Castrol Anvol CF 22

VISCOSITY - ISO 46

Fire resistant hydraulic fluid

DESCRIPTION

The Castrol Anvol™ SWX grades are HFDU synthetic polyol ester type hydraulic fluids for use in applications that require a
high degree of lubricity and fire resistance according to Factory Mutual Category 1. Anvol SWX products are outstanding in
their category in providing a safe working environment and improved system reliability.

APPLICATIONS

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

Anvol SWX 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 provides safety, protection and reliability. This has the added value
of reducing failures and minimising unscheduled downtime.

Anvol SWX 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.

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

Anvol SWX grades meet the requirements of: Factory Mutual Category 1

 

ADVANTAGES
  • High fire point provides superior fire resistance characteristics which creates a safer working environment and
    greater equipment protection.
  • Anvol SWX 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

Unlike some HFDU products Anvol SWX 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 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.
