Shell Refrigeration Oil S4 FR-V 68
Shell Refrigeration Oil S4 FR-V 68 is a high-performance synthetic refrigeration compressor lubricant formulated using alkylated benzene base fluids. The lubricant is designed to provide reliable lubrication and system cleanliness in refrigeration compressors operating with many commonly used refrigerants. Its formulation offers excellent solvency, strong oxidation stability and long service life, making it suitable for a wide range of refrigeration systems used in commercial, industrial and domestic cooling applications.
One of the key advantages of Shell Refrigeration Oil S4 FR-V 68 is its ability to support refrigeration system efficiency. The alkylated benzene base oil provides high solvency, helping maintain system cleanliness by preventing sludge and deposit accumulation within refrigeration circuits. Clean internal components allow refrigeration systems to maintain efficient heat transfer and consistent cooling performance. By helping prevent contamination and deposits, the lubricant contributes to reliable and efficient system operation over extended service intervals.
Shell Refrigeration Oil S4 FR-V 68 also offers excellent thermal and oxidation stability. Refrigeration compressors often operate at high discharge temperatures which can accelerate lubricant degradation. The formulation resists oxidation and maintains stable viscosity characteristics under demanding operating conditions. This helps extend oil drain intervals compared with conventional mineral refrigeration oils while maintaining consistent lubrication performance throughout the service life of the lubricant.
The lubricant also provides reliable wear protection for critical compressor components such as bearings, pistons and other moving parts. By forming a durable lubricating film between metal surfaces, the oil helps reduce friction and minimise mechanical wear during operation. This protection helps extend compressor life and maintain reliable operation in refrigeration systems that run continuously in commercial and industrial environments.
Shell Refrigeration Oil S4 FR-V 68 is recommended for use in open, semi-hermetic and hermetic refrigeration compressors used in domestic, commercial and industrial refrigeration installations. It is suitable for both rotary and reciprocating compressor designs. The lubricant is compatible with a wide range of refrigerants including ammonia (R717), carbon dioxide (R744), hydrocarbons such as propane (R290) and traditional CFC and HCFC refrigerants including R12 and R22. However, it is not recommended for use with HFC refrigerants.
Physical characteristics include a kinematic viscosity of approximately 68 mm²/s at 40°C and 6.2 mm²/s at 100°C with a density of approximately 871 kg/m³ at 15°C. The oil has a flash point of approximately 190°C and a pour point of approximately –39°C, supporting reliable lubrication performance across a wide range of refrigeration system operating conditions.
