1. Introduction
Dry gas flows through one side of the device while the other side is filled with water. The water molecules selectively transport from water into gas phase, driven by partial pressure difference. In addition to humidification, the gas temperature can be increased by circulating hot water.
2. Performance Attributes
-
No gas/liquid crossover: no gas loss to water, no water droplet in gas
-
The membrane bocks transport of any bacteria, virus and inorganic/organic
impurities from water into gas.
-
The zeolite/porous Nickel alloy sheet is bio-fouling resistant
-
The device made of polycarbonate glass for low-pressure and low-temperature applications
-
The device made of stainless steel for higher pressures and/or temperatures
-
Compact and easy maintenance
3. Application Example
Dry air heating and humidification (membrane area 40 cm2)
