4. STEAM DISTRIBUTION
To achieve optimal humidifi er effi ciency, the steam produced must be introduced into the room uni-

formly, in order to prevent the spraying of drops and notable condensation. This is best achieved using

steam blowers or linear distributors. The right steam distributor must be chosen according to the place
where the steam is to be introduced.
4.1 Steam distribution in ducts - linear distributors
For steam distribution into air ducts, the steam distributor must be sized according to the output of the

humidifi er and the cross-section of the ducting. Figure 4.a provides the dimensions of the CAREL linear

N.B.: if the duct is not wide enough for the distributor, two shorter distributors can be used (numbers in
Tab. 4.a
brackets), by branching off the steam hose.
Assembly of the linear distributors (see Fig. 4.a):
• make a series of holes in the wall of the duct according to the drilling template indicated in Fig. 4.a;
• insert the distributor with the steam holes facing upwards;
• fasten the fl ange of the distributor using 4 screws.
To allow the return of condensate using the drain connection (see Installation of the condensate drain
pipe), mount the distributor (Fig. 4.a) with the inlet connection closer than the closed end, which, for this
reason, must be adequately supported (the support surface already has the right slope).

4.2 Positioning the linear distributors in the air ducts
As allowed by the dimensions of the air duct, the distributor must be as long as possible and located
away from curves, branches, changes in cross-section, grills, fi lters and fans.
The minimum recommended distance between the steam distributor and the nearest obstacle is around
1-1.5 metres, yet this greatly depends on the operating conditions; this distance it in fact increases with:
• an increase in the air speed in the duct;
• an increase in the relative humidity of the air before and, above all, after humidifi cation;
• a decrease in turbulence.
Follow the indications and the distances between the distributor and the walls of the ducting and/or
between two distributors, as indicated in the fi gures below (distances in mm).
