Positioning the steam distributors in the duct
In positioning the steam distribution pipe DV41­.. and the steam nozzle
W21, the following dimensions should be observed:
Guidelines for dimensioning the ventilation ducts
– To facilitate the installation of the steam distribution pipes and for control
purposes, a sufficiently sized control opening should be planned.
– Within the range of the humidification distance, the ventilation duct
should be waterproofed.
– Air ducts passing through cold rooms should be insulated to prevent
the humidified air from condensing along the duct wall.
– Poor airflow conditions within the air duct (e.g. caused by obstacles,
tight bends, etc.) can lead to condensation of the humidified air.
– Steam distribution pipes must not be mounted to round ducts.
If you have questions relating to the dimensioning of ventilation ducts in
combination with steam humidifiers Nordmann ES4 4, contact your Nord-
