Meet European industrial discharge specifications;US and UK defense standards

'Green' compressor wash fluidsare environmentally friendly

ZOK International Group. long-timesupplier of industrial and marine.

aero and aeroderivative gas turbinecompressor and cleaning fluids, isintroducing a new product that theysay is aimed at especially difficultcleaning requirements.

New 'ZOK mx' cleaner is based onan environmentally-friendly formula­tion and is being marketed in parallelwith the group's long-standing ZOK27 compressor wash and inhibitor.Both fluids are formulated to meetEuropean industrial and UK and USdefense department standards.

Traditionally, compressor cleaningfluids use alkyl phenol ethoxylateslAPEs) in their fortnulations--<:hemi-

cal compounds suspected as causingproblems in fish. Both of the ZOKfluids use alcohol ethoxylates in theirplace. "These degrade faster thanAPEs and obviate their toxicityphase." says ZOK's Keith Cartwright.

"Removing APEs from their formu­lation enables our products to satisfythe requirements of the EU's Oslo andParis (OSPAR) Convention for pre­vention of pollution in nonhernEuropean warers." he notes. "This hasbeen achieved three years ahead ofOSPAR taking legal effect."

New ZOK mx is being marketed asa biodegradable. non-hazardous. waterbased cleaning fluid capable ofremoving very stubborn dirt deposits.

"With the recently rewritten MIL-C­85704 specification giving emphasisto cleaning as opposed to corrosioninhibition, the new product is wellsuited to US military engine cleaningrequirements."

On the other hand, ZOK 27 is cer­tificated as a corrosion inhibitingcleaner. Used on smaller turboshaftengines where the small size compres­sor blades need corrosion control­and at th~ other end of the scale wheremanufacturers of large frame industri­al gas turbines specify tight control ofpotassium and sodium trace metals.

Both products are formulated foron-· or off-line cleaning. Washingscheduling can be optimized with thecompany's IPowerWash' software runon your PC control system. The tluidsare available from ZOK [nternat­ional's Airworthy Ltd. in West Sussex.England and ZOK Inc. in Texas. orthrough a worldwide ne[work ofstocking distributors.

DescriptionA concentrated neutral water-based detergentcleaning fluid for cleaning and corrosion inhibitionof gas turbine engine compressors.

ZOK 27" is more effective than standardaqueous cleaners, so it cleans faster. Its non-ioniccJeansing action removes organic contaminantssuch as oil, grease, and hydrocarbons, as well asinorganic fouling such as salts and soil. Anefficient clean is achieved during the very shortcontact times of a hot wash.

DilutionDilute 1+4 with water before use. (20% soiution).Demineralized water «11 ~S/cm conductivity)should be used for hollon-line cleaning.Drinking water «700~S/cm conductivity) may beused for coid/off-line cleaning.A ready-to-use (RTU) version of this product isavailable for users who do not have supplies ofdemineralized water.
