PERFORMANCE
MH-070 Performance Chart
A
MH™-Series Humidifiers are shell and tube
moisture exchangers that allow the transfer of
water vapor between a liquid water supply and a
flowing gas stream. Water is absorbed into the
walls of the Nafion
®
tube and transferred to the
dry gas stream. This transfer is driven by the
difference in partial pressures of water vapor on
the opposing sides.
