The Aero-clean aerospace parts washer is designed to clean the complex parts typically found in high-technology industries such as aerospace, and any other industries in which parts with internal passageways, metal folds, blind holes in multiple orientations or other complex detail is found. This cleaning system includes the features necessary to produce zero-residue cleaning results and high-volume capabilities by:

• Utilizing the Advantage automation system design to maximize ultrasonic performance and provide through-the-surface agitation during processing in each liquid tank (patent pending).
• Including Zenith’s patented Crossfire Multiple Frequency Ultrasonic System (US patents 5,865,199 and 6,019,852).
• Adding a 2-position dryer tunnel to provide high-volume cleaning.
• Including features which prevent floating contaminants such as oil and particles from re-depositing on parts being cleaned.
• Providing capabilities to eliminate air pocket entrapment which may prevent ultrasonic cleaning in these areas.
• Automatically controlling rinse water quality to ensure zero-residue cleaning results.

This aerospace parts washer is fully loaded with additional features, all of which are designed to provide the best quality and highest-volume output of any competitive cleaning system design.

The features detailed above provide several unique benefits:

• Using the Advantage automation system, baskets are supported from overhead. By eliminating support structures below the basket which absorb enormous amounts of ultrasonic energy, parts are cleaned faster and more effectively.
• Since parts can be agitated through the surface of the fluid, cavities, blind holes, and other detailed areas of parts are filled and drained repeatedly which serves to flush loosened contaminants from these areas and improve air pocket release.
• Since the drying cycle is typically long in any aqueous ultrasonic cleaning operation, it tends to dictate how many baskets are processed in a given time frame. By including a 2-position dryer tunnel, the drying bottleneck is eliminated.
• When parts are lifted from the ultrasonic cleaning tank, any floating contaminants can re-deposit onto parts. This aerospace parts washer provides features which remove these floating contaminants before parts are lifted from the tank.
• In many cases, parts cannot be positioned in a position which releases all air from blind holes and other detailed areas. These pockets will prevent ultrasonic cleaning in these areas. The Aero-clean design includes the capability to release these air pockets to ensure consistent cleaning results.
• Rinse water quality will determine whether or not parts eject from the system completely spot-free. The Aero-clean includes features which control rinse water quality automatically to ensure that parts are ejected perfectly clean each and every time.
• Crossfire Multiple frequency Ultrasonics are included to maximize the range of particle sizes addressed by the system, and provide the scrubbing power of low frequencies with the penetration and even energy distribution of higher frequencies.
