York 011-00549-000 Oil

The York 011-00549-000 is an OEM-grade 5 Gallon POE Type H Oil specifically engineered for high-performance lubrication in York centrifugal chillers and single-stage compressors. This Polyol Ester (POE) lubricant is formulated for systems utilizing R-134a, R-513A, and R-1234ze refrigerants, providing the critical miscibility required for effective oil return in large-scale HVACR applications. As a Type H oil, it features a higher ISO viscosity compared to standard Type K oils, making it the technician's choice for chiller commissioning and systems operating under extreme ambient conditions exceeding 104°F. Its advanced synthetic lubricant base includes anti-wear additives and oxidation inhibitors to prevent the formation of sludge and varnish within the refrigeration cycle. Maintaining the specific lubricant viscosity for York YK, CYK, and YD chillers is essential for protecting internal bearings and ensuring thermal stability during long-term operation. Utilizing this certified HVAC oil prevents compressor burnout and maintains peak heat transfer efficiency.

• High Viscosity Stability: Engineered as a Type H POE oil to provide superior film strength in high-temperature HVAC environments.
• Refrigerant Compatibility: Fully miscible with HFC and HFO refrigerants including R-134a and R-513A to ensure reliable oil return.
• Advanced Additive Package: Contains specialized anti-corrosion and anti-wear agents designed to extend the service life of centrifugal compressor components.
• Hygroscopic Protection: Packaged in a 5-gallon container to maintain chemical stability and resist moisture absorption during chiller maintenance.

When should I use Type H Oil instead of Type K?
Technicians typically utilize York Type H oil for the commissioning phase or in plant rooms where ambient temperatures consistently peak above 104°F (40°C) to ensure adequate compressor lubrication.

Is York 011-00549-000 backwards compatible with mineral oil?
This Polyol Ester lubricant is compatible with residual mineral oil during refrigerant retrofits; however, strict moisture control and acid testing are required to prevent hydrolysis during the transition.

What refrigerants are approved for use with this Type H Oil?
This synthetic refrigeration oil is specifically certified for use with R-134a, R-513A, and certain A2L refrigerants like R-1234ze in York brand equipment.
