Fire Resistant and Readily Biodegradable Hydraulic Fluids HFDU/HEPG
EcoSafe® FR fluids represent a significant advancement in fire-resistant hydraulic fluid technology. These fully synthetic formulations deliver performance superior to premium anti-wear mineral oils and offer significant performance and environmental advantages over other fluid options – including other synthetics. EcoSafe® FR fluids are used in industrial and mobile equipment, including high-pressure systems, hydrostatic drives, systems with servo valves, and all robotics.
EcoSafe® FR fluids are based on a very high VI, polyalkylene glycol (PAG) base stock combined with a non-metallic additive package. Unlike phosphate ester and polyol ester (including fully saturated synthetic ester) based fluids, they do not break down when exposed to water, minimizing the potential for fluid degradation and system damage. As a result, fluid change-out intervals are extended under even the most severe operating conditions.
EcoSafe® FR fluids are classified as FM Approved industrial fluids by Factory Mutual, and meet classification requirements of fire-resistant according to DIN/EN/ISO DIS 12922. FR-68 complies with the requirements of SEB 181 223 for the German Steel Industry (VDeH).
Excellent Lubricity – EcoSafe® FR fluids offer excellent lubricity, for exceptional pump life under the most severe conditions. The fluids meet or exceed the pump performance of premium, anti-wear mineral oils, even at 5,500 psi (380 bar) operating pressure. Shear stability is excellent. And all three grades earn a 12-stage rating in the FZG Gear Test, demonstrating high-level protection against wear and scuffing.
Non-Sludge or Varnish Forming – EcoSafe® FR hydraulic fluids are oxidatively stable and will not degrade to form varnish or sludge, contributing to long-term system cleanliness while extending maintenance intervals and overall service life.
