Loosen all tie bars in 3 mm increments to “X
+ 5%”, and then remove only the 2 top and
the 2 bottom tie bars in the positions shown
in the picture.
Loosen rest off the tie bars in increments of
up to 6 mm to “X + 10%”.
For large or tall units ( where the distance
between tie bars labelled 1 and 3, exceeds
1200 mm, 4 ft), remove all tie bars except 1
to 6. Loosen tie bars 1 to 6, moving in that
order, in increments of max. 25mm until all
tie bars become loose.
For smaller units, (distance between bars 1
and 3 is less than 1200 mm, 4 ft) remove all
tie bars except 1 to 4. Loosen tie bars 1 to 4,
moving in that order, in increments of max.
25mm until all tie bars become loose.
When using hydraulic tightening units,
ensure that each tie bar is loosened equally
during opening.
When the plate pack is fully released and the
tie bars removed, the heat exchanger can be
opened by pushing the follower back against
the end support.
Ì! For large units, block the follower into
position, for example by tying it to the end
support, to provide extra safety against
accidental rolling of the follower during
maintenance.
Separate the plate pack carefully to avoid
damaging the gaskets or the plates.
