Clear Development Need
Filterability- In presence of water and
chemical contaminants
Oxidation stability- Improved service life
Corrosion Inhibition- Protection of metal surface
To Meet Evolving Requirements…
Wear protection technology- Extended component life
Hydrolytic stability- Maintains performance
when contaminated with water
Thermal stability- Long service life at high
operating temperatures
Ashless AWHF

Metal-Free / Ashless Additive TechnologyTraditionally ZINC, a heavy metal has been used in anti-wear hydraulic fluid formulations as ZnDTP– Inexpensive lubricant additive,
however not the best solution in terms of various environmental aspects
ASHLESS Technology– Reduces &/or eliminates
substances that have significant aquatic toxicity
– Easily substitutes ZnDTP– Provides better performance
