4.4.2 Accessory details
Steam distribution pipes 81-... for indirect room humidification
The steam distribution pipes are selected on the basis of the duct width (for horizontal installation) or
the duct height (for vertical installation) and the capacity of the steam humidifier.
Important! Always select the longest possible steam distribution pipe (optimum humidification distance).

1) Only for units with a max. steam capacity of 10 kg/h
2) Only for units with a max. steam capacity of 30 kg/h
3) Special length available on request
Note: If the humidification distance (see chapter 5.3.1) has to be reduced for technical reasons, the
amount of steam per basic unit must be divided between two steam distribution pipes or the OptiSorp
steam distribution system must be used. If this is the case, contact your Defensor supplier.
Steam distribution pipe “Process” (accessory “Z...”)
The steam distribution pipe “Process” is used for direct humidification of material in manufacturing
processes (process humidification), or in ventilation ducts with a critical saturation distance (the
steam distribution pipe “Process” reduces the saturation distance by approximately 30%). The desired
length must be specified when ordering.
Please contact your Defensor distributor, they will assist you in customizing the steam distribution head
“Process”. Please have the following information readily available:
– steam quantity in kg/h
– dimensions of ventilation duct (width x height)
Important! The table for the determination of the humidification distance provided in chapter 5.3.1 does
not apply to the Process steam distribution pipe.
