Gas Humidification Solutions

Our humidifiers are powered by NafionTubing which selectively pulls water vapor into a gas stream. 

Common applications include humidifying calibration gasses, particle and aerosol streams, and air used in processes such as gas blending.

Water-to-Gas Humidifiers

Water-to-gas humidifiers are often used to humidfy:

  • Gases that don’t contain water soluble components
  • Air to be used in other processes, such as gas blending.

How they work:
Pump water through the purge ports, counter-current to your gas sample flowing through the Nafion™ tubing, and heat the water or the humidifier.

Then, Nafion™ tubing will selectively transfer water into the gas stream, achieving up to 99% relative humidity at the output.

Best for applications with flow rates up to 20 lpm.

Outputs up to 99% relative humidity

Input Gas:
– Flow rates up to 20 lpm
– Temperatures up to 80 °C
– Gas stream pressure up to 80 psig (5.5 barg)
-Differential pressure on Nafion™ tubing up to 10 psig (0.7 barg)

Water-to-gas humidification:
Requires water to be pumped into the purge port, running counter-current to the gas stream. 

Best for applications with flow rates up to 5000 lpm.

Outputs up to 99% relative humidity

Input Gas:
– Flow rates up to 15,000 lpm
– Temperatures up to 80 °C
– Gas stream pressure up to 45 psig (3 barg)
-Differential pressure on Nafion™ tubing  up to 5 psig (0.3 barg)

Water-to-gas humidification:
Requires water to be pumped into the purge port, running counter-current to the gas stream. 

Gas-to-Gas Humidifiers

Gas-to-gas humidifiers are often used to humidify:

  • Calibration gases
  • Particle streams or aerosol streams
  • Gases that contain water- soluble components

How they work:
Water vapor outside the Nafion™ tubing is selectively transferred into your gas stream flowing through the Nafion™ tubing.

For the BE Series, water vapor is pulled into the gas stream from the ambient environment.

For the MD and FC Series, pump humid gas through the purge ports, counter-current to your gas sample flowing through the Nafion™ tubing. Water vapor is pulled into the gas stream from the humid gas supplied to the purge port.

Humidify a gas using moisture in the ambient environment.

Output gas up to ambient relative humidity

Input Gas:
– Flow rates up to 2 lpm
– Temperatures up to 80 °C
– Pressures up to 90 psig (6 barg)

The BE draws in moisture from the ambient environment to humidify the gas stream.

Used to humidify a gas stream to a controlled relative humidity. Flow rates up to 4 lpm.

Output relative humidity up to 90% of humidifying gas

Input Gas:
– Flow rates up to 4 lpm
– Temperatures up to 80 °C
– Pressures up to 90 psig (6 barg)

Gas-to-gas humidification:
Requires humid gas pumped into the purge port, running counter-current to the gas stream. 

Used to humidify a gas stream to a controlled relative humidity. Flow rates up to 5000 lpm.

Output relative humidity up to 90% of  humidifying gas

Input Gas:
– Flow rates up to 5000 lpm
– Temperatures up to 80 °C
– Pressures up to 45 psig (3 barg)

Gas-to-gas humidification:
Requires humid gas pumped into the purge port, running counter-current to the gas stream.
