documentation for this product.
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.
– Low temperature ducts below 15°C, shallow ducts, or branch ducts might require the use of a field
supplied condensate drain pan below the steam distributor (see figure below).
– Air ducts passing through cold rooms should be insulated to prevent the humidified air from con
densing 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.
– Exercise extreme caution when installing in fiberglass or internally lined ducts. If necessary, remove
1015 cm of the lining where the steam is being introduced.
If you have questions relating to the dimensioning of ventilation ducts in combination with Condair steam
humidifiers, contact your Condair supplier.
