Description

The Castrol Perfecto X turbine oil range of lubricants is based upon premium quality mineral oils enhanced with rust and oxidation inhibitors to give maximum protection at high temperatures.

Application

Castrol Perfecto X grades are recommended for industrial gas turbines where the lubricant is likely to be exposed to very high localised temperatures. They are also suitable for the lubrication of steam turbines and Combined Cycle generating systems where the steam and gas turbines share a common supply.

Castrol Perfecto X grades possess superior air release performance, good resistance to foaming and excellent water separation properties.

The Castrol Perfecto X range is fully compatible with nitrile, silicone and fluoropolymer seal materials.

The Castrol Perfecto X grades meet the requirements of, or are approved against, the following specifications:

• British Standard BS 489
• DIN 51515 -1 and -2
• GEK 32568g and GEK 107395A (ISO 32)
• Alstom HTDG 90 117 (formerly ABB)
• Siemens TLV 9013 04 and 05
