Midi Parts Washer Achieves Highest Aerospace Cleanliness Standards

Ideal for cleaning applications within a centralized layout, the Midi with its standard size cleaning chamber measures just 65” (W) x 110” (D) x 89” (H), so it occupies a relatively small footprint, particularly on its front face.  For components that are very long, the Midi’s wash chamber can be extended to as long as 60”. This highly versatile single chamber rotational cleaning system features degassed ultrasonic wash & rinse, immersion wash & rinse, spray wash & rinse, hot air dry, and vacuum dry for complex components.  Proven MecWash aqueous technology cleans without solvents or emissions and is effective for large and small components, components with complex geometries, components that require special fixturing, as well as standard size baskets that can hold high volumes of components per cleaning cycle.

The Midi wash chamber can be configured with hundreds of high volume jet nozzles, which thoroughly penetrate and saturate the workload at a rate of 130 gallons per minute.  Full rotation of the workload at between 2-10 RPM exposes all surfaces to the wash and rinse solutions to ensure effective cleaning, draining, and drying.  Alternately, delicate components can be cleaned using a program setting of oscillation, which gently tips the components from side to side.

For complicated components with extremely high cleanliness requirements, the degassed ultrasonic wash process is followed by a flood and spray wash, an ultrasonic rinse, a flood and spray rinse, and a high velocity hot air dry cycle. If necessary, a vacuum dry cycle can follow the hot air dry. Vacuum drying is effective for pulling water out of blind holes and long machined passages where water may otherwise be retained due to capillary effect. Total cycle times range between 3 - 20 minutes, depending on the specific components to be cleaned. Lastly, for companies concerned about using a water-based cleaning process to clean iron and steel components, MecWash aqueous chemicals are uniquely formulated with rust inhibition to prevent corrosion for up to two weeks after cleaning, regardless the season.

“The Midi technology is proven in companies like Rolls-Royce Aerospace, UTC Aerospace, GE, Parker, Eaton, and others” said Bill Westbrook, North American Operations Manager for MecWash Systems, “so we’re excited to bring it to the North American marketplace.  With the MecWash Midi, companies in demanding industries like aerospace, automotive, hydraulics, medical and defense meet and exceed the highest cleanliness standards. With the MecWash Midi, companies can also realize significant cost savings in both labor and materials as they pertain to their specific cleaning operations.”

MecWash Systems offers a complete line of aqueous cleaning equipment proven effective for the most demanding cleaning applications in the aerospace, automotive, hydraulic, pneumatic, medical, and precision machining industries. MecWash cleaning systems can be found in the manufacturing facilities of some of the world’s most respected companies including Rolls-Royce Aerospace, UTC Aerospace, TRW, Caterpillar, Delphi, Eaton, SKF, GE, Parker, SPS Technologies, Triumph, and Woodward.
