How to install E18 Plate Heat Exchanger When Maintance?

1 Disconnect pipework from pressure plate
• disconnect pipework from pressure plate
Taking Out Heat Exchanger Plates
• remove the nuts (12a) versus clockwise
• losen all nuts for tensioning bolt (12) crosswise
• unscrew nuts for tensioning bolt (12) from tensioning bolt (1)
• remove washer for tie bar (13)
• remove tensioning bolts (1)
• push pressure plate (10) away from plate pack
• swing out first heat exchanger plate at bottom 20 - 30 cm in longitudal
direction [1]
• swing out plate laterally under an angle of
30 - 45° [2]
• take the plate off the frame
• remove plate by plate in the same manner
• observe the sequence and face position of plates - after cleaning they must be
installed back the same way

2 Cleaning of Heat Exchanger Plates

• rinse each plate with a suitable detergent (must neither attack gasket nor plate) information about suitable detergents can be obtained from Heat Exchanger manufacturer

• clean plates with a soft brush

• gaskets not to be exchanged:

- avoid soaking of plate in cleaning solution

• gaskets to be exchanged:

- soak plate in hot cleaning solution (approx. 100°C)

• at thick layers of scaling :

- soak plate in hot cleaning solution (approx. 100°C)

DO NOT use:

- steel brush

- steel scraper or similar

3 Re-assembling

• re-install again the cleaned plates

observe

- original sequence and position of each plate (as per numbers and plate arrangement drawing)

- gaskets installed and in good order

• fit individual plates (lateral insertion under 30 - 40°inclination)

• push pressure plate (10) to the plate plack

• re-insert tensioning bolts (1) back in lateral slots

• fit washers for tensioning bolt (13) to the tensioning bolts (1)

• tension the plate pack with the nuts for tensioning bolt (12)

- uniformly

- crosswise

- observe parallelism between pressure plate (10) and frame plate (4)

• observe tesnioning limit on name plate

• avoid:

- overtensioning (below min. tensioning limit on name plate)

- too little tensioning (above max. tensioning limit on name plate)

• fix the nuts for tensioning bolt (12) by mounting the nuts (12a)

• connect pipework again

• start up Heat Exchanger as per section 6
