Gas Feed Equipment and Control

Over 100 years ago, Charles F. Wallace and Martin F.Tiernan installed the first chlorinator in New York and since then 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. All of our gas feeders are based on the proven V-Notch™ flow control technology which provides a wide control range and very high repeatability.
