The FRS 660-5 OF-UL (Single Tank Unit) Fuel Recirculating System is UL 508A Listed and Green Clean Certified. It is designed to automatically circulate and clean fuel at 5 GPM for a single storage tank on a preprogrammed schedule.

The FRS 660-5-OF-UL utilizes RCI Technologies patented fuel purification technology, which contains no filters or moving parts. It is used as primary fuel purification and removes 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 to approximately 10 microns.

The control system is mounted on a panel which is placed in a customer supplied enclosure. The system consists of an RCI Universal Fuel Purifier, a continuous duty motor and fuel pump. The system is PLC controlled, with an Operator Interface Touch Panel that allows for system programming and alarm monitoring. Automatic controls are governed by a programmable 7 day, 24-hour real time clock with user definable start and run times. Relay alarm outputs include: pump failure, purifier high water level and system high pressure. Standard internal relays allow alarm status to be remotely monitored.

All electrical components and connections are housed within NEMA4X panels. FRS Systems are designed for use with all Class II or III combustible fuels having a flash point of 100ยบ F or higher. Multiple tank operations are available.
