Deliver peak performance

Hydraulic and fluid transmission systems in exposed environments are subject to wide variations in temperature. The naturally high-viscosity index of Shell Fire-Resistant Hydraulic Fluid S1 DU helps to deliver responsive performance from cold start to full-load heavy-duty operations. Its high viscosity index and shear stability provide consistent viscosity where wide variance in ambient conditions is common.

• The low temperature performance properties enable responsive performance from cold stat to full load heavily duty operations.
• A high viscosity index in combination with robust shear stability provides durability at higher operating temperatures.
• In addition to protecting the machine over a wide temperature operating range, shear-stable, high viscosity index fluids enable increased hydraulic efficiency.

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 S1 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 biodegradable¹ and feature low toxicity, Shell Fire-Resistant Hydraulic Fluid S1 DU can be used in applications across environmentally sensitive areas.
• Shell Fire-Resistant Hydraulic Fluid S1 DU is a USDA-Certified Biobased Product in the USDA BioPreferred programme.
• Shell Fire-Resistant Hydraulic Fluid S1 DU has a high flash point, fire point and autoignition temperature for reduced risk of fire. As an FM Approved Fire-Resistant industrial fluid, Shell Fire-Resistant Hydraulic Fluid S1 is suitable for high-pressure systems where fire hazards are a concern.

Lower operating costs and reducing downtime

Shell Fire-Resistant Hydraulic Fluid S1 DU provides anti-wear and film strength properties necessary for hydraulic systems under moderate to severe conditions.

• Shell Fire-Resistant Hydraulic Fluid S1 DU has lower wear compared with the Eaton Vickers V104C pump test limit (ASTM D 7043) and provides better wear protection than industry standards and mainstream mineral oil hydraulic fluids.
• Excellent anti-wear protection demonstrated in vane pump tests (ASTM D7043) can help achieve lower maintenance costs and less downtime.

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 S1 DU exceeds equipment manufacturers’ air release limits.

Designing fire-resistant hydraulic fluids with reduce wear protection and improved 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.
