Benchtop 0-10 lpm Bubble Humidifier


  • The bubble humidifier saturates the gas stream to 100% RH at the specified dewpoint.
  • Available with a variable gas bypass option to provide gas humidification with relative humidity
    from 0% to 100% RH
  • Headspace heaters prevent condensation to provide an exceptionally wide dynamic range of gas
    flows from 0 to 10 slpm
  • For your safety, we include redundant system protection on each humidification channel:
    over-temperature cutoff, over-pressure cutoff, and a rupture disk for added safety!
  • Humidifier can be operated as a stand-alone unit or controlled with Fideris FCPower software
  • The humidifier can be combined with additional Fideris components as well as third-party equipment
    to achieve a fully-integrated, fully-automated, customized system
  • Independent dew point temperature control of two humidification channels
  • Independent headspace temperature control of the two humidification channels, which assures full
    humidification of small gas flows (those less than 2 slpm)
  • Independent temperature control of optional heated gas transfer lines
  • Front panel display of temperatures
  • Up to 1800 Watts per channel heating capacity
  • Automatic water refill
  • Connect directly to house deionized water supply or order with internal water pressurization system
  • Water handling system designed for use with deionized water
  • System designed for reactant gas pressures up to 50 psig
  • Designed for ease of diagnostics and maintenance
  • Integrated hardwired Run/Standby signal
  • Also available in a 100 slpm model
