• Recommended for use where high temperature surfaces, flame or other sources of ignition would cause fire in conventional mineral hydraulic fluids, or where the risk of fire due to high pressure fluid release is of concern.
  

Best-in-class fire resistance and equipment protection
 

Synstar Hydraulic HFDU is a highly advanced synthetic hydraulic fluid designed to maximise fire resistance and meets and exceeds 7th Luxembourg Report requirements. The fully synthetic ester based fluid delivers outstanding and highly stable high viscosity index performance and stays in grade in demanding high temperature operations, over a very long service period.Synstar Hydraulic HFDU delivers maximum safety in high temperature operations, where hot surfaces or flame may otherwise be a source of ignition for conventional hydraulic fluids, or where the risk of fire due to high-pressure fluid release is of concern.Synstar Hydraulic HFDU leading edge anti-oxidation additive technologies deliver exceptional performance at elevated temperatures, resisting the formation of sludge and other oxidative products, and allowing for significantly increased system operating pressures and operating sensitivity while significantly improving filter efficiency. 


Super high performance wear protection


Synstar Hydraulic HFDU additive technologies deliver superior protection against shearing and wear over extended operating periods, optimising oil film durability and offering maximum equipment protection in very hot or very wet operations. This advanced fluid provides outstanding hydrolytic stability, and rapid water separation, resisting rust or corrosion formation.
