3.3.1
Absorption distance "D"
Make sure that the absorption distance is met to let the air absorb the steam dispersed by the tubes. In this
absorption distance, the steam is still visible in the air stream in the form of fog. If any furniture is placed in this area,
condensate may occur. For this reason, it is imperative to consider this absorption distance when placing the
humidifiers.
3.3.2
How to calculate absorption distance « D »
In order to determine the absorption distance, the attached calculation table can be used:
▪
RH1 = relative humidity of air before humidification in %.
▪
RH2 = relative humidity of air after humidification in %.
▪
D mini = minimum absorption distance in meters (m).

This calculation table is to be used for temperatures between 20°C and 25°C (68°F to 77°F) (Maximum air speed 5m/s).
For calculated distances, contact your Devatec agent.
3.3.3
Minimum absorption distance
The steam dispersion pipes must be positioned after the minimum specified absorption distance. Please follow the
guidelines depending on the configuration of your air handling unit.
