Refrigeration

An beverage processor constructed a new “State of the Art” refrigerated warehouse (15,000 tons of refrigeration) and wanted to reduce water usage, lessen environmental impact, improve worker safety, and also wanted low overall operating cost.

Three CHC 250-GPM units and a high-capacity automated filtration system were installed in January 2003. The new condensers were passivated during initial start-up of the system.

Frequent visual inspections and compressor head pressures showed no scale formation. Corrosion rates were less than 3.0 mpy for mild and galvanized steel, and less than 0.3 mpy for stainless steel. Bacteria counts were 50% less than other systems at the same facility still under chemical treatment.

The customer is saving over 5.4 million gallons of water annually, with cost savings exceeding $100,000 per year. The customer has the ability to reuse 2 million gallons of non-potable water per month.
