Manufacturer's description

Shell Turbo S5 DR 46 is a fire-resistant hydraulic and lubricating fluid made using Tri-Aryl Phosphates based on butylated phenol.

Applications

• Hydraulic fluidIt can be used as the hydraulic fluid in electrohydraulic governor control (EHC) systems in steam and gas turbines.
• Lubrication of steam and gas turbinesShell 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.

Performance & benefits

• Excellent fire resistanceShell 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 stabilityTo provide long service life under normal operating conditions.
• Good hydrolytic stabilityShell 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 demulsibilityTo enable rapid separation from water for improved service intervals.
• Controlled air releaseGood air-release minimises air entrainment in lubrication and governor control systems in order to ensure safe operation of the whole equipment.
• Low foamingMinimal tendency for foaming to provide proper lubrication and heat transfer.
• HSSEShell Turbo S5 DR 46 is an advanced fire-resistant hydraulic fluid, designed for use in EHC systems, with low toxicity to humans. It is free of trixylenyl phosphate (TXP) and fully formulated fluid based on tert-butylphenyl phosphate.
• Shell Turbo S5 DR 46 is approved and/or exceeds the requirements of the major original equipment manufacturers such as General Electric (GEK 46357H), Mitsubishi Hitachi Power Systems (MS-04-CL004, Revision 7), Siemens AG Power & Gas TLV 901202 and TLV901203, and Solar ES 9-224 Revision AA Class IV VG 46
• Shell Turbo S5 DR 46 is FM Approved against Standard 6930 for 'Less flammable hydraulic fluids'. It also meets the requirements of ISO Standard 12922 and ASTM 4293 for HFDR-type fire-resistant hydraulic fluids
