Customer Background

The customer is a global supplier of automobiles, power equipment, engines, marine equipment, and more. There are twelve manufacturing plant locations in the United States alone.


The customer needed a washing system to clean various sizes of plastic pallets which are used in their manufacturing processes, so that clean components would not be re-contaminated. The pallets were soiled with dirt, dust, chips, and oils, and needed to exit visually clean and with a cleanliness specification for particle mass.


Alliance provided an Aquamaster CB-1400D, a belt-style parts cleaning system designed for tall-profile dunnage and pallets. This washer includes a wash and ambient blowoff zone, plus a dual mist collector system, micro-filtration chamber with contamination sensor, product shutdown timer sensors for the load and unload ends, a chemical injection system for the wash solution, and a 4″ wide belt-type oil skimmer to remove floating oils. On each side of the conveyor, product guides help guide the tall pallets through the wash system.

Cleaning Method

Aqueous cleaning was ideal for this application because the parts are large in profile and require general spraying to remove the contaminants.
