NRO SIMPLX SERIES SYSTEMS
2500 & 5000 Gallons per Day
Since 1954
NRO
Commercial Reverse Osmosis
System Features Include
• Axeon® XE1 Membranes
- The NRO 2540 Series features
Axeon® XE1 high performance
membrane elements that
operate at a low applied
pressure of only 100 psi.
The optional and economical CHIP Controller
removes the need for a low
pressure switch to control
the pump and a start delay
to prevent system cycling.
A switching power supply
operates on 96-264VAC,
automatically adjusting to
operating voltage. Voltage
at the supply terminals is the voltage for the
pump and valves. The CHIP controller allows
for tank level, system flushing, pre-treatment
lockout, & start-up delays.
The NRO SIMPLX
Series is competitively
rated for Commercial
or Light Industrial
applications requiring
• High Quality gloss
300psi FRP housings
• Easily Replaceable Motor
Mounting System - for ease of
field repairs
flow rates of 2500 and 5000 gallons per day
(GPD). NSF-grade high quality parts are used
to build this tough system.
The NRO SIMPLX Series is a Commercial
Reverse Osmosis System that doesn’t cut
corners and is engineered to deliver performance and quality. Performance without
compromise, this series includes all the
essential components necessary to
