PETRONAS FRIGOR M 4

Refrigerant compressor oil with high stability and low pour points

PETRONAS Frigor M4 is a high-performance naphthenic compressor oil, specially developed for use in refrigeration systems with 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 offers excellent performance in both commercial and industrial refrigeration.

This oil features a 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 life of both the oil and the cooling 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.
