High Performance Hydraulic Fluids - HYDRAUNYCOIL 


HYDRAUNYCOIL range of products includes standard high viscosity index - HV type - fluids (FH 4040 & FH 4050 ), biodegradable hydraulic fluids based on vegetable oil (NX 40304), polyoleates (FH 42xx series) and top tier fluids based on special esters showing high oxidation stability for improved drain intervals (FH 44xx series).

Less flammable biodegradable - HFDU type - hydraulic fluids are also available (FH 4541 & FH 4551).

Some other special hydraulic fluids have also been developed for specific applications. They are intended for instance, for equipments working at very low temperature or specifically developed to meet particular requirements like off shore engineering equipments (downhole devices)
