A retirement home in Virginia was experiencing heavy scale deposits in their 500 ton cooling tower, significantly increasing the energy costs to operate the unit. In fact, it was costing the company over $23,000 per year in addition to the normal costs of operating a clean, efficient unit. Due to the heavy scale, 400 gallons of RYDLYME was recommended to clean the tower. The product was circulated for 12 hours, water flushed, and returned to service. The $7000 investment of RYDLYME material and labor realized a payback period of 3.5 months, and significantly improved the cooling efficiency of the system.
