York 011-00949-000 Oil

The York 011-00949-000 oil is a high-performance Type V alkylbenzene refrigeration oil designed specifically for large-tonnage centrifugal and reciprocating compressors. This 5-gallon lubricant is engineered to provide superior thermal stability and chemical resistance, making it the preferred choice for industrial chillers operating with HCFC refrigerants like R-22. As an alkylbenzene lubricant, it features an exceptionally low floc point, which prevents wax separation at low temperatures and ensures efficient heat transfer across evaporator bundles. Unlike standard mineral oils, this centrifugal compressor oil maintains a high viscosity index, ensuring a consistent lubricating film on critical bearing surfaces even under high-load conditions. For technicians servicing York YK or YT chiller systems, utilizing the 011-00949-000 York oil is essential for optimizing oil return and preventing carbon buildup on discharge valves. This industrial-grade HVAC lubricant is formulated to minimize foaming, which protects the oil pump and maintains steady oil pressure throughout the refrigeration cycle.

Key Benefits

• Enhanced solubility with HCFC refrigerants ensures reliable oil return and prevents sump depletion.
• Exceptional oxidative stability increases the service life of the lubricant and reduces sludge formation.
• Compatible with older York systems requiring Type V specifications for heavy-duty cooling applications.
• Optimized for low-temperature fluidity, protecting system components during cold starts.

Common Question

Is York 011-00949-000 oil compatible with HFC refrigerants like R-134a?

No, this Type V alkylbenzene oil is specifically intended for HCFC and CFC systems. For HFC-based units, a POE (Polyolester) oil is required to ensure proper miscibility. Always verify the compressor nameplate and York technical manual before changing oil types to prevent mechanical failure.
