Sentinel’s SCO-REF Oil Series are a family of fully synthetic industrial lubricants developed specifically for refrigeration compressors. They are especially formulated synthesized hydrocarbon lubricants for severe service under conditions that are beyond the capabilities of conventional mineral oils. In addition, they improve the performance and efficiency of standard refrigeration systems compared to conventional mineral oils.

Sentinel SCO-REF have very low pour points, zero wax content, a high natural viscosity index and high thermal stability. They exhibit greater chemical stability in the presence of refrigerants and other system components, and have a low volatility. Their low solubility makes them suitable for systems using refrigerants such as R12, R22, R114 and ammonia.
