The linear distributors are mounted (see Fig. 8.3.3):
by making a series of holes in the wall of the duct, as per the
drilling template indicated in Figs.: 8.3.1 or 8.3.2;
inserting the distributor with the steam outlet holes facing
upwards;
fastening the flange of the distributor using 3 screws.
To allow the condensation to return through the drain
connection (see Installing the condensation return tubing),
mount the distributor at a slight angle (at least 2°-3°) with the
inlet connection nearer than the closed end, which, for this
reason, must be adequately supported.
8.4 Concentrated jet steam distribution
For special applications (e.g. steam baths, technological machinery) a plastic OEM concentrated jet distributor is available,
with holes (12 or 22mm) or without, allowing the user to make these according to requirements (see Fig. 8.4.1).
The OEM distributors can be fitted, horizontally or vertically with the hole facing upwards, onto a support with the same holes
as per the drilling template for the aluminium linear distributor (see Fig. 8.3.1).

8.5 Positioning linear distributors in the air duct

Depending on the dimensions of the air duct, the distributors must be as long as possible and placed away from curves,
branches, changes in cross-section, grids, filters, fans.
The minimum recommended distance between the steam distributor and the nearest obstacle is around 1 1.5 metres, yet this
strongly depends on the operating conditions; it in fact increases as a result of:
the increase in speed of the air in the duct;
the increase in relative humidity of the air before and, above all, after humidification;
the decrease in turbulence.
The distance can be shortened using a series of distributors in parallel.
