Description
Castrol Perfecto XEP Range 46 – Premium Antiwear Turbine Lubricant
Description: The Castrol Perfecto XEP 46 range of turbine oils is formulated from severely hydrotreated premium mineral base stocks combined with a complex additive system to provide excellent antiwear performance and oxidative stability.
Application: The Perfecto XEP range is primarily intended for the lubrication of highly loaded industrial gas turbines, aero derivative power turbines, driven machinery, and turbo machinery. These lubricants are exposed to high local temperatures during operation and the heat-soaking period during run-down. The Perfecto XEP range possesses the requisite air release, foaming, and water separation properties for steam turbines, making them suitable and compliant for gas and steam turbines in single train sharing a common oil reservoir.
Standards and Approvals: Specific grades within the Perfecto XEP range meet or exceed the requirements of:
- BS 489 1999
- DIN 51515
- General Electric GEK 32568E, GEK 32568G H & J, GEK 101941A, GEK 107395A, GEK 28143A, 46506E
- General Electric Oil & Gas ITN 52220.02, ITN 52220.03
- Alstom HGTD 90117 V
- Siemens TLV 9013 04 & 05
- Solar ES9-224U
- Man Turbo SPD10000494596
Product Performance Claims:
- Meets or exceeds a wide range of both steam and gas turbine specifications.
- Designed for a wide range of applications, making it possible to rationalize grades without the risk of misapplication.
- Excellent thermal and oxidation stability.
- Good water separation and corrosion inhibition performance.
