Diesel fuel recirculating system.
RCI Technologies has introduced the FRS 660-11-DPU-UL, the newest addition to the company's line of diesel fuel purifiers and fuel recirculating systems. The DPU, or duplex pump unit, is designed to automatically circulate and clean the fuel in fuel storage tanks on a pre-programmed schedule. The DPU features two fuel pumps, which operate alternately to circulate the fuel through the system. The FRS is used for primary fuel purification and is designed to remove 100% of all free water, including emulsified water, and up to 98% of the normal solid or particulate contaminates found in fuel, including sludge and algae. All FRS units employ RCrs patented filterless technology, using no filters or moving parts. The units are UL-listed and Green Clean certified, and the control system is housed in a weatherproof, NEMA 4, key-lockable cabinet. The system is equipped with alarms to alert the user in the event of pump failure, purifier high water level, system high pressure and fuel catch basin leak.
