· 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.
Compatibility & Miscibility
· Compatibility - Packing, seals and hoses
The following materials are recommended for use with Shell Turbo S5 DR 46: Butyl rubbers, Nylon, PTFE, VITON rubber (depending on operation temperature range).
· Compatibility - Paints
Attention must be paid to painted surfaces. Cured epoxy paints are regarded as resistant to Shell Turbo S5 DR 46.
Compatibility - Other fluids
Shell Turbo S5 DR can be mixed in any proportion with other phosphate ester fluids. However, when combining different phosphate ester products, it is always suggested to monitor the performance of the system. The mixing of phosphate ester fluids with mineral oil and polyol esters, polyalkylene glycol and water-based fluids should be avoided. For more information, please consult your Shell Contact.
Performance, Features & Benefits
· Excellent fire resistance
Shell Turbo S5 DR 46 is a high-performance phosphate ester self-extinguishing fire-resistant fluid, offering high flash point, high fire point and high auto ignition temperature. It minimises 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 demulsibility
To enable rapid separation from water for improved service intervals.
· Controlled air release
Good air-release minimises air entrainment in lubrication and governor control systems in order to ensure safe operation of the whole equipment.
· Low foaming
Minimal tendency for foaming to provide proper lubrication and heat transfer.
Shell Turbo S5 DR 46 is an advanced low toxicity fireresistant 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.
