International brand dossier
Codeline Pressure Vessels
Pentair is a broad water equipment group whose water-treatment brands include control valves, softening components, filter housings and cartridges, pumps, membrane housings, and X-Flow membrane modules.
Its influence comes from installed-base breadth: many residential, commercial, industrial, and packaged water systems are designed around Pentair components, so selection often depends on service parts, controls, and compatibility as much as on the individual product rating.
Codeline Pressure Vessels's position in RO/NF membranes and related equipment is defined by product families such as 4" CodeLine Membrane Housings, 8" CodeLine Membrane Housings, Ecoline series and Accessories.The portfolio is best understood inside brackish water, seawater desalination, ultrapure water, process separation, reuse, degassing, and membrane system packaging, where engineers compare the technology route, family boundaries, and duty fit before narrowing to individual models.Representative series on this page include CodeLine 40 E, CodeLine 40 S and 40E30.

How to choose Codeline Pressure vessel brands
This section answers two questions: which main product families Codeline offers, and which parameters to compare before choosing a specific model.
Step 1: Choose a product family by application
The main families shown on this page are 4" CodeLine Membrane Housings, 8" CodeLine Membrane Housings, Ecoline series, and Accessories. Start with the treatment objective, equipment format, and operating duty, then use the model index below to compare exact specifications.
Step 2: Confirm the model by key parameters
After choosing a product family, compare feed salinity, target salt rejection, permeate flow, operating pressure, fouling tendency, and element size and connection. Replacement projects should also verify installation or loading conditions, interfaces, and compatibility with the existing system; new projects should consider operating practice, maintenance, and spare-parts or consumables availability.
