Unit in operation
Note!
Adjustments of flow rates should b e made slowly
in order to protect the system against s udden and
extreme variations of temperature and pressure.
During operation, check that:
• media temperatures and pressures are within the limits
stated on the name plate
• no leakages appe ar due to faulty tightening of the
connections.
Protection against c onnection loads
Make sure that the heat exchanger is fastened to avoid or
minimize connection loads during operation.
Protection against freezing
Bear in mind t
he risk of freezing at low temperatures. Plate
heat exchangers that are not in operation should be emptied
and blown dry whenever there is a risk of freezing.
Note!
To avoid damage due to freezing, the medium used
must include an anti-freeze agent when operating
conditions
are below 5 °C (41 °F) and/or when the
evaporating temperature is below 1 °C (34 °F).
Protection against clogging
Use a filter as protection against the pos sible o ccurrence
of foreign particles. If you ha ve any doubt concerning
the maximum particle size, please consult your Alfa Laval
Representative.
