Abstract: An industrial parts washer having a split canopy for enclosing the processing zones and conveyor system of the washer includes a fixed first section and a selectively removable second section for accessing the internal processing areas of the washer. The removable section of the canopy is optionally constructed as a single piece of material covering all processing zones across the length of the washer, or alternatively the removable section is segmented into two or more subsections which are easily removed and replaced onto the washer by one or two operators. The removable sections of the canopy are releasably attached to the washer with appropriate quick release latches, and the removable section of the canopy is appropriately sealed to the washer to prevent the escape of moisture, steam and chemical contaminants. The canopy is also made of molded fiberglass or plastic materials.
