Condair Esco

2.4 Function
1
On the inlet side, the steam humidification systems Condair Esco DR 73 and
DL 40 are connected to the live steam supply. The steam on hand, when
the ceramic rotary-disk control valve is closed, is continuously drained by
means of the primary condensate drain (spheric float) float). Thus, the humidifier
is operable any time. The steam distributor, however, remains cold and
does not heat the air current; no energy is wasted.
With the ceramic rotary-disk control valve open, the steam passes through
the strainer into the water separator. As a result of the multiple steam deflection
in the water separator, the condensate, carried along, is reliably
eliminated and drained via primary condensate drain.
In the DR 73 type, the dried steam exits the water separator through the
ceramic rotary-disk control valve to flow via main distribution pipe into the
vertically arranged secondary pipes. The hot, dry steam is tapped at the
centre of the steam distribution pipes and discharged under pressure on
both sides, by means of special nozzles, at an angle to the air current.
Condensate, accumulating in the vertical pipes, slides along the inside of
the pipe down into the horizontally attached main distribution pipe (= collector).
This spaciously designed pipe is drained by way of an externally
mounted thermal secondary condensate drain.
In the DL 40 type, the steam is directly routed into the steam distribution
pipe, tapped at the centre of it and discharged under pressure, by means of
special nozzles, into or against the air current. Condensate, accumulating
along the inside of the pipe, is drained via condensate return line by way of
an externally mounted thermal secondary condensate drain.
Any condensate accumulating during system start-up is immediately drained
by the primary steam trap. The pre-dried steam is led via control valve into
the distribution system, where it is taken from the dry center of the pipe
and introduced uniformly into the volume flow by means of the differential
pressure. Thanks to this dependable system, there is no need for a start-up
protection and jacket heating.
Condensate-related backpressure is an impossibility in both lines of products
even in a pressureless state, because the steam distributor pipe is
drained via condensate return line with inherent down gradient.
