Shell EcoSafe S3 DU 46 can be used as the hydraulic fluid in industrial and mobile equipment, including high-pressure systems, hydrostatic drives, systems with servo valves, and robotics.

N/A Formulated to work in high pressure hydraulic systems up to 7500psi Anvol SWX 46 provides all types of hydraulic pumps with protection against wear equivalent to that of mineral oils.

Anvol SWX 46 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 46 provides safety, protection and reliability. This has the added value of reducing failures and minimising unscheduled downtime.

Anvol SWX 46 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 46.

Anvol SWX 46 is a fully compatible with nitrile (NBR), hydrogenated NBR and fluropocarbon rubbers (FKM). The Seal Compatibiltiy Index is comparable to mineral oils.

Anvol SWX 46 meets the requirements of: Factory Mutual Category 1

N/A Hydraulic Fluid - It can be used as the hydraulic fluid in electrohydraulic governor control (EHC) systems in steam and gas turbines.

Lubrication of Steam and Gas Turbines - Shell Turbo S5 DR 46 can also be used as the lubricating oil for main bearings in steam and gas turbines, generators and cooling pumps. As a precaution, its compatibility with system components should be confirmed. 
Features and Benefits N/A

Excellent Fire Resistance - Shell EcoSafe S3 DU 46 is inherently fire-resistant and is FM approved, offering high flash point, high fire point and high auto-ignition temperature. It minimizes the risk of fire, which could potentially be caused by mineral oil products. 

Enhanced System Protection - Shell EcoSafe S3 DU 46 offers excellent lubricity, for outstanding pump life under the most severe conditions. The fluid meets or exceeds the pump performance of premium, anti-wear mineral oils, even at 5,500 psi (380 bar) operating pressure. Shear stability is excellent. Shell EcoSafe S3 DU 46 achieved a 13-stage rating in the FZG Gear Test demonstrating a high level of protection against wear and scuffing.

Good Hydrolytic Stability - Shell EcoSafe S3 DU 46 will not brekad down and react with water, minimizing fluid degradation and acid formation that can damage and eventually dstroy hydraulic pumps. No acid removal/ion exchange filters are required. 

High Resistance to Sludge or Varnish Formation - Shell EcoSafe S3 DU 46 is formulated to provide high resistance against varnish and sludge formation. Field experience has shown long-term system cleanliness while extending maintenance intervals and service life. In addition, this fluid is very stable at high temperatures and resistant to thermal degradation up to 120 C. 

Suitable for All-Weather Service - A high viscosity index in combination with excellent low-temperature fluidity provide year-round fluid that portects the machine from cavitation at cold startups and provides durability at higher operating temperatures.

Excellent Compatibility - While Shell EcoSafe S3 DU 46 is compatible with many different types of fluids, to ensure proper system performance, it is recommended to properly clean and flush hydraulic systems during conversations. Shell EcoSafe S3 DU 46 is compatible with commonly used seals, hoses and metals.

Additional Information N/A N/A Unlike some HFDU products Anvol SWX 46 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 46 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.
