UL-142 Secondary Containment Automatic Day Tanks

Description

Secondary Containment Automatic Day Tanks are designed to automatically maintain a full day’s supply of fuel for the generator set.

The basic Secondary Containment Automatic Day Tank comes furnished with a pump, motor, “press to test” switch, and a “pump running” light. This system allows the tank to automatically pump fuel, from the main storage tank, into the Day Tank. Originally the tank was sized to provide a 24 hour source of fuel for the generator set, however, through the years, local codes and specifying engineers have modified the original definition. Today an Secondary Containment Automatic Day Tank is any tank that maintains a supply of fuel through the use of a locally mounted pump, motor and internal float switches.

Engine & Compressor Accessories has developed over the years a simple yet effective pump control circuit. Our flexible system allows us to customize the control circuitry to your specifications, while keeping the cost in line with other non-flexible printed circuit board systems. Our system consists of hard wired, socketed relays in conjunction with internal float switches and lights mounted on a panel to display and control many different functions.
