Monitrol is a complete cooling water management program designed to blend state-of-the-art equipment and chemistry into a package to deliver reliable and predictable results to your cooling tower system.

Monitrol Delivers

  • In-line monitoring and control of chemical concentration
  • Real-time corrosion monitoring
  • Customized, scheduled reports
  • Online, real time monitoring and control of all key system parameters
  • Email alarms for instant notification of system upsets
  • Innovative chemistry that provides a system free of scale, corrosion, and biological growth

The Monitrol Difference

Compared to typical cooling tower chemical programs, Monitrol provides several key advantages that increase your level of service, maximize performance, and minimize chemical and water usage.

Typical Chemical Program

Monitrol Program


  • Service only provided at regular intervals
  • Service only provided when Sales Rep is on-site
  • Regular on-site service visits that you are accustomed to
  • Plus, 24/7 online monitoring by your DuBois Representative

Cycles of Concentration

  • Not maximized due to fear of system upsets such as
    • Chemical pump issues
    • Flow issues
    • etc.
  • Due to 24/7 monitoring and e-mail alerts, you and your DuBois Rep receive immediate notification of system upsets
  • This allows system parameters to be set at maximum limits.

Chemical Concentration

  • Fluctuation of +/- 50 ppm from target is typically observed
  • Monitrol controls to within 5 ppm of target
  • Prevents wasteful overfeed of product
  • Also prevents corrosion and scale seen with underfeed of chemistry

Total Cost of Ownership

  • Cycles and chemical feedrate are not maximized
  • Resulting in overuse of chemical and water
  • Underfeed of chemical may result in energy costs due to scale formation
  • Chemical feedrate and Cycles of Concentration are optimized
  • Fewer system upsets due to 24/7 monitoring and alert notifications
  • Results in a clean system free of scale, corrosion, and microbial growth
  • All while minimizing water, chemical, and energy usage
