What does your cooling tower cost in water?

An evaporative cooling tower quietly draws water and chemicals all year. Enter your figures to see the annual cost, and how much of it is blow-down and chemicals, the part that treatment and higher cycles of concentration can reduce without touching uptime. Nothing is shared until you choose to.

Water-balance assumptions

These are illustrative values you can change. Evaporation rate and cycles of concentration depend on your tower and water; the chemical rate depends on your treatment programme. Enter your own for an accurate figure.

Discuss cutting cooling water See the Data Centres picture

This is an indicative estimate from the figures you enter, not a quote, and it states no saving. It sizes the water and chemicals the tower uses; what could be reduced is assessed and confirmed per site.

How this is worked out

A cooling tower rejects heat by evaporating water, which leaves the dissolved minerals behind. To stop them concentrating, some water is dumped to drain as blow-down, and fresh make-up water replaces both. Evaporation is fixed by the heat you reject and cannot be avoided. Blow-down and the chemicals dosed into the loop are set by how the water is treated and how many cycles of concentration you can hold, so that is the part of the bill that can come down. Raising cycles of concentration safely is one of the most direct levers, with uptime untouched.
