55-410 remote switchover
Chlorine dosing is one of the key processes on water and wastewater treatment plants. To ensure that this process is uninterrupted, Wallace & Tiernan® remote vacuum switchover units deliver continuous supply.
Switchover units provide unattended automatic switchover to a fresh gas
supply when the on-line supply is exhausted. The switchover is non-isolating
for complete gas withdrawal. This units are remote mounted and allow for vacuum
manifolding of multiple gas containers for high capacity feed rates up to 75 kg/hr
(4000 ppd) of chlorine. The switchover operates on vacuum and is installed in the
gas feed line between separate banks of vacuum regulating valves and the
control unit of a new or existing gas dosing systems.
