Industrial Lubricating Oils

 Circulating Oils are a blend of solvent refined base oils, and select anti-oxidant, anti-rust and anti-foam additives. They meet the requirements of very high pressure systems as also of systems operating with high pump speeds. These oils match the requirements of ISO:VG 220 to 460 as well as IS:10522-1983 (Reaffirmed 1993); IS:3098 – 1983 (Reaffirmed 1993); and DIN – 51524 for Hydraulic Oils H and H-L. Higher viscosity grades (Grades 220 to 460) are not covered in Indian Standards (IS) but are fortified with some amount of anti-wear properties to ensure optimum protection and conform to IPSS 1-09-022 and USS 127. The oils also pass Vickers Vane Pump Test

Quenching Oils are a series of heat treatment fluids, each with a different viscosity, for various metal quenching objectives. The series includes  Quenching Oil 39I, 39L, 39LI, 42L, 43L and 45HL. Of these, 39I and 39L are formulated using Group II base oil and are general purpose quenching oils. 39L is of low viscosity. 39LI has higher flash point and low volatility. 42L is a compounded type quenching oil with low viscosity. 43L and 45HL are additive type quenching oils with low viscosity range. Standards:  Quenching Oils are blended using solvent refined base oil with specially selected additives and conform to performance specifications as per BIS:2664-1980 (reaffirmed 2014) compounded type. Advantages:  Quenching Oils enable accelerated quenching through proper and controlled cooling and impart uniform hardness to quenched components. These oils possess excellent thermal and oxidation stability. They also have high flash and fire properties. Minimal losses due to evaporation, hence reduced top-ups and low volatility hence reduce consumption, making them cost effective. They also reduce sludge formation and minimize oil thickening making the oils effective for longer periods.
