TotalEnergies Hydransafe HFDU 46 – Fire-Resistant Hydraulic Fluid
Hydransafe HFDU 46 is a fully synthetic, ester-based high-performance hydraulic fluid. It is fire-resistant, biodegradable, and provides excellent lubrication and corrosion protection. Specifically developed for hydraulic systems in fire-prone environments such as steel mills, subways, and underground mining, where water contamination cannot be excluded.
Product Advantages
• Fire-resistant with high auto-ignition temperature (> 420 °C)
• Fully synthetic and biodegradable (OECD 301 B)
• Excellent rust and corrosion protection
• Outstanding lubrication under high loads
• Very high natural viscosity index ensures stable performance across temperatures
• Good flow properties at low temperatures (pour point –42 °C)
• Compatible with mineral- and ester-based fluids
Typical Applications
• Hydraulic systems in fire-prone areas (e.g. steel industry, underground mining, subways)
• Applications where water ingress cannot be excluded
• Recommended for systems from Danieli, Razel-Bec, SMS, Voith Turbo
