How it Works Three-section washers (detergent wash, recirculated rinse and final rinse) are the most commonly requested designs. For heavy residues, a pre-rinse section may be required. Key to Washer Sections: Key to Washer Sections:

Operational overview of 4-section washer with exit blow-off system:









o Washer Sections:

DW - Detergent Wash

PR - Pre-Rinse

Soiled product containers are conveyed through the Pre-Rinse (PR) section to loosen and remove heavy residues. The Detergent Wash (DW) section loosens and sprays off the remaining residue. The Recirculated Rinse (RR) removes most of the residual detergent solutions from the containers and overflows to Pre-Rinse, if available.
