Aqueous
Parts Washers:
Case Study
A steel mill had been cleaning 42 inch roller bearings by boiling them in fuel oil for 6-8 hours in a 300 gallon vat. This was followed by manually scraping and brushing to remove the high temperature grease used in the bearing. They installed a spray washer (80 gpm, 75 psi, 160 F) as an alternative. The spray washer cleans the bearing in 15 minutes and gets it cleaner than the old method. The cost of the spray washer was returned to the company in 6 months in labor savings alone. As a result of installing the new washer they are cleaning the bearings more often (prolonging bearing life), and have eliminated a significant safety hazard.
