Magnetic Bearing Centrifugal Chiller

—— Product Description ——

The Withair® Magnetic Bearing Centrifugal Chiller is a revolutionary advancement that challenges everything about conventional chiller design.   Built upon decades of industry-leading chiller expertise, our engineers questioned every component, analyzed every function and challengedevery assumption. The Magnetic Bearing Centrifugal Chiller’s design is enhanced with the next-generation, low-GWP R-513A refrigerant. This refrigerant provides a 55% reduction in GWP over R-134a helping you meet sustainability goals by reducing the impact to the environment, delivering superior real-world performance, lower cost of ownership and a new definition of sustainability.

The magnetic bearing centrifugal chiller from Withair® is designed to help address these challenges, lowering installation expenses and making it ideal for both existing structures and new construction projects, and data center application.  With its innovative design and comprehensive range of benefits, the chiller is a forward-thinking solution for your thermal management needs.

—— The Key Advantages Include —— 

● Magnetic Bearing Driveline 

The Withair® Magnetic Bearing Chiller uses an integral, variable-speed driveand advanced magnetic bearing technology to deliver extraordinary efficiency, superior durability, simplified maintenance and a wider operating envelope than any chiller using oil- or refrigerant-lubricated compressor bearings.  This driveline features a single moving assembly suspended in a magnetic field that does not require lubrication, With 80% fewer moving parts than traditional oil- or refrigerant-lubricated drivelines, longevity is enhanced and maintenance is reduced.

● Adaptive Frequency Drive

Enhances chiller efficiency at reduced loads with the fully integrated variable-speed drive.  This advanced drive works with the chiller motor and Smart equipment controller to continuously match the compressor speed, providing quieter operation across the chiller’s operating map for acoustically sensitive environments.

● Falling Film Evaporator

The Withair® falling film desian of the Magnetic Bearing Chiller reduces refrigerant charge up to 60%,and reduces evaporator shell size up to 20%, compared to other floodedlow-pressure refrigerant designs.

● Energy-Efficient Operation

With full load and Integrated Part Load Values (IPLV) that outperform the ASHRAE® 90.1-2022 standard, the Agility chiller helps reduce electrical consumption and demand charges, contributing to lower operating expenses. At AHRI conditions, some units can unload down to 10% of design tonnage with constant entering water temperature, delivering efficient performance even at lower loads.

● Intellectualized Control, Simple Operation

* Unit adopts PLC control technology, "a key start" and automatic operation.

* In the man-machine interface screen English display, touch screen/LCD text interface for your option.

* Units with remote control functions: turbine control system with built-in WEB browser,users can pass on any computer through internet in the remote monitoring and control unit can operation conditions and parameters of the work unit, the query of the unit.

● Protection Function Origin

* Units provided the refrigeration system, electrical system and the water system of the complete protection function, ensure its safe operation.

* Unit Settings: unit of power of inverse phase), (high/low refrigeration system protection, oil is too low to high temperature, vent protection system to protect and water flow protection, antifreeze protection safety protection function, guarantee the safe and stable operation of the mechanism.

● Heat Recovery Function

Units can be based on user needs, increase the heat recovery function, at the same time in refrigeration heat side will recycle waste heat utilization,and use side and heat side, improved the two-way unit running condition, improve the efficiency of the unit, the unit greatly reduce the operation cost.

● Ideal for comfort and process cooling, glycol chilling, heat recovery and heat pump applications

● Compatible with open- or closed-circuit cooling towers, dry air coolers or adiabatic coolers
