Thank you for choosing a PEGO steam distributor for immersed electrodes humidifiers
EASYSTEAM.
The complete reading of this manual will allow you to perform a correct installation.
We therefore recommend that you keep this manual.
GENERALITY
A good distribution of steam, to obtain the desired level of humidity in any environment,
is linked to two main variables: the amount of steam introduced into the environment and
its distribution.
In fact, when the steam is introduced into an environment in a non-homogeneous way, it tends to
create saturated zones and zones deficient in humidity, causing a phenomenon of excessive
condensation and the difficult control of the production of steam and triggering a "pendulum"
effect. It is advisable to introduce the steam with a PEGO steam distributor, inserting it into the air
duct or in front of a fan unit where you want to put the steam directly in an environment without an
air duct.
MAIN INSTALLATION WARNINGS
1. Use only PEGO HUMIDIFIERS steam tube or other tube with certification that guarantees its
use in the presence of high temperatures without internal vulcanization processes and release
of harmful substances.
2. The steam tube must be of a suitable diameter and must be firmly fixed to the steam
distributor with a hose clamp.
3. Do not make bottlenecks, siphons or lengths greater than 5 meters.
4. Do not make sharp bends or at 90 °. The minimum bending radius (at 20 ° C) is 115mm for
the UMITUBVAP25M tube and is 180mm for the UMITUBVAP40M tube.
5. If rigid pipes are used, use only copper or stainless steel pipes and connect the rigid steam line
to the steam distributor, using a small portion of steam tube, fixed with the appropriate
clamps.
6. The provisions of points 2, 3 and 4 also apply to rigid pipes.
7. To facilitate the installation of steam distributors and for control reasons, an inspection hole of
sufficient size must be provided inside the air duct.
8. Within the humidification distance, the ventilation duct should be watertight.
9. The air ducts that pass through cold environments must be insulated so as to avoid
condensation of the humidified air on the walls of the duct.
10. Unfavorable fluid dynamic conditions inside the air duct (eg. due to obstacles, tight bending
radii, etc.) can cause condensation of the humidified air.
11. For any questions, please contact the Pego service center, listed on the back of this manual.

EXAMPLE OF DISTRIBUTION IN AIR DUCT
The PEGO steam distributor must be inserted
transversally to the air flow in the duct and with the
holes facing upwards.
The steam distributor must be positioned horizontally,
tilted so that the tip is slightly higher than the base;
this to allow an efficient recovery of any condensation.
To improve the efficiency of the distribution, the
steam distributor must cover the width of the airflow
as much as possible.
NB: The maximum airflow pressure in the air duct
must not exceed 1,200Pa (fig. 1).

EXAMPLE OF DISTRIBUTION IN AMBIENT
The PEGO steam distributor must be positioned
transversely in front of the air flow of a fan unit and
with the holes facing upwards.
The steam distributor must be positioned
horizontally, tilted so that the tip is slightly higher
than the base; this to allow an efficient recovery of
any condensation.
To improve the efficiency of the distribution, the
steam distributor must cover the width of the airflow
as much as possible (fig. 2).

EXAMPLE OF DISTRIBUTION IN TURKISH BATH
The steam diffusion nozzle must be positioned at the bottom and in such a way as not to direct the
steam jet directly onto the users of the Turkish bath.

CONDENSATION RECOVERY
1. Regardless of the type of application, a certain
amount of condensation forms inside the steam
distributor.
This condensation must be drained in order not to
obstruct the steam flow. If the steam distributor is
positioned at a point higher than the humidifier and
the steam tube does not generate siphons, the
condensate recovery tube may not be installed (eg.
fig. 3).
Fig. 3
2. If the steam distributor is positioned at a point higher than the humidifier and the steam tube
generates a siphon (e.g. Fig. 4), the condensate recovery tube must be installed, directly
discharging in the appropriate cylinder sleeve of the humidifier (Fig. 5) or in a water collection
well. Condensate recovery is performed by connecting the PEGO UMITUBODN10 tube,
specific for this type of application, to the 10mm diameter sleeve of the steam distributor. In the
path of the condensate recovery tube, from the steam ditributor to the humidifier or from the
steam ditributor to the well, it is necessary to perform a siphon with a complete turn with a
minimum diameter of 200mm; the siphon must also be filled with water before installation.
This will prevent the steam outlet from the condensate recovery tube (fig. 4).
Fig.4 Fig. 5
3. If the steam distributor is positioned lower than the humidifier, as generally happens in
installations with OEM series humidifiers, it is essential to perform the condensate recovery by
discharging into a water collection well.
