Operation Plate Heat Exchanger (PHE)
Before each operation make sure that the plate pack is clamped to the correct compression dimension "a" and
that the plate heat exchanger is anchored to the ground.
Additionally make sure that all connection pipes are screwed tight and that the permitted values for pressure
and temperature given on the fabrication label are not exceeded.
The correct compression dimension can be found on the supplied dimension sheet or fabrication label. Prevent
pressure surges when starting up the PHE or after brief stoppages.
If an operating PHE is shut down, it should be cooled down and cleaned afterwards. The plate pack should be
loosened to "a" + 10%, starting from the current "a" dimension. This action reduces the pressure on the
gaskets
