Bio-HVO™ Hydraulic Fluid
Bio-HVO™ Hydraulic Fluids are ultimately biodegradable vegetable based formulas that have been USDA Biobased tested to show new carbon (vegetable oil) at >96% and they are Specially formulated to offer the lowest toxicity in aquatic conditions. They are an excellent choice for inner plant applications (ie. Steel Mills) as fire resistant (FR) hydraulic fluids, with exceptional oxidation stability (RBOT 350-400 minutes) and exceeding US Steel minimum requirement of 120 minutes. Although they have a pour point of -25°C, care must be taken if used in hydraulic systems setting static below 0°C for extended periods.
Bio-HVO™ Hydraulic Fluids are formulated to perform in stationary and mobile hydraulic systems that require Anti-Wear, Anti-Rust and Anti-Oxidation properties. These patented super high VI fluids have a long history of successfully being used in hydraulic systems designed with vane, piston, and gear-type pumps, that require DIN 51524 Part 2 and 3, Parker-Denison HF-O, HF-1, HF-2, Eaton-Vickers, Rexroth, and Sauer-Sundstrand. They also meet the requirements for ashless GL-1, GL-2, GL-3 and AGMA Non-EP gear oils in reduction units and gear sets where they meet the viscosity ranges. Their anti-wear performance exceeds the requirements for GM (LS-2), US Steel 126, 136 and 127, and DIN 51524 Part 2 and 3 load stage 10 in the FZG (DIN 51354). Incorporating the super high viscosity index of the Stabilized* High Oleic Base Stocks (HOBS) into the formulas, gives multi-grade synthetic base oils performance by boosting the viscosity index to synthetic levels (Energy Conserving Formulas). An environmentally friendly, zinc-free additive system has also been developed that meets or exceeds high pressure pump requirements.
Fire Resistant Performance: The super high viscosity index of the HOBS naturally improves the thermal shear stability of the formulas and their load capacity. The HOBS’s extremely low volatility (NOACK <1) and excellent oxidation stability improves the flash and fire safety features in these formulas. In ASTM D-92, Flash Points range from 532°F (278°C) to 536°F (280°C) and Fire Points range from 635°F (335°C) to 644°F (340°C). Based on previous test results, HVO Hydraulic Fluids ISO 46 (FR) and ISO 68 (FR) can be Factory Mutual approved as less hazardous fluid “Specification Tested” ISO/CD 15029-3 rating (HFDU), and ISO/TS 15029-2 Spray Ignition-Ignitability (Class H). The tests have supported the expected temperature ranges of Autoignition (ASTM D-2155) @ 752 – 815°F (400 – 435°C) and Manifold Ignition (ISO 20823) @ 824 – 896°F (440 – 480°C).
Bio-HVO™ Hydraulic Fluids meet the Environmental Protection Agency (EPA) 2013 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. They exceed the acute toxicity (LC-50 / EC-50 >1000 ppm) criteria adopted by the US Fish and Wildlife Service and the US EPA. Because they meet the environmental requirements they can also be used where ISO 15380 HEES (unsaturated) or HETG Hydraulic Fluids are specified. Bio-HVO™ Hydraulic Fluids are ENVIRONMENTALLY ACCEPTED LUBRICANTS (EALs) that are formulated from renewable agricultural biobased resources. We believe Earth’s environmental future rests in the use of renewable materials.
