TECHNOFLUID REFRIGERATION OIL (Grades 46 & 68)
Refrigeration Oil
TECHNOFLUID Refrigeration Oils 46 & 68 are premium-quality refrigeration compressor oils formulated from highly refined base oils with advanced additive technology.
Designed to provide excellent lubricity, chemical stability, and thermal performance under low-temperature operating conditions.
Exhibit high resistance to oxidation, ensuring long oil life and reliable compressor performance.
Offer excellent miscibility and compatibility with commonly used refrigerants.
Maintain fluidity at low temperatures, ensuring smooth compressor operation and reduced wear.
Key Benefits
Excellent lubricating film strength for effective wear protection of compressor components.
High chemical and thermal stability minimizes sludge, carbon, and deposit formation.
Low pour point ensures reliable lubrication during low-temperature start-up.
Superior oxidation resistance extends oil drain intervals and reduces maintenance.
Helps maintain system efficiency by keeping heat transfer surfaces clean.
Provides reliable sealing and lubrication of moving parts under continuous operation.
Applications
Recommended for refrigeration and air-conditioning compressors.
Suitable for use in:
Cold storage plants
Ice plants and chillers
Commercial refrigeration systems
