Membrane Gas Sample Dryers

Outlet Flows from 2 to 10 lpm

 


Membrane Gas Dryer

The Sunsep drying process works by passing compressed air inside the hollow fiber membranes where the water vapor molecules permeate through the wall of the membrane leaving the oxygen and nitrogen molecules to exit the outlet as dry air. The permeated water vapor is then swept away by a small amount of dry air fed back over the outside of the membrane fibers through a purging valve or orifice.  With a countercurrent purge flow on the outside of the tubing, drying is continuous.

SWG Series and SWG-A01 Series

Sunsep membrane gas air dryers use exclusive flemion® tubing technology to dry gases to very low dew points.  The flemion tubing utilizes a hydrophilic polymer tubing that is very selective to water vapor only.  Water is removed in the vapor phase as a result of a chemical bonding between the water molecules and the polymer.
