Carbon Dioxide (CO2) Feed System

click to enlarge


The CO2 pH control system regulates the injection of Carbon Dioxide, a natural non-corrosive gas to replace hazardous liquid acid in chemical treatment of swimming pools, spas and water features. When dissolved in water, CO2 forms carbonic acid (H2CO3), a relatively mild acid which lowers the pH of the water while increasing total alkalinity.

Simple to install and operate, the CO2 pH control system is a safe, cost effective way to maintain precise pH balance while eliminating the hazards associated with storing and dispensing liquid acid.
