Renewable Lubricants Bio-Ultimax 1500 Dielectric Hydraulic Fluids

Renewable Lubricants presents patented Bio-Ultimax™ 1500 Dielectric Hydraulic Fluids for power utility aerial buckets, scissor lifts, towable air compressors, and other stationary or mobile utility equipment where high dielectric (>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 demulisibility 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 (VI) fluids are proven in systems up to 10,000 psi and in systems with ultra-fine filtration.

Available in 1- and 5-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, piston and gear-type pumps, and more

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. In addition to enhancing performance, Bio-Ultimax™ helps companies achieve their sustainability goals.

With a higher VI than synthetics (Energy Conserving Formulas), Bio-Ultimax™ 1500 has improved thermal shear stability and increased load capacity. Their extremely low volatility increases the flash and fire safety features, making them safer to use. 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 (Stabilized™*), these biosynthetics provide improved performance in oxidation stability over standard plant/vegetable/HETG and unsaturated HEES type fluids. They are highly inhibited against moisture and rusting in both fresh and sea water, and pass A and B sequences of the ASTM D-665 Turbine Oil Rust Test. Formulated to provide a longer seal life with reduced oil leakage, this environmentally friendly, zinc-free product meets or exceeds high-pressure pump requirements.

Very little wear was encountered in field studies and in accelerated pump tests using biobased formulations in Denison T-5D, Vickers 20VQ, 35VQ-25 (M-2950-S), and V-104C (ASTM D-2882), Vickers I-286-S pump stand tests and pressures and temperatures ranging from 2000 to 3000 psi and from 150°to 210°F. Anti-wear performance exceeds requirements for US Steel 126, 136, and 127, load stage 10 in the FZG (DIN 51524 part 2 and 3 - HLP/HVLP), Parker-Denison HF-O/T6H20C, HF-1, HF-2, Eaton-Vickers M2950-S (35VQ-25) and I-286-S (V-104C), Rexroth, Sauer-Sundstrand, and GM (LS-2).

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 (is this accurate?). It meets EPA 21013 Vessel General Permit (VGP) guidelines for Environmentally Acceptable Lubricants (EALs) and should be used in hydraulic systems where low toxicity, biodegradability, and non-bioaccumulation properties are required.

Renewable Lubricants, Inc. began as a research and development company in 1991, developing high performance products that would directly replace petroleum-based products. Starting from a single corn-based engine oil developed in the inventor’s garage, the company now offers more than 250 products and has over 100 worldwide patents. They manufacture their products as environmentally friendly as possible without sacrificing performance.
