ZOK mx is a concentrated, water-based, non-flammable, environmentally friendly, biodegradable fluid. Specifically developed for heavy-duty cleaning of gas turbine compressors.
Composition: A special blend of non-ionic surfactants, organic solvents and demineralized water.
Appearance: Pale straw colored liquid with a mild, pleasant odor.
Dilution: Dilute 1 to 4 with water before use (20% solution). Demineralized water ((<11µS/cm conductivity) should be used for hot/on-line cleaning. Good quality drinking water (<500µS/cm conductivity) may be used for cold/off-line cleaning. Ready to use (RTU) versions of these products are available for users who do not have access to demineralised water.
Application: By spray ring or lance in either starter-driver (off-line) or fired (on-line) wash as directed by the engine manufacturers, in the quantities recommended in the engine manual. It is essential during hot wash that the cleaner should leave as little ash residue as possible to avoid blocking turbine blade cooling holes. ZOK mx has a maximum ash content of <0.01%, as part of the compliance with OEM specifications for compressor washing fluid.
A water rince and dryout run are both recommended. Antifreeze can be added below 5oC. ZOK mx is compatible with methanol, isopropyl alcohol, and mono propylene glycol (recommended due to its biodegradable nature).
