5.4 Steam distribution in an AHU or duct
The humidifier must be connected to a stainless steel steam distributor with a fixing flange in engineering plastic in order to
distribute steam in the ventilation system.
The steam distributor must be installed:
• Vertically;
• At least one metre from the top of the duct;
• At the bottom of the duct (so the steam can mix properly with the air);
•
Higherthanthehumidifieroutlet;
•
Ascloseaspossibletothehumidifier(topreventreducedefficiency).

The insulated pipe fitting between the humidifier and the distributor must not be fitted with siphons and must always slope
down towards the humidifier to ensure the condensate runs freely in the machine.
WARNING
MATERIAL DETERIORATION
• The special steam piping must be fixed to the boiler and stainless steel ramp with stainless steel ties.
• Only use material suitable for the intended use.
