Alfa Laval Compabloc Plate Heat Exchanger CP30

Dismantling Procedure for Panels

Progressively loosen the nuts one girder after the other

Loosen bottom nuts one panel after the other

Do not unscrew stud bolts or nuts for girder assembly

Remove panels starting with the highest weight

Use welded or screwed lifting lugs to lift panels safely

Clean gasket seating surface thoroughly without scratching

Ensure inspection or heavy mechanical cleaning is required before proceeding

Record baffle positions before dismantling for correct reassembly

Pull out the ladder formed by uprights and baffle plates

Remove triangular PTFE cord gaskets from longitudinal girder lining

Remove the complete baffle cage

Clean the triangular groove of the longitudinal girder lining and remove grease

Ensure the Compabloc is empty before opening.

Collect remaining fluid to prevent environmental pollution.

Are both circuits completely drained?

Are both circuits not pressurized and drains open?

Mark panels with identification symbols for correct re-installation.

Ensure panel is secured and cannot fall when unscrewed.

Fix the Compabloc to the floor to prevent tilting during dismantling.

Ensure all original components are reassembled

Verify the following components are fully tightened

Enter the design pressure indicated on the nameplate

Is the first circuit empty and the second circuit full and pressurized at design pressure?

Is the maximum allowed differential pressure not exceeded during the test?

Pressurize the second circuit to secure the differential pressure

Supervision of Key Process Parameters

Record the temperature of the heat exchanger

Record the pressure drop across the heat exchanger

Is there any contamination of media observed?

Inspect the following for proper condition

Is there any vibration or pulsation in the pipelines?

Is there any abnormal sound or noise inside the unit?
