The FRS 660-40 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 25 GPM for a single storage tank on a preprogrammed schedule without the use of filter elements.

The FRS 660-40 UL utilizes RCI Technologies patented fuel purification technology, which contains no filters or moving parts. It is used as primary fuel purification and removes 99.9% 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 housed in a NEMA 4, Touch key lockable enclosure. consists of RCI Universal Fuel Purifier, continuous duty motor pump. The is PLC controlled, an Operator Interface Panel that allows for programming monitoring. Automatic controls are governed by a programmable 7 day, 24-hour real time clock with user definable start run times. Four (4) relay outputs include: pump failure, purifier water level, system high pressure and fuel catch basin leak. 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 100° F or higher. Multiple tank operations are available.
