Is the blowdown amount of the cooling tower appropriate? Concentration management through continuous measurement of conductivity (EC).
For the management of concentrated circulating water and spray water, as well as the adjustment of blow-off volume. We introduce blow control tailored to water quality utilizing continuous conductivity measurement.
Do you feel any challenges regarding the adjustment of blowdown volume and concentration management for the circulating water and spray water in cooling towers? In open cooling tower circulating water and closed cooling tower spray water, soluble components become concentrated due to water evaporation. As concentration increases, the risks of scale deposition and corrosion rise, making proper blowdown management essential. On the other hand, excessive blowdown leads to increased usage of makeup water and water treatment chemicals. Therefore, management according to the water quality condition is required. ■ Improving blowdown control efficiency through continuous conductivity measurement By continuously measuring conductivity, you can grasp the concentration trends of soluble ionic components in the water and utilize this for blowdown control based on set values. This allows for operational management that responds to changes in water quality, rather than relying solely on periodic blowdowns or manual adjustments. One of the devices that can be used for conductivity monitoring and blowdown control in cooling towers is the water quality monitoring controller "HI 520." 【Features】 ■ Modbus/RS485 compatible ■ 4-20mA analog output ■ Up to 5 relay contacts ■ Can connect 2 sensors to one main unit *For more details, please download the PDF or feel free to contact us.
