Se rere. There are many problems MARINE REVIEW in turbine lubrication —but Dynol Turbine Oils solve them all IGH speeds, high tempera- tures, heavy pressures, water contamination, oil emul- sion—these are some of the prob- lems of turbine lubrication. Yet, under widely different operating conditions, each of these problems must be mastered by the oils you use in your tur- bines. At all times, these oils must form and hold a “film of protection” that safeguards each costly friction surface, even un- der the most exacting conditions. Dynol Turbine Oils In their years of experience with lubricants, the technologists of the Tide Water Engineering Bureau have developed a series of superior turbine lubricants— Dynol Turbine Oils. These oils have passed every test of bearing speed and gear tooth pressure. At alltimes they keep bearing temperatures at a minimum. They separate rapidly from water and are unaffected by radical temperature varia- tions. They may be filtered over and over again indefinitely. If you are not already using Dynol Turbine Oils, you ought to discuss them with one of our Staff Engineers. Have him call to tell you about the “film of protection” and the Tide Water Power Group. The F | —for ship machinery i ha their application to each phase of Power Plant lubrica- tion, the lubricants comprising the Tide Water Power Group form the “film of protection”, thin as tissue, smooth as silk, tough as steel. The application of the Tide Water Power Group to your machinery will give you truly economical lubrication— max- imum power, uninterrupted oper- ation and increased production. Tide Water Power Group GRENOL Pure Pennsylvania Cylinder Oils for all steam conditions, from wet steam to superheat. DYNOL Engine and Turbine Oils for engine bearings,turbines, gen- erators and air compressors. WAVOL Brands of engine oils for all bearing surfaces on reciproca- ting and Diesel engines.
