PETRONAS FRIGOR M 4

Refrigeration compressor oil with high stability and low pour points

PETRONAS Frigor M4 is a high-quality naphthenic compressor oil developed specifically for use in refrigeration systems running on HCFC and CFC refrigerants (such as R22, R502, R12), ammonia (R717) and hydrocarbons such as R600a and R290. Thanks to its refined naphthenic base oil, Frigor M4 delivers excellent performance in both commercial and industrial refrigeration.

This oil stands out for its low pour point and very low wax content, preventing malfunctions at low temperatures. At the same time, the oil remains stable at high temperatures, preventing deposits and sludge formation. This extends the service life of both the oil and the refrigeration system.

Thanks to its proven technology, Frigor M4 is widely applicable in open, semi-hermetic and hermetic compressors and is used worldwide by leading compressor manufacturers.
