5.2 Unit in operation
Adjustments of flow rates should be made slowly in order to protect the
system against sudden and extreme variations of temperature and pressure.
During operation, check that media temperatures and pressures are within the
limits stated on the name plate and the PHE drawing.
WARNING
In case of failures that endanger safety operation, turn off the flows to the
heat exchanger in order to decrease the pressure.
5.3 Shut-down
NOTE
If several pumps are included in the system, make sure you know which one should be stopped
first.
1
Slowly close the valve controlling the flow
rate of the pump you are about to stop.
2
When the valve is closed, stop the pump.
3
Repeat step 1 on page 27 and step 2 on
page 27 for the other side for the second
media. Continue with both sides of each
section.
4
If the heat exchanger is shut down for several
days or longer, it should be drained. Draining
should also be done if the process is shut
down and the ambient temperature is below
the freezing temperature of the media.
Depending on the media processed, it is also
recommended to rinse and dry the heat
exchanger plates and connections.
NOTE
Avoid vacuum in the heat exchanger by
opening vent valves.
