Shell Refrigeration S2 FR - A 68 - 209 LT

BENEFIT Refrigeration Oil S2 FR-A 68 (209L): Refrigeration Oil S2 FR-A 68 is a low-miscibility, paraffinic mineral-based compressor lubricant. It is specifically engineered for cooling systems utilizing ammonia (R717) or hydrocarbon refrigerants. It provides high thermal stability and system cleanliness. Key Specifications & Performance Features: Base Fluid: Specially refined paraffinic mineral oil. Viscosity Grade: ISO VG 68. Container Size: 209 Liters (Large Industrial Drum). Evaporator Temperature Limits: Performs efficiently down to -30°C. System Efficiency: Formulated to limit oil carryover. This prevents heavy oil coating on evaporator surfaces to maintain consistent heat transfer. Extended Oil Drain: High resistance to oxidation and thermal breakdown minimizes sludge formation, even under high compressor discharge temperatures. Primary Applications: Ammonia Systems: Optimized specifically for industrial refrigeration systems running on Ammonia (R717). Hydrocarbon Systems: Suitable for refrigeration equipment using hydrocarbons such as Propane (R290). Compressor Types: Fully compatible with open, semi-open, and hermetic compressor configurations, including both rotary and reciprocating designs. Crucial Recommendations & Restrictions: Refrigerant Incompatibility: Do not use this lubricant with CFC, HCFC, or HFC refrigerants like R12, R22, or R134a. Oil Separation: Best utilized in chilling systems equipped with dedicated oil separation mechanics, maximizing oil recovery before the fluid reaches the evaporators. Seal and Oil Compatibility: Fully miscible with conventional mineral oils, PAO, and alkylated benzene lubricants. It functions safely with standard sealing materials built for mineral oils.
