It takes several years to completely bring new power plants online. One way to achieve more power immediately is to boost the heat rejection capacity of cooling ponds, sprayer ponds, and canal returns.

RWI Enhanced Evaporation has developed a floating cooling tower, Hydracool, to increase the heat rejection capacity of cooling and sprayer ponds. High efficiency cooling fans are used to reduce parasitic loading. Droplet size control supports maximum cooling while reducing the need for make-up water.

Hydracool provides a pumping rate of 250 to 400 gallons per minute. These units are available in sizes from 6 tons to 30 tons capacity. One such floating unit is usually enough to provide auxiliary pond cooling of 2,700 tons per hour.

They can be deployed as temporary or permanent installations. However, during the summer, at the very time demand is at its highest, many facilities can’t operate at 100% capacity – so multiple units may be required.

The RWI Hydrocool floating cooling tower represents an upgrade to the heat rejection capacities of sprayer ponds, cooling ponds, and cooling return canals. There is no need for expensive foundation engineering, geotechnical evaluation, or foundation construction.

It provides a simple way to increase generation capacity by adding more heat rejection to the surface of pre-existing sprayer ponds, impoundments, cooling loops and cooling canals. And is available in sizes from 11 million Btu per hour to 200 million Btu per hour size.
