transformer oil, originating from the base fluid used in the oil has been a matter of serious concern. There have been numerous documented cases of failure traced to presence of corrosive sulphur, leading to elaborate investigations all over the industry. Naphthenic base oils, traditionally regarded as the best base fluids for transformer oils cannot be made totally devoid of sulphur, even by the best available techniques. Some manufacturers use passivators as additives in transformer oils to reduce the effect of corrosive sulphur. This approach only marginally reduces the risk of corrosive sulphur effect. The key to transformer oil performance therefore is directly linked to use of better base oil with zero sulphur made from advanced refining technology.

These oils are produced by blending of judiciously selected highly refined basestocks which have higher naphthenic ring carbon content, saturated ring, unlike unsaturated aromatic oils These oils are lighter coloured and non-staining, have excellent compatibility, excellent low temperature properties, good colour and thermal stabilities. Different grades available for various applications are summarized in the table below.

Metalworking, one of the most important industry segments, is known for its continuous improvement of the production process. The ever increasing demand for high quality products requires a constant and flexible automation of the metalworking processes and introduction of numerically controlled machines as well as new materials for tools and fluids for cooling. All these developments have led to faster machines, higher permissible cutting temperatures and faster cutting speeds. Metalworking industry uses huge quantity of cooling fluids and the health aspects of working with these fluids are as important as the need for tools and metal cutting fluids to have a long service life.
