HYDRAULIC FLUIDS, OIL-IN-WATER EMULSIONS HFA Chemical compatibility with O-rings, rubbers, & plastics

Oil-in-water emulsions (HFA) are hydraulic fluids where fine droplets of oil are dispersed in water. These fluids are used primarily in applications requiring fire resistance, such as in steel mills, mining operations, and other heavy industries. The high water content ensures a reduced fire hazard while maintaining adequate lubrication properties. HFAs offer excellent cooling characteristics due to the water content, preventing overheating of hydraulic systems. However, they may require specialized filtration systems to handle the water-oil separation effectively. Proper maintenance is crucial to avoid microbial growth and corrosion, ensuring the system's longevity and performance.
