Wallace & Tiernan® Chlorine Gas Feed Systems


About 100 years ago, Charles F. Wallace and Martin F. Tiernan installed the first chlorinator in New York, and since, chlorine gas has been the predominant chemical for the disinfection of water.

The most economic disinfectant is available as gaseous or liquid chlorine supplied in cylinders or ton containers. Using a remote vacuum operated gas feeder, a chlorine solution is prepared on site from chlorine gas and water. This solution is used as a disinfectant.

Our chlorinators operate using the all-vacuum principle, which means that there is a vacuum from the cylinder up to the injector. All of the gas feeders are based on the worldwide proven V-notch flow control technology which provides a wide control range and very high repeatability. Control of the gas feed rate can be adjusted manually or automatically via an electric positioner.
