Walz KF-18/2B & KF-24/6B Cold Traps: Humidity Control in Gas Stream
Cold traps control the humidity in a gas stream. For this purpose, the gas stream is directed through the cold trap and cooled down to the set temperature. If the dewpoint of the inflowing gas is above the set temperature value, the excessive water vapor condenses and the outstreaming gas has a defined dewpoint, corresponding to the set temperature value. If required, the gas may be humidified prior to streaming into the cold trap.
The cooling inside the cold trap is performed with Peltier coolers regulated by a temperature controller. The condensate accumulates in a hose and may be let off from time to time.
