Cleaning-In-Place (CIP)
The Cleaning-In-Place (CIP) equipment permits
cleaning of the plate heat exchanger without opening
it.
If CIP cannot be done, cleaning must be performed
manually, see section “Manual cleaning”.
CIP performs
• cleaning of fouling and descaling of lime deposits
• passivation of cleaned surfaces to reduce sus-
ceptibility to corrosion
• neutralization of cleaning liquids before draining.
Follow the instructions of the CIP equipment.
