Our Innovative Conditioned Steam Delivers Superior Humidification

Armstrong's improvements in steam humidification are fundamentally unique because they begin with the steam, not the humidifier. Unlike units that simply disperse steam, Armstrong’s direct-steam humidifiers work with the steam, guiding it through a carefully engineered, four-step conditioning process developed by our experts.


  • Slow and Strain—Steam is slowed down and strained to remove particulate matter.
  • Separate—Condensate is separated from the steam.
  • Dry—Steam enters a drying chamber; any remaining mist is re-evaporated.
  • Silence—The drying chamber is filled with stainless steel silencing material that absorbs the noise of escaping steam as it is generated at the control valve.

    • Series 1000 Stainless Steel Direct Steam Humidifiers  

      Series 1000 Stainless Steel Direct Steam Humidifiers

      Series 1000 Stainless Steel Direct Steam Humidifiers

      Armstrong offers Series 1000 steam-separator humidifiers for use in sensitive environments where pure demineralized, deionized or distilled water is used to generate clean steam. Wetted parts of the humidifier package are stainless steel, minimizing the carryover of impurities created by this highly corrosive water.

    • Unfired Steam Generators  

      Unfired Steam Generators

      Armstrong unfired steam generators (USGs) produce pressurized clean steam using boiler steam or high-temperature hot water as an energy source. USGs are designed to provide the correct balance of steaming area, coil size and control components to meet specified requirements. An over-pressure safety system closes both the feed-water and source steam valves, shutting the unit off. Typical uses include humidification, sterilization, pharmaceutical applications and food processing.
