How do I find the correct unit?

  • Step 1: Determine your HVAC application area.
  • Step 2: What humidity would you like to get at what room temperature?
  • Step 3: Calculate your humidification demand with our calculation tool.
  • Step 4: What water quality is available?
  • Step 5: What is the unit loading likely to be (operating period in hours per day)?
  • Step 6: Would you like to humidify or to cool?

Firstly the application area, which is associated with a required air humidity, plays a decisive role. You can find more information about this on our HVAC application area pages.

The available water quality determines which unit technology is possible. Electrode steam humidifiers require electrically conducting water and are therefore well suited to tap water.

When used with fully demineralised water, heater element steam humidifiers require little to no maintenance. Where this is available, this unit type is particularly suitable. However, they can also be used with tap water.

Atomisers moisten and cool the air adiabatically. A fine spray cloud is produced, which is very quickly absorbed into the air, cooling the air adiabatically. This ensures hygienic humidification with minimum energy consumption and maximum efficiency.

Our units can be found on the HVAC product line pages.
The required steam output (kg/h) can be calculated from the room conditions (or the size of the location, room size, air exchange, insulation, etc.) and the required humidity. Our design program is useful in this respect.
Moreover, the questions as to whether a stand-alone or integrated unit are required and the loading requirements (heavy, continuous, medium or intermittent) will be subject to the design prefereance to define which particular product line is suitable for you.
