55% DROP


This Healthcare Facility relied on an analog cooling tower control system with no real-time conductivity and minimal calibration ability. Cooling water treatment chemicals were added continuously, without automatic adjustment for variable heat load. Biocide was added manually with a pre-set timer limiting the effectiveness of biological control.


All three control panels were replaced with a web-capable controller platform with fully automated chemical addition, real-time readouts, data logging of makeup, conductivity, and inhibitor levels, and remote alarming. After upgrading the equipment, this facility switched to a more efficient chemical, AQUAGUARD 508, and adopted alternating biocides with different dose rates for improved biological control.


Reduced Chemical Usage

New improved chemistry, stability and control, resulted in reduced chemical usage, substantial cost savings, and better biological control.

Break-Even ROI in only 10 Months

Equipment upgrades and water treatment program changes resulted in significant reduction of chemical use and $8000 in annual program savings.

  • Scale and corrosion inhibitor volume reduced by 80%
  • Biocide volume reduced by 45%
  • Water treatment chemical operating cost reduced by 55%
