Applications

 N/A Formulated to work in high pressure hydraulic systems up to 7500psi Anvol SWX 68 provides all types of hydraulic pumps with protection against wear equivalent to that of mineral oils.

Anvol SWX 68 is designed to combine HFDU 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.

Even in the harshest steel mill environment, Anvol SWX 68 provides safety, protection and reliability. This has the added value of reducing failures and minimising unscheduled downtime.

Anvol SWX 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 Anvol SWX 68.

Anvol SWX 68 is a fully compatible with nitrile (NBR), hydrogenated NBR and fluropocarbon rubbers (FKM). The Seal Compatibiltiy Index is comparable to mineral oils.

Anvol SWX 68 meets the requirements of: Factory Mutual Category 1

Features and Benefits

 N/A
  • High fire point provides superior fire resistance characteristics which creates a safer working environment and greater equipment protection.
  • Anvol SWX 68 is shear stable and fire resistant properties are maintained during use.
  • Advanced corrosion inhibition protects ferrous components from residual water and leads to extended 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.

Additional Information

 N/A Unlike some HFDU products Anvol SWX 68 does not use polymeric materials in order to pass spray ignition type tests. These polymeric materials can rapidly shear in service and this leads to a loss of the claimed spray test performance and also to a significant reduction in viscosity. The selection of Anvol SWX 68 for use in a hazardous environment should be based on its high fire point and lower calorific output (based on Factory Mutual Group 1 classification). A risk assessment should always be carried out whenever there is a need to select any type of fire resistant hydraulic fluid, based on factors such as the potential sources of ignition, fire prevention measures in place and potential consequences of a fire.
