Water Savings

Cooling system blowdown can account for as much as 50% of the total system fresh water use. Increasing cooling system cycles of concentration reduces blowdown and can result in significant water savings.

For example:   A 500 ton system operating at 2 cycles of concentration loses 21,600 gallons of water per day to blowdown. Increasing cycles of concentration to 5 reduces blowdown losses from the system to 5,400 gallons per day.  This represents a savings of 16,200 gallons per day or almost 6 million gallons per year!

Our EV Series technologies allow systems to operate at higher cycles of concentration.  This saves water and reduces chemical consumption.
