Applications

 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 Turbo S5 DR 46 is a high-performance phosphate ester self-extinguishing fire-resistant fluid, offering high flash point and high auto ignition temperature. It minimizes the risk of fire, which could potentially be caused by mineral oil products.

Good Oxidation Stability - To provide long service life under normal operating conditions.

Good Hydrolytic Stability - Shell Turbo S5 DR 46 is to a great extent able to withstand rapid decomposition of the base fluid under the influence of moisture and water in the oil system.

Good Demulsibiliy - To enable rapid separation from water for improved service intervals.

Controlled Air Release - Good air-release minimizes air entrainment in lubrication and governor control systems in order to ensure safe operation of the whole equipment.

Low Foaming - Minimal tendancy for foaming to provide proper lubrication and heat transfer.

HSSE - Shell Turbo S5 DR 46 is an advanced low toxicity fire-resistant hydraulic fluid that is trixylenyl phosphate (TXP)-free and is designed specifically to comply with future EU REACH regulations for use in EHC systems. It is a fully formulated fluid based on tert-butylphenylphosphate.
