  • Page 15 This calculation table is to be used for temperatures between 20°C and 25°C ( Maximum air speed 5m/s). For calculated distances, contact your Armstrong agent. 3.3.5 Minimal humidification 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.
  • Page 16 • A high humidity limit humidistat must be installed in the duct to stop the humidifier in case the level of humidity exceeds the preset value. • If the recommended distances cannot be met, please contact Armstrong or their authorized agent for an alternative solution.
