Conoco Hydroclear Ultra-Clean Multipurpose R&O Oil is a premium quality, ashless, rust and oxidation (R&O)-inhibited mineral oil developed for the lubrication of industrial equipment requiring an ultra-clean, general-purpose circulating oil. It combines the same high-performance characteristics as our regular Multipurpose R&O Oil with the added advantage of fine filtration to a typical ISO Cleanliness Code of 17/15/11, for use in circulating systems with tight tolerances where particle contamination can cause operational problems.
Hydroclear Ultra-Clean Multipurpose R&O Oil is available in four viscosity grades: ISO 32, 46, 68 and 100. It is formulated with high-quality, hydrocracked base oils and an ashless, zinc-free antiwear additive package. It has excellent oxidation resistance and thermal stability at high temperatures to minimize sludge and varnish formation, and provide long service life. It protects system components against rust, corrosion and wear. 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.
Hydroclear Ultra-Clean Multipurpose R&O Oil, ISO VG 46, is approved by Alstom under their HTGD 90117 specification for bearing lubrication in their geared turbines.
