Unit in operation
Note!
Adjustments of fl ow 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
• no leakages appear due to faulty tightening of the
connections.
Protection against connection loads
Make sure that the heat exchanger is fastened to avoid or
minimize connection loads during operation.
Protection against freezing
Bear in mind the 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 fi lter as protection against the possible occurrence
of foreign particles. If you have any doubt concerning
the maximum particle size, please consult your Alfa Laval
Representative.
