X2 – SERIES REVERSE OSMOSIS (RO) SYSTEM

The AXEON X2 – Series is designed to be a cost–effective reverse osmosis (RO) system for light industrial, 8” membrane applications with a capacity of 30 gallons per minute (GPM) or 43,200 gallons per day (GPD).

The X2 – Series system is a mid-range model designed for OEMs and distributors servicing the water treatment industry. Certain models come with options from a select list of add–ons and upgrades, although some of the options are not included on this model.

The X2 – Series systems come pre–assembled and pre–wired for ease of installation and servicing. The simple design of the X2 – Series systems make them easy to use, cost effective and reliable water purification systems.

The X2 – Series systems are designed to treat brackish feedwater sources drawn from well water with total dissolved solids (TDS) levels of 7,000 ppm. The X2 – Series are built with SS Schedule 40 piping on the high pressure side. The equipment and components are recommended not to exceed the maximum operating pressure of 400 psi.
