AUTOMATIC CHANGEOVER SYSTEM FOR LIQUID Cl2, SO2, OR NH3 SUPPLIES

  APPLICATIONS
For use on ton containers, tank cars, and
other large gas or liquid-chlorine supplies,
this system gives automatic changeover
to a fresh supply when the on-line supply
runs out. The system’s two motorized ball
valves are monitored and controlled from
a single panel. They are ideal ahead of
chlorinator-evaporator combinations; one
system can supply up to 10 manifolded
evaporators. Can be used for liquid
ammonia or sulfur dioxide.
