For power utility aerial buckets, scissor lifts, towable air compressors and more, Bio-Ultimax 1500 Dielectric Hydraulic Fluids meets the needs where high dielectric (greater than 35 kV) insulating properties are desired. Available in ISO 22, 32, 46 and 68 weight formulas that meet or exceed ASTM D877 specifications, they perform well in low and high-pressure hydraulic systems that require Anti-Wear (AW), anti-rust, anti-oxidation, anti-foam, and de-emulsibility properties.

These readily biodegradable biosynthetic formulas have oxidation performance comparable to full synthetics, yet they are safe for employees and the environment, so they help companies achieve their sustainability goals. Bio-Ultimax super high viscosity index fluids are proven in systems up to 10,000 psi and in systems with ultra-fine filtration. Available in one- and five-gallon pails, drums, totes and in bulk, they are ideal for use in all types of hydraulic systems where dielectric properties are desired, including utility bucket trucks, scissor lifts, towable air compressors, hydraulic vane, and piston and gear-type pumps.

To ensure performance and long life, Renewable Lubricants developed the stringent IsoGreen filtration standard, which meets or exceeds the Rexroth pump guidelines for hydraulic fluids. Non-toxic, zinc-free formulations contain no heavy metals. A direct replacement for mineral oil-based hydraulic fluids, Bio-Ultimax is ideal for hydraulic systems where low toxicity, biodegradability and non-bioaccumulation properties are required.

With patented antioxidants, these bio-synthetics provide improved performance in oxidation stability over standard plant/vegetable-based hydraulic fluids and unsaturated ester-based (HEES-type) fluids. They are highly inhibited against moisture and rusting in both fresh and seawater, and pass A and B sequences of the ASTM D-665 Turbine Oil Rust Test.

Bio-Ultimax Hydraulic Fluids meet and exceed federal specifications for machine tool hydraulic systems, especially those of EDM machines, and can replace specification MIL-PRF-17672E for ground support equipment. It meets U.S. Environmental Protection Agency 21013 Vessel General Permit guidelines for environmentally acceptable lubricants.
