Precision Cleaning during Aircraft Maintenance

Tovatech's Ultrasonic Cleaners fulfill the stringent demands that operational safety standards require for aircraft parts cleaning. 

Precision Cleaning of Aircraft Parts with Ultrasonic Cleaners

  • Cleans all types of aircraft parts including generators, brakes, actuators, shuttle valves, filters, engine blades and vanes, aircraft wheels, and bearings
  • Cleaning results equal to or better than traditional solvent cleaning methods
  • Avoids harmful metal loss or erosion of base metal surface or potential of surface defects with sand blasting
  • Uniform cleaning process delivers consistent results every time
  • Increases lifespan of component due to less aggressive cleaning mechanism
  • Usually a single step process with  no manual intervention

Precision cleaning of your aircraft components is an operational safety requirement – a matter of life and death.  Parts need to be thoroughly prepped to meet stringent aviation safety norms.  Cleaning being an important element in this process requires special consideration.  Traditional cleaning methods are labor intensive and inconsistent.  Parts that require cleaning typically require pretreatment before being subjected to an aggressive cleaning regime that could involve water or sand blasting.  This can decrease the life of the component material and in some cases even damage the surface.

Ultrasonic cleaning is a revolutionary approach to cleaning that drastically reduces the cleaning time while improving the quality of the cleaning action.  The cleaners work on the principle of agitating aqueous or semi-aqueous cleaning solvents using high frequency sound waves.  With ultrasonic cleaners, parts cleaning is a batch operation.  This saves hundreds if not thousands of person-hours as compared to the traditional process where each part requires individual attention. 

The ultrasonic agitation creates millions of microscopic bubbles that implode releasing vast quantities of energy.  This implosion or cavitation rapidly increases the local temperature releasing a highly energetic jet of liquid that collides with the surface of the object being cleaned.  Ultrasonic cavitation along with the properties of the cleaning chemistry results in micro-scrubbing of the soiled parts.

While ultrasonic cleaning is the perfect deep cleansing solution for aircraft parts, choosing the right combination of cleaner and cleaning chemistry can get a bit tricky.  There are several gotchas you need to know.  Aircraft parts come in a variety of materials: aluminum, stainless steel, carbon steel, high strength alloys, copper and ceramic are all found in aircraft.  The right combination of cleaning unit and chemistry, and the operating temperature and frequency need to be determined to ensure you get the best out of your investment in ultrasonic cleaners.  This is where we come in.  Call us and we will help you select the right cleaner and a matching chemistry for your aircraft component cleaning needs.
