Humidifier Nafion, 7000 tubes 0.04", 7" length, PP shell/fittings

FC™-Series humidifier

Perma Pure FC™-Series humidifiers use an exclusive Nafion membrane tubing to continuously humidify gas streams. These humidifiers operate over a wide range of flowrates and can use either liquid water or a humid gas stream as a source of humidity. Water-to-gas humidifiers have liquid water on one side of the tube wall and a dry gas on the other. This arrangement offers the greatest amount of humidification; however, the reaction of the water molecules moving through the tubing wall absorbs heat. To counter this cooling effect, the inlet water must be heated. Hot, circulated deionized water should be used to optimize performance. Gas-to-gas humidifiers use counter-flowing wet and dry gas streams to move heat and moisture from one stream to the other. These units are energy efficient, as they do not require any additional power or heat. When gas passes inside the Nafion tubing, water is absorbed by and moves through the walls of the tubing. The movement of water is driven by the humidity gradient between the inside and outside of the tubing. Since only water molecules move through the tubing walls, liquid water is prevented from becoming entrained in the gas stream.
