Centrifugal Compressors for Industrial Refrigeration

High-Capacity Performance: New Centrifugal Compressors

For facilities requiring massive refrigeration capacity and high-volume flow rates, centrifugal compressors are the definitive high-tonnage solution. Unlike positive displacement units, these dynamic machines utilize high-speed impellers to convert kinetic energy into potential pressure energy, making them ideal for large-scale process cooling and central utility plants. Stellar provides new replacement centrifugal compressors from industry-leading brands, including York (Johnson Controls), Carrier, and Trane. By utilizing precise capacity management via inlet guide vanes, these high-efficiency units deliver steady-state performance for your most demanding refrigeration systems while optimizing overall facility energy consumption.

National Sourcing for OEM Centrifugal Compressor Parts and Specialized Components

The high-speed operation of centrifugal compression demands mechanical components engineered to extreme tolerances. Stellar is your single-source partner for national sourcing of genuine OEM parts to support your high-capacity fleet. We manage the logistics for specialized internal components—including hydrodynamic bearings, labyrinth seals, and volute gaskets—as well as critical monitoring hardware like vibration probes and temperature sensors. Furthermore, we provide the specialized, high-velocity lubricants and filtration products necessary to protect your high-speed rotating assemblies from thermal stress and premature wear.

Precision Rebuilds: Restoring Your Centrifugal Compressors to OEM Specifications

When a high-tonnage machine begins to drift from its performance envelope, a precision rebuild is a cost-effective alternative to complete unit replacement. Stellar’s expert Compressor Services Team specializes in the restoration of centrifugal assets, disassembling units to perform exhaustive inspections of shaft integrity and impeller profiles. Our rebuild process focuses on returning every component—from the gear assembly to the labyrinth seals—to original factory tolerances. By executing a complete shaft and impeller restoration, we eliminate efficiency losses and mitigate the risk of mechanical surge, returning a "like-new" high-performance machine to your critical refrigeration systems.
