RSC Bio Solutions announced that its EnviroLogic 3068 and EnviroLogic 3100 high performance hydraulic fluids have been approved for use in MAN Diesel & Turbo systems. This approval allows RSC Bio Solutions to serve customers who have MAN stern tubes and propellers, primarily in the marine transport, ferry and fishing industries.   The EnviroLogic 3000 Series consists of readily biodegradable synthetic hydraulic fluids designed for extreme operating temperatures and pressures. Because they are formulated to provide exceptional oxidation and thermal properties, these products are ideal for mobile or marine hydraulic and propulsion systems operating in environmentally sensitive areas, RSC Bio Solutions siad. The hydraulic fluids can withstand temperatures as high as 150°F or as low as -20°F, and they can handle pressure as great as 5,000+ psi.
