Servo Press T46 is a premium-grade compressor lubricant specially formulated for use in rotary vane, centrifugal, and screw compressors handling ammonia. Manufactured from high-quality turbine base stocks and fortified with carefully selected antioxidants and rust inhibitors, this oil provides exceptional oxidation stability and ensures trouble-free operation in ammonia-based systems. It has been designed to deliver long drain intervals, minimal sludge formation, and excellent metal protection under demanding industrial conditions. The oil’s formulation ensures that it remains chemically stable when in contact with ammonia and does not turn red or degrade, a common issue in compressor systems. With its strong resistance to oxidation, Servo Press T46 minimizes varnish and deposit buildup, keeping the compressor system clean and efficient. It also exhibits excellent water-separation characteristics, which help prevent corrosion and ensure smooth functioning of bearings, couplings, and seals. Servo Press T46 provides superior lubrication performance by maintaining film strength under high pressure and temperature conditions, ensuring reduced wear and extended equipment life. Its anti-rust and anti-foam additives further enhance protection and operational stability in continuous-duty applications. This oil is recommended for turbine-driven centrifugal compressors and screw or vane compressors equipped with common circulation systems for bearings and seals handling ammonia. Its reliable performance and ammonia compatibility make it a preferred choice for industries such as refrigeration, petrochemicals, and gas processing. Meeting stringent industrial requirements, Servo Press T46 is approved by Bharat Heavy Electricals Ltd., Hyderabad, and Consolidated Pneumatic Tool Co. (I) Ltd., Mumbai, for consistent and safe performance. With a viscosity of 43–48 cSt at 40°C, a flash point of 204°C, and a pour point of -6°C, this lubricant ensures dependable operation across varying temperature ranges. In summary, Servo Press T46 is an advanced, oxidation-resistant compressor oil that delivers excellent reliability, cleaner operation, and long service life — making it the ideal lubricant for ammonia-handling compressors in demanding industrial applications.
