Castrol Cyltech ACT

Crosshead Engine Cylinder Lubricant

DESCRIPTION

Castrol Cyltech ACT (Ash Control Technology) is a premium marine diesel engine cylinder lubricant specifically
developed to provide protection when using low sulphur fuels and LNG.
With a low ash content, the product provides optimum protection against potential ash deposits that may be formed as a
consequence of using low sulphur fuels with traditional lubricants of a high ash (or high base number (BN)). The low
ash content is achieved by a careful balance of low BN additives that also succeed in maintaining piston ring zone
cleanliness.

APPLICATIONS

Cyltech ACT is suitable for the cylinder lubrication of all crosshead engines burning low sulphur fuels that comply with
current IMO Emission Control Area (ECA) legislation where a maximum sulphur content of 0.1% (1,000 ppm) is
mandated. It is also suitable for other low sulphur and zero sulphur fuels such as natural gas.

ADVANTAGES

If high BN lubricants (with high ash content) are used for extended periods when burning low sulphur fuels, there is a
tendency for ash deposits to build up on the piston and in the exhaust system and turbochargers. Use of Cyltech ACT,
as a low ash lubricant, effectively mitigates this potential problem.

  • Reduced potential for ash deposition on engine components
  • Reduced risk of cylinder bore polishing as a consequence of ash deposits rubbing on the liner
  • Maintains a clean piston ring zone, keeping rings free to move in the grooves
  • Extends the durability of the engine when using low sulphur fuels for extended periods
