Installation rules
The following basic rules should always be obser-
ved for installation of the BEKOMAT:
1.
The condensate must be fed into the BEKOMAT with
a continuous downward slope (head) and through a
preferably short condensate inlet line.
Recommended minimum pipe diameter:
BEKOMAT 3
G ¾" (Inner diameter > 18 mm)
BEKOMAT 6
G 1" bzw. ¾"
(Inner diameter > 18 mm bzw. > 22 mm)
2.
The continuous slope serves to en-sure the unimpeded
inflow of conden-sate into the BEKOMAT, whilst allow-
ing the return of air from the container. The device can
only fill with conden-sate, when the inflowing volume of
condensate is balanced by a corres-ponding volume of
outflowing air.
3.
If for technical reasons only the lower “IN” connection
of the BEKOMAT can be used for condensate inflow,
then the air exchange described under 2. is only
assured in conjunction with a balance air pipe connec-
ted at one of the upper “IN” connections. There must be
the same pressure prevailing at the entrance and exit
points of the balance air pipe. The recommended
minimum pipe diameter amounts to ¼" (or G ½" in the
case of BEKOMAT 6 variants). The balance air pipe
connection at the vessel to be drained (exit) must lie
above the max. possible condensate level.
BEKOMAT 3 variants:
Equally, installation of such a balance air pipe is
always required, when the condensate flow rate ex-
ceeds 120 l/h, which may generally be the case with
a compressor performance above 40 m¦/min during
summer temperatures.
BEKOMAT 6
BEKOMAT 6 variants must always be fitted with a
flexible air pipe (min. ½") as described above under item
3. This type of installation is explained further in the
following examples of installation and associated dra-
wings.
4
. The condensate discharge pipe must fixed to the wall
with a rising slope of no more than 5 m length. Here,
it should be taken into account that the minimum
operating pressure required (see page 11) will increase
by about 0.1 bar per metre of level difference.
5.
It is only permissible to join several condensate di-
scharge pipes to one collecting pipe, if all the relevant
discharge pipes are subject to the same pressure.
With different pressures, e.g., in the case of multi-
stage compressors, there must be a separate collec-
ting pipe for each pressure level. The collecting pipe
must measure at least G 1", and there should be an
atmospheric pressure of eg = 0 bar at the pipe exit
point. The collecting pipe must never be closed by a
valve or similar fitting.
6.
Do not use any conical pipe joints, since this may
damage the threaded connections.
CAUTION
If above notes are disregarded during installation, proper
functioning of the BEKOMAT can no longer be guaran-
teed. The same applies with respect to the following
examples of installation.
Examples of installation
IMPORTANT
During installation and operation the “Installations rules”
and the “Examples of installation” must be observed at all
times. The following examples of installation represent
merely a selection of the installation options possible in
practice.
In our experience most cases of malfunctioning of the
BEKOMAT are due to incorrect installation.
It should therefore be realised that installation errors can
cost a great deal in terms of time and money.
If your particular application requirements are not conside-
red in the following examples or if there are still further
points you would like to clarify, please contact your
supplier.
