GENERAL
Attainment of good steam distribution and therefore the desired humidity level in any
environment depends on two key factors: the quantity of steam introduced into that
environment and how it is distributed.
If, in fact, the steam is introduced into an environment in a heterogeneous manner there will be
zones of excessive humidity and zones that are too dry: this can lead to excessive condensation and
problems in controlling steam production due to the triggering of a “pendulum” feedback effect.
It is advisable to introduce steam by inserting a PEGO distribution lance in the air duct or in front of
a ventilation unit (where the steam is introduced directly into a room and not through a duct).
EXAMPLE OF IN-DUCT STEAM DISTRIBUTION
The PEGO distribution lance must be
inserted perpendicularly to the direction of
air flow in the duct.
To optimise distribution efficiency the lance
must cover as much of the effective air flow
width as possible
