Product Overview


The Chemtrol 230 ORP Controller is a microprocessor-based digital controller designed to maintain the sanitizer ORP (Oxidation-Reduction Potential or Redox) level of neutral-type sanitizers; i.e., bromine or dichlor that do not require pH control. The Chemtrol 230 is ideal for small commercial pools (apartments, condos or small motels) and high-end residential pools. This unit includes the controller, respective probe, paddle wheel flow switch, and miscellaneous plumbing supplies.

Functions are clearly labeled and accessible from the front panel with safety and easy-reset features not found in other controllers. A bright LCD display shows ORP readings, calibration adjustments and alarm limits. The five LED lights indicate the operating modes (OFF, Manual or Auto), feed status, out-of-range alarms and overfeed alarms. The front panel controls include set point, calibration, low and high alarm limits, safety timer limit and proportional feed adjustment. Feed control is either ON/OFF or Proportional. The Proportional Feed feature is particularly useful to avoid overfeeding in small bodies of water. It reduces the feed cycle time progressively as the sensor reading approaches the set point.

All CHEMTROL controllers are user-friendly, reliable and easy to install and operate. Every unit is supplied with a comprehensive operation manual and a FIVE-YEAR electronics warranty.
