Refrigerant Compressor Oils

Refrigeration compressors may use mineral, synthetic, alkylbenzene, polyol ester (POE), or polyalkylene glycol (PAG) oils. Selection is based on the compressor design, refrigerant, viscosity grade, and OEM specification. Products in this range support HFC, CFC, HCFC, ammonia, carbon dioxide, and natural-refrigerant applications, so compatibility should be confirmed before installation.

Confirm the compressor manufacturer’s oil specification, required viscosity, refrigerant compatibility, and existing lubricant chemistry. The range includes ISO grades such as 32, 46, 68, 100, 150, and other listed grades. US Compressor can provide technical guidance and free oil analysis to help evaluate lubricant condition and identify a suitable replacement.

Many products are described as 100% OEM compatible or as meeting or exceeding OEM specifications. Compatibility is product-specific and depends on the original lubricant, compressor, and refrigerant system. Review the individual product information and technical documentation before changing oil or topping up an operating system.

The product range includes POE lubricants designed for HFC and blended refrigerants, including products equivalent to Emkarate, Fuchs, BVA, Total, Cognis, Summit, and other listed brands. Available viscosity grades include options such as ISO 32, 46, and 68, along with other grades. Confirm the required grade and compressor specification before use.

Ammonia systems in the range include lubricants such as RCO 68, RENISO KC 68, RHT 68, R 717, and REFLO 68. These products are described for ammonia or R717 refrigeration compressors and may offer low solubility, low volatility, wear protection, and thermal or oxidative stability. Verify the compressor manufacturer’s specification before selection.

Yes. RENISO C 55 E Fuchs Refrigeration Oil Replacement by Talon and RENISO C 85 E Fuchs Refrigeration Oil Equivalent by Talon are listed for carbon dioxide refrigeration systems. Their product information describes optimised miscibility with CO2 refrigerants and use in industrial and commercial refrigeration equipment. Confirm the required viscosity and system specification before ordering.
