PLATE HEAT EXCHANGER (OPTION)
Cleaning of plate exchanger
Soldered heat exchanger: For the removal of lime- and rust deposits, purifying agent SWEPcip AS, RS,
CS or S (according to material) is suitable. Cleaning may be performed by means of SWEP cleaning
device C.I.P 90 (circulation method) or a stationary pump.
Screwed heat-exchanger: In this case the heat exchanger can also be disassembled for cleaning.
See attached concept for further technical data.
