Like RCI’s regular FRS units, the basic-level system automatically cleans and circulates stored fuel on a pre-programmed schedule, it is PLC-controlled, and it has a key switch and a 24-hour, seven-day programmable clock.The system consists of an RCI fuel purifier, a continuous-duty motor and a fuel pump. The system has one general alarm relay contact, which is triggered by one of four alarms: pump failure, purifier high water level, system high pressure and fuel catch basin leak.This open-face unit can be wall-mounted or placed in an optional cabinet enclosure for ground mounting.The BL model has a smaller touchscreen than RCI’s other units; the PLC controls the alarms only; and the only options offered are power upgrades and the addition of a 3-micron filter. The BL series is available in three flow rates: 5 gpm (FRS 660-5-BL), 11 gpm (FRS 660-11-BL) and 25 gpm (FRS 660-25-BL). The BL model replaces the former EL (entry-level) FRS.
