DC400 DISPENSING
CUTOFF SYSTEM
The DC400 dispensing cutoff system is a stand-alone, solid
state two-part system which includes a controller and sensor,
designed to automatically shut down product flow if liquid
is detected inside containment spaces. Ideal for retrofit
applications, the DC400 allows for easy compliance with
new and evolving regulations, without the added expenses
of shutting down your site to break concrete for new conduit
and wiring installation. The DC400 can be mounted inside
any turbine sump to provide complete pump shut down or
mounted directly into dispenser sumps, allowing only the
affected dispenser to be shut down as liquid is detected.
