Excalibur SFLC Series

The Excalibur Water Systems SFLC Series Reverse Osmosis is an ideal solution for light commercial reverse osmosis units offering product permeate flow rate ranges from 1-3 gallons per minute with three standard turn key product engineering models.

The SFLC economical controller provides relays for the RO pump, inlet solenoid valve, and membrane flush solenoid valve. The dry contact switch inputs monitor storage tank level, low and high pressure switch signal, and system lockout for pre-treatment backwash or regeneration for on/off operation. All inputs and outputs are controlled with time delays for proper operation.

Low pressure standard operation utilizing Filmtec XLE membranes, stainless steel membrane housings, blue white flow meters, inlet solenoid valve, pressure pump with recirculation 75% recovery constructed on a heavy duty powder coated blue steel frame.
