The ENL 100 serves to discharge con-
densate at places with a temporary
negative pressure (< 1 bar (abs) / 14
psi) and where backward suction of the
condensate must be prevented. During
negative pressure conditions, conden-
sate will not be discharged, this possibly
resulting in a backup. Subsequent to a
rise in pressure to approx. > 1.8 bar (abs)
(26 psi), condensate will be discharged
again and a possible backup reduced due
to a special function.
A centrifugal compressor which is able
to take up a no-load mode (vacuum) in
individual stages represents a typical field
of application.

Functionnement • Funcionamento
The condensate flows through the feed
line (1) into the ENL unit and accumulates
in the container (2). A capacitive sensor
(3) continuously registers the liquid level
and passes a signal to the electronic
control as soon as the container is filled.
The pilot valve (4) is activated immedi-
ately and the diaphragm (5) opens the
discharge pipe via the check valve (6) in
order to discharge the condensate.
In the case of negative pressure (< 1
bar (abs) / 14 psi) the check valve (6)
shuts and prevents the condensate from
flowing back.
The pressure difference at the check
valve is < 0.1 bar (1.45 psi).
When the ENL is empty, the discharge
pipe will be closed tight, in sufficient time
before any unnecessary losses in pres-
sure may arise.
