Features & Benefits

  • 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.
