Hydraulic Circulating Oils
Hill and Griffith's PREMIER R&O Hydraulic Circulating Oils were specifically designed for all but the most severe high pressure applications, where high oxidation resistance and a maximum amount of water separation is necessitated.
The PREMIER R&O series is formulated with the highest quality base stocks and incorporates both rust and oxidation inhibitors as well as a metal passivator and defoamant additive. These products are ideally suited in circulating systems such as steam turbines and air compressors where maximum demulsibility of water from the oil is required. They do not contain anti-wear additives based on their application.
