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.

The Gas Pressure Reducing Valve is an independent, heavy-duty, spring loaded diaphragm valve, providing an automatically regulated output and a positive manual shut off.
The Series 50-185 Gas Pressure Reducing Valve (GPRV) is a spring-loaded, diaphragm operated valve used in gas-handling systems which reduces varying gas pressure to a desired regulated pressure and maintains within close limits.
Evoqua offers various automatic changeover modules to ensure an uninterrupted and unattended changeover to a fresh gas supply when the on-line supply is exhausted.
The Wallace and Tiernan® Evaporator Series 50-200 is an electrically heated, immersed tank-type heat exchanger. It is necessary wherever the required rate of gas withdrawal cannot be satisfied by direct connection to multiple containers
