Deliver peak performance in extreme conditions

With a higher autoignition temperature and greater heat release compared with traditional mineral oils, Shell Fire-Resistant Hydraulic Fluid S2 DU reduces the risk of fluid ignition and is ideally suited to operating environments subject to fire hazards, such as steel mills, surface mines, foundries, tunnel boring and other metal, mining and glass industries.

Shell Fire-Resistant Hydraulic Fluid S2 DU is a versatile fluid designed to reduce fire risk and enhance system efficiency and hydraulic equipment wear protection across a range of challenging operating environments

Excellent cleanliness and filterability characteristics, and excellent water separation, air release and anti-foaming properties help to keep hydraulic systems clean and running smoothly, even if the fluid is contaminated with water.

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 S2 DU is engineered to work in a wide range of settings and has been designed with the environment in mind

• It is classified according to OECD and EPA water-accommodated fractions test guidelines as “not harmful” to bacteria, algae, freshwater and marine invertebrates, and fish.
• The fluid is also readily biodegradable (more than 60% broken down after 28 days in the OECD 301 B carbon dioxide evolution test)
• And contains a mean biobased content of over 80% (ASTM D6866).

The low toxicity of Shell Fire-Resistant Hydraulic Fluid S2 DU, when compared with mineral oils, makes it particularly suited to environmentally sensitive areas where fire hazards are also a concern. These include industrial, marine and mobile applications.

Lower operating costs and reducing downtime

Shell Fire-Resistant Hydraulic Fluid S2 DU provides anti-wear and film strength properties necessary for hydraulic systems under moderate to severe conditions. Shell Fire-Resistant S2 DU advanced ashless and zinc-free anti-wear additives protect against operational wear:

• As proven in Eaton Vickers 35VQ25 vane pump and Komatsu HPV35+35 high-pressure piston pump tests.
• Shell Fire-Resistant Hydraulic Fluid S2 DU has lower wear compared with the Eaton Vickers V104C pump test limit (ISO 20763) and provides better wear protection than industry standards and mainstream mineral oil hydraulic fluids.

Improving Air release - Air in the oil can lead to undesirable consequences such as reduced efficiency and responsiveness and increased likelihood of erosion, cavitation or other harmful system issues that can cause unplanned downtime and increased maintenance costs.

•  Shell Fire-Resistant Hydraulic Fluid S2 DU exceeds equipment manufacturers’ air release limits.

Designing fire-resistant hydraulic fluids with reduce wear protection and improve air release helps to extend the life of components and service life of your equipment. It improves the efficiency of your hydraulic systems and keeps them running for longer.
