monitoring, proactive alerts, email reporting, and online operation via Ethernet and othercommunication interfaces.
Permanent Magnet Synchronous Motor (PMSM) Technology
The hiah-speed PMSM delivers a motor efficiency up to 99% within the full operational rangeCompact and lightweight, the motor features a dense efficiency profile and tight construction.Refrigerant-cooled design keeps the motor's temperature field evenly distributed and controlled around 40°C, ensuring stable and efficient operation.Built with low-loss silicon steel cores and high-quality rare-earth permanent magnets, the motor is highly efficient andfeatures low total power loss.Uses Space Vector Pulse Width Modulation (SVPWM) technology for precise speed control, adapting in real-time toload changes with low starting and operating currents.This results in lower lifetime operating costs and reduced distribution infrastructure requirements
