RO pressure vessels – Reverse osmosis pressure vessel
Our reverse osmosis RO pressure vessels in composite are the best product in this segment. They combine a really great look with an extreme ease of installation, requiring no high-pressure hose to interconnect each other in multi-membrane systems, thanks to the side ports machined in the heads.
Compact movable unit made by high performance composite material, very light and strong. This kind of RO pressure vessel is easy to handle and fit aboard. Designed for a continuous long-term use and for a maximum working pressure of 70 bars. Great, clean and elegant design.
In this video 
we show how to insert the reverse osmosis membranes into the RO pressure vessels. It is a simple and easy operation that does not require any kind of special tool.
These RO pressure vessels can accommodate any standard 2.5”×21” and 2.5”×40” seawater reverse osmosis membranes.
The end plugs are are machined with a CNC milling from a bar of AISI 316L stainless steel for the maximum in corrosion resistance.
The tie bars are as well made of stainless steel, covered with a black PVC duct.
The pressure pipe is coated with a special protective film (guaranteed up to 10 years outdoor durability) and can be ordered in blue (default), silver grey or black.
A pair of stainless steel angle brackets can be supplied separately as optional.
• End-cap inlet and outlet in AISI 316L Stainless Steel
• Double O-ring on the end-caps
• Models from 1 to 4 membranes sizes 2540 and 2521
• Each RO pressure vessel is factory tested at 1,5 times max operating pressure
• Feed/concentrate connections 1/4″ NPT, permeate connections 1/4″ NPT
The RO Pressure Vessel can be coupled to high pressure water pump units with different flow rates, thereby achieving several production rates of freshwater.
