Water Filter Reduces Costs at Plastics Plant0 pages

Rehrig aJso manufactures a full line of roll-out carts and bins for curbside collection of household waste and recyclables. The company opթrtes five manufacturing plants located in Califor-nia, Georgia, Kansas.Wisconsin and New Hampshire. Two years ago, Rehrig Pacifies Los Angeles plant was facing production problems caused by clogs in the water pipes used to cool the plastic during the manufacturing process. The cooling towers, located outside in the parking lot, were collecting dirt which was being carried inside the production plant by water that was running through valuable heat exchangers and condensers. "I had to stop production every other week for several hours to clean the lines," said Alfredo Romero, maintenance manager at Rehrig Pacifies Los Angeles plant. "One time, I lost a condenser when it got clogged with dirt, became impacted with ice, and broke off." Romero says a condenser costs about $5,000, but the downtime caused by frquent cleanings was taking an even greater toi] on the com⩭pany s productivity. Rehrig Pacific installed one 4" water filter in the tower. Results were so positive that the company purchased seven more filters for the Los Angeles plant and additional filters for the Georgia, Kansas and Texas plants. Romero now says he no longer lias to worry about dirty water clogging the lines, destroying valuable equipment and interrupting the production process. Contamination of pipes and heat exchange surfaces lowers the thermal efficiency of the System and wastes energy by requiring a higher flow rate of coolͭing water. Contamination also increases friction loss-es by inducing rosion and corrosion. Filtration is one of the simplest and most convenient ways to solve thse problems.
