This revolutionary design combines important advantages.

modular design

fewer manifolds / couplings needed
flow control for each housing
Feed-, Brine, Permeate Water sampling directly at the elements
measuring of pressure/differential pressure at membrane surfaces

We keep the advantages of our RO/SP series
the in-liner : protecting the fiberglass shell against medium attack
the self sealing endplate/head system

In January 2016 we introduced an extra service to our customers
we provide chemical alteration tests on the materials used for the Xtype membrane housings.
