High-Capacity Performance: New Rotary-Screw Compressors

Rotary-screw compressors are the backbone of modern industrial refrigeration, engineered for continuous duty and high-volume refrigerant flow. Stellar provides new replacement rotary-screw compressors from industry-leading brands including Frick, Vilter, Mycom, and GEA, utilizing both twin-screw and single-screw (gate rotor) architectures to meet the specific demands of your facility. Whether you are operating an ammonia-based cold storage facility or a process cooling loop using CO2 or synthetic refrigerants, our new screw compressor offerings deliver the volumetric efficiency and long-term reliability required for your most critical thermal loads.

National Sourcing for Critical Rotary-Screw Compressor Parts and High-Efficiency Consumables

Because rotary-screw compressors rely on oil injection for sealing, lubrication, and cooling, the integrity of your peripheral components is vital. Stellar provides national sourcing for genuine OEM parts and high-performance consumables for industry-leading brands such as Frick, Vilter, Mycom, and GEA. We stock and supply the high-wear items that keep your machines in service, including mechanical shaft seals, thrust bearings, and specialized gasket kits. Furthermore, we prioritize your system鈥檚 "clean side" by providing high-efficiency coalescing oil filters and application-specific lubricants, ensuring your oil management system effectively protects the precision-ground rotors from premature wear and thermal stress.

Precision Rebuilds: Restoring Your Screw Compressors to OEM Specifications

The tight clearances and complex geometries of a screw compressor require specialized expertise to restore once they begin to drift from factory specs. Stellar鈥檚 Compressor Services Team offers precision rotary-screw rebuilds, disassembling your units to perform exhaustive inspections of rotor profiles and housing tolerances. Our process includes expert rotor balancing and precision bearing alignment to eliminate vibration and ensure smooth, efficient operation. By restoring your screw compressors to original OEM specifications, we provide a cost-effective alternative to full unit replacement, extending the lifecycle of your capital assets and returning a high-performance, "like-new" to your critical refrigeration systems.
