6 Maintenance
To keep the heat exchanger in good condition, regular maintenance is
required. It is recommended to record all maintenance of the heat exchanger.
The plates need to be cleaned on a regular basis. The frequency depends on
several factors such as type of media and temperature.
Different methods can be used for cleaning (refer to Cleaning – Product side
on page 29 and Cleaning – Non-product side on page 32) or reconditioning
can be performed at an Alfa Laval service center.
After a long period of use, it can be required to regasket the heat exchanger.
Refer to
Regasketing on page 42.
Other maintenance that should be performed regulary:
• Keep carrying bar and guiding bar clean with paraffin oil.
• Keep the tightening bolts cleaned.
• The stainless steel surfaces of the frame plate, the pressure plate and
connection plates are glass blasted. Clean with a cloth wetted by paraffin
oil. Do not degrease the surface!
• Lubricate the threads of the tightening bolts with an EP (extreme pressure)
grease. For example, use Gleitmo 800 or its equivalent.
• Grease the suspension wheels on the pressure plate and the connection
plates.
6.1 Cleaning – Product side
Immediately after a production cycle, the product side is normally cleaned
through the circulation of acid and/or lye as a built-in sequence in the
production cycle.
NOTE
After the first test run of the product, the heat exchanger should be
cleaned following a cleaning program applicable to the product in
question. The heat exchanger should then be opened, refer to
Opening on
page 34, and the plate surfaces carefully inspected. The cleaning results
should be checked at regular intervals.
WARNING
Use proper protective equipment, such as safety boots, safety gloves and
eye protection, when using the cleaning agents.
