HOW it works
PR - PRE-RInse
For applications with heavier soils, items first move through an optional pre-rinse section to loosen and remove product residue before detergent cleaning.
DW - Detergent Wash
The detergent wash section uses heated cleaning solution and high-impact spray to loosen and remove remaining soils.
RR - Recirculating Rinse
The recirculated rinse removes most residual detergent from the items. Where a pre-rinse section is included, rinse water can overflow into the pre-rinse section for reuse.
FR - Fresh Water Rinse
Fresh water removes the remaining detergent film. The rinse can also support a final hot-water or chemical sanitizing step.
BL - Optional Blow-Off
An optional exit blow-off system can remove some of the residual water left on items after the final rinse.
