ConocoPhillips Hydroclear Diamond Class® AW Turbine Oil 32
Categories: Fluid; Lubricant

Material Notes: Diamond Class AW Turbine Oil is a premium quality, rust and oxidation (R&O)-inhibited, antiwear turbine oil developed for use in geared and direct-drive gas turbines and steam turbines in severe service. Diamond Class AW Turbine Oil is formulated with premium hydrocracked base oils and select additives to provide outstanding oxidation resistance, excellent wear protection, protection against rust and corrosion, and resistance to foaming. It has outstanding oxidation resistance and thermal stability at high temperatures to minimize deposit formation and provide long service life. It protects system components against rust and corrosion. It has excellent water-separating properties to minimize the formation of emulsions and is resistant to excessive foam buildup that can interfere with proper lubrication. An ashless (non-zinc) antiwear additive provides wear protection for gears and bearings. Diamond Class AW Turbine Oil is filtered to an ISO Cleanliness Code of 18/16/13 for use in circulating systems with tight tolerances where particle contamination can cause operational problems. The bulk oil is filtered at the blending terminal prior to filling any package containers, and is filtered again upon delivery in bulk to the customer’s bulk tank.
