The CaroMont Health Ozone Laundry System: Energy Savings, Improved Laundered Product Qualities and Return on Investment at Gaston Memorial Hospital, Gastonia, NC

摘要

Ozone-generating equipment was retrofit into the laundry washroom of the Gaston Memorial Hospital in Gastonia, NC, and began operating in the early part of July, 2010. Three ozone-generating systems service six washer-extractors in the washroom. The performance of this fine-bubble ozone diffusion laundering system has been monitored since that time, with various adjustments made to ensure optimum performance and production results. Since installing this ozone system, the laundry has realized $46,000 per year savings in utility costs as well as reduction in water consumption of more than 1,000,000 gal per year, and lower wastewater discharge fees. In addition, the ozone-washed linens are cleaner and brighter than ever and the rewash rate has been reduced by 1.5-2.5%. The apparent Return on Investment (ROI) of this ozone laundering system, calculated on the basis of just these benefits cited, is 16 months.
