Engineered Refrigeration Lubricants for Efficiency, Longevity and Thermal Stability

In an industrial compressor, oil is a functional component, not just a lubricant. Whether your system requires mineral, alkylbenzene, or polyalphaolefin (PAO) formulations, the oil must maintain chemical stability under harsh refrigeration environments without breaking down into sludge or varnish. We provide lubricants specifically designed to seal the microscopic gaps between compressor rotors—ensuring maximum volumetric efficiency—while remaining fluid enough at low temperatures to return from the evaporator. By utilizing the ideal viscosity and formulation, we help you prevent "oil logging," protecting your heat transfer surfaces and extending the service life of your equipment.

OEM-Specified Fluids and the Stellar 717 Ammonia Blend 

Stellar is your resource for the specialized lubricants required by the industry’s leading compressor manufacturers. We provide exact-match fluids for Frick, Vilter, Mycom, and GEA systems, ensuring your equipment operates at peak efficiency while protecting your compressors for the long haul. For ammonia applications, we offer the Stellar 717 blend, our high-performance lubricant specifically formulated to resist foaming and thermal degradation common in high-cycle R-717 environments. By matching the precise miscibility and pour point requirements of your compressors, we eliminate the risks associated with generic aftermarket alternatives.

Predictive Maintenance Through Oil Analysis

Lubrication is the cornerstone of predictive maintenance. Because oil degradation is often the leading compressor health indicator, we provide comprehensive oil analysis services that serve as a diagnostic check for your compressors. We test for acidity, moisture content, and wear metals to identify potential bearing wear or seal failures long before they result in unscheduled downtime. Stellar’s analysis reports provide the data-driven insights needed to optimize your oil-change intervals and maintain the long-term mechanical integrity of your compressors.
