Tp-22B

The specification:
Structure: It is produced from paraffinic petroleums with clearing application by selective solvents. Contains the additives improving antioxidizing, anticorrosive and demulsifying properties. In comparison with oil Tp-22S possesses the strengthened antioxidizing properties, the big service life, smaller propensity to sediment formation at work in the equipment.

Scope: has no substitutes among domestic grades of turbine oils at application in turbocompressor large manufactures of ammonia.
