TERESSTIC oils are the primary recommendation for applications that require clean, dependable lubrication for extended service periods – often for years. They effectively resist high temperatures, prevent rust, and shed entrained water and air. Because the quality of TERESSTIC oils is especially apparent at sustained high temperatures and other adverse operating conditions, they are the prime lubricant recommendation for mild duty industrial gas turbines that require mineral lubricating oils. In addition, TERESSTIC oils give outstanding performance in hydraulic systems, circulating lubrication systems, gear cases, bearings, and other industrial units, where an RandO lubricant is required, for which long trouble-free service is required. Their high flash points suit TERESSTIC oils for use as heat transfer fluids in open systems. TERESSTIC 32 and 46 – These grades are formulated for applications where a premium quality grade 32 or 46 lubricant is required, but where service conditions are not severe enough to require the super-premium qualities of TERESSTIC GT 32 and 46. TERESSTIC 32 and 46 are of the same high quality as the heavier TERESSTIC grades and provide excellent performance in mild duty applications. Contamination of TERESSTIC oils with other products such as detergent motor oils may substantially impair their quality and could lead to operational problems such as foaming, filter plugging and sludge formation.
