HYDRANSAFE HFDU 68 is an ester-base, high-performance and fire resistant hydraulic fluidHYDRANSAFE HFDU 68 is designed for hydraulic equipments operating in  locations comprising a fire risk, such as iron and steel works (coking plants,blast furnaces, continuous casting), mines, etc. The use of HYDRANSAFEHFDU 68 lessens the serious risks presented by recourse to a mineral oil on theoccasion of rupture of a hose or when a leak gives rise to oil mist, in theimmediate vicinity of a flame, a part in the process of melting or a switchcupboard.HYDRANSAFE HFDU 68 is especially recommended when there is the possibility of contamination of waters : offshore, mines.Advantages:With its considerable fire resistance properties, is associated exceptional lubricating properties which guarantee a substantial reduction in wear, and therefore a longer service life of the hydraulic components. High flash point and high spontaneous ignition temperature. Low pour-point providing good performances at low temperature. Very high natural viscosity index, guaranteeing a viscosity constantly adapted to the temperature range in which the fluid must be used. Very good anticorrosion properties in relation to ferrous and non-ferrous metals making up a hydraulic circuit. Very good oxidation stability: enhanced service life. The product is not expected to produce adverse effects on health. Maximum operating temperature is 120°C.
