Capital Controls® Gas Feed systems & scrubbers

Gas feed and scrubbing solutions built for dependable disinfection and plant safety.

Capital Controls® systems set the global standard for safe gas handling in water disinfection equipment and systems, from municipal water treatment solutions to industrial processes.

As the pioneer of the all-vacuum gas feed system, Capital Controls introduced a safety-first design that remains the benchmark today.

The portfolio includes vacuum and pressure gas feeders, chlorine disinfection controllers for water treatment, ejectors, vaporizers, analyzers and scrubber systems for water treatment that help mitigate hazardous gas releases.

With six decades of innovation, thousands of global installations and deep application expertise, Capital Controls delivers safe operation, strong reliability and total lifecycle support.

Vacuum operation adds a built-in safety advantage by stopping gas flow automatically if a line is compromised, while analyzers and chlorine disinfection controllers for water treatment keep dosing stable as conditions change.

For hazardous-gas mitigation, Capital Controls® provides industrial gas scrubber systems and emergency gas scrubber systems that contain and neutralize releases using wet or dry scrubbing designs sized for municipal and industrial facilities.

Together, these systems deliver safe operation, reliable disinfection and lower chlorination operation and maintenance costs across a range of municipal water treatment solutions and industrial applications.
