Tarmond HyFlo Safe HFDU 46 is an environmentally responsible hydraulic fluid offering inherent fire resistance thanks to its synthetic ester structure. Its fully bio-based, sulphur/chlorine-free formulation prevents the formation of toxic by-products. It provides strong protection against wear, oxidation and corrosion while controlling foam formation. Designed for heavy-duty, high-temperature applications such as casting lines, blast furnaces and hot rolling mills, it delivers safe, stable and long-lasting hydraulic performance. It is an ideal solution where mineral oils or water-glycol fluids are not suitable.
