Shell Fire-Resistant Hydraulic Fluid S3 DU

Deliver peak performance in extreme conditions

Operating in severe conditions presents your hydraulic systems with additional performance challenges, meaning the lubricants you use need to provide optimum protection at wide temperature ranges.

From protection against cavitation in cold start-ups to extra durability in extreme heat, Shell Fire-Resistant Hydraulic Fluid S3 DU helps keep your hydraulic systems operating productively under these conditions.

• Inherently fire-resistant, Shell Fire-Resistant Hydraulic Fluid S3 DU improves the safety of your operations with a high flash point, high fire point and a high auto-ignition temperature to minimise the risk of fire.
• Shell Fire-Resistant Hydraulic Fluid S3 DU provides outstanding pump life under severe conditions – delivering excellent shear stability and high levels of protection against wear and scuffing.
• Combining high viscosity with excellent low-temperature fluidity, Shell Fire-Resistant Hydraulic Fluid S3 DU provides year-round protection for your equipment – keeping it running smoothly.

Protect your equipment and the environment

When operating in environmentally sensitive settings, you need to know that your hydraulic fluids are not only able to protect your equipment but also help you to mitigate any impact on local ecosystems.

Shell Fire-Resistant Hydraulic Fluid S3 DU is engineered to work in a wide range of settings and has been designed to help you meet your environmental responsibilities.

• Designed to be readily biodegradable, Shell Fire-Resistant Hydraulic Fluid S3 DU with ISO viscosity grades 46 and 68 give you greater peace of mind across applications in environmentally sensitive areas.
• Shell Fire-Resistant Hydraulic Fluid S3 DU is recognised by FM Global as an inherently fire-resistant industrial fluid, suitable for high-pressure systems where fire hazards are a concern.
• Shell Fire-Resistant Hydraulic Fluid S3 DU 46 has a biodegradability of more than 60% after 28 days in the OECD 301 B carbon dioxide evolution test.

Lower operating costs with longer service life

Hydraulic systems operating in severe conditions often require shorter maintenance intervals. Fluid degradation reduces the service life of lubricants and forces you to replace them more often.

Shell Fire-Resistant Hydraulic Fluid S3 DU is engineered to minimise fluid degradation and extend fluid changeout intervals – even under the most extreme conditions.

• Shell Fire-Resistant Hydraulic Fluid S3 DU helps to extend the life of equipment and requires less frequent changeouts than mineral oil-based fluids. In many cases, this fluid can be used four times longer than non-synthetic fluids.
• Shell Fire-Resistant Hydraulic Fluid S3 DU is developed to provide high resistance against sludge and varnish, keeping your hydraulic system cleaner for longer and reducing the need for maintenance.
• Unlike phosphate esters, polyol esters and vegetable oils, Shell Fire-Resistant Hydraulic Fluid S3 DU will not react with water, thereby minimising the fluid degradation and acid formation that can damage and eventually destroy hydraulic pumps.

This lowers your consumption and helps to reduce your operating costs in comparison to mineral oil-based fluids.
