Gas Feed Systems

All-vacuum operated gas feed equipment & solutions for simple & reliable disinfection dosing, control & safety management

Chlorine gas has been the predominant chemical for the disinfection of water since our founders Charles F. Wallace and Martin F. Tiernan installed the first chlorinator in New York over 100 years ago. Using a remote vacuum-operated gas feeder, a chlorine solution is prepared on-site by dosing the chlorine gas into the process water. Benefits of the system include: the most economic disinfectant available supplied as gaseous or liquid chlorine supplied in cylinders or ton containers, safe all-vacuum dosing operation using accurate and reliable V-Notch™ flow control technology, manual and automatic dosing control options, automatic detection and shut-down in the event of accidental gas release, and complete design and system supply of all gas feed and handling equipment and safety management accessories.
