Heat transfer problems
The heat transfer capacity is dropping.
Action
1.Measure temperatures at inlets and outlets. Also measure
fl ow rates on both media, if possible. On at least one of
the media, both temperatures and the fl ow rate must be
measured.
Check to see if the transferred amount of heat energy
corresponds to the speci
fi cations.
If great precision is important, it will be necessary to use
laboratory thermometers with an accuracy of 0.1 °C, and also
to use the best equipment available for
fl ow measurement.
Has the heat transfer capacity of the unit dropped below
speci
fi ed values?
Correction
YES
Clean the heat transfer surface. Use the
Cleaning-In-Place (CIP) system.
NO
