5. Humidification Output flow figure [m³/h] The maximum humidification output [kg/h] of Valve coefficient [m³/h] one steam injection unit depends upon the available steam pressure in barg. Example: Maximum humidification output can be more Desired humidification output: 110 kg/h than 770 kg/h (Type A) or 730 kg/h (Type C). Operating pressure, p = 2 barg Maximum operating pressure is pmax = 4,5 barg.

Position lances in the duct centre if possible. If the humidifier blows into a compact multi- zone unit then it should be installed directly in the air flow and as close as possible to the fan. The bifurcated pipe should never be installed less than one meter in front of the fan suction side.

When selecting the lance choose a size suffi- cient for the entire duct width or height. If the ducting is taller than it is wide, install the steam lance vertically. If this is not possible then a second lance must be installed in order to ensure an even steam distribution.
