Product Description
Coomcool HFDU 68 is synthetic polyol ester type hydraulic fluids. The products is providing a safe working environment and improved system reliability.
Advantages
- High fire point provides superior fire resistance characteristics which creates a safer working environment and greater equipment protection.
- Shear stable and fire resistant properties are maintained during use.
- Advanced corrosion inhibition protects ferrous components from residual water and leads toextended equipment life and reduced downtime.
- Excellent resistance to oxidation and thermal degradation reduces sludges, varnish and prevents valve sticking. This ensures longer system life and longer drain periods.
- Good antiwear performance gives excellent wear protection and reduces downtime from unscheduled maintenance.
Applications
Coomcool HFDU 68 is used in areas of the manufacturing industry were there is high risk of fire such as hot strip mills, coil handling facilities, pipe mills and continuous casters. The risk is minimised by the high fire point and the low heat of combustion of it.
Coomcool HFDU 68 is designed to combine fire resistance performance with superior system reliability and a reduced tendency to form varnish or sludge in valves, pipes and reservoirs. It also provides greater resistance to water by offering high levels of corrosion protection.
