DC400 Dispensing Cutoff SystemThe 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. |
Advantages
- Automatically stops fuel from dispensing in the event of liquid detection.
- Easily installed in either turbine or dispenser sumps.
- Ideal for retrofit applications as system connects to existing turbine or dispenser wiring, eliminating the need to pull new wires or break concrete.
Installation
Simply mount the 404-4 Controller inside any containment sump and connect it to the existing turbine or dispenser wiring. Connect the liquid sensor using the supplied water tight splice kit. Place it in the bottom of the containment sump.
Application
Containment sump liquid detection resulting in dispensing cutoff.
