Maintenance
Closing
Follow the instructions below to ensure that the heat exchanger will be properly closed.
For bolt identification, refer to “Bolt configuration” on page 20.
Step 1
Check that all the sealing surfaces are clean.
Step 2
Brush the threads of the bolts clean, using a steel wire brush or
the Alfa Laval thread cleaner. Lubricate the threads with a thin
layer of grease, e.g. Gleitmo 800 or its equivalent.
Step 3
Attach the gaskets to the plates or check that all gaskets
are properly attached. Check that all gaskets are correctly
positioned in the grooves.
Note!
If the gasket is wrongly positioned, it will show by the
fact that it rises out of the gasket groove or that it is
positioned outside the groove.
Step 4
If the plates have been removed, insert them in alternate
directions and with the gaskets turned towards the frame plate
or pressure plate as specified on the plate hanging list. Use
the marked line that was made when the heat exchanger was
opened, refer to Step 7 in “Opening” on page 20.
Step 5
If the plate pack has been marked on the outside, check this
(see Step 7 in “Opening” on page 20).
If the plates are correctly assembled (A/B/A/B etc.), the edges
form a “honeycomb” pattern, see picture.
