Water Chemistry Controller

IntelliChem™ Chemical Controller Eco Select

Keep your pool water perfectly balanced with hands-free, automated ease

It can be a challenge to keep the pH and chlorine levels of your pool in constant balance, rather than cycling up and down. The IntelliChem® chemical controller does it automatically by monitoring your pool's pH and sanitizer levels, and delivering just the right amount of chemicals. IntelliChem uses the same technology found in commercial installations, water parks, hotel and community pools. It can work independently, or together with Pentair automation products - so you can check your water chemistry at at glance.


  • Auto Setup/Configuration wizard makes start-up quick and easy
  • Programmable chemical feed cycle and mix times for precise water balance
  • Assures safe water conditions by preventing excess chemical addition
  • Built-in Langelier Saturation Index calculator lets you know if your water is in balance
  • Minimizes chemical costs by adding chemicals with precision
  • Flow sensor ensures chemicals wont feed without system flow
  • Password-protected access prevents tampering or accidental program change
  • Seamlessly interfaces with IntelliTouch®, EasyTouch®, SunTouch® and ScreenLogic® automation systems so its simple to use
