MAINTENANCE COOLER

Note
Observe the plant- and process-specific safety measures before carrying out maintenance work!
Warning
The ECP 1150M coolers do not require special maintenance intervals.
Depending on the degree of contamination of the ambient air, the cooling fin block must be cleaned from
time to time with compressed air.

15.1.1 REPLACING THE HEAT EXCHANGERS

Removal of the heat exchangers may be necessary to carry out maintenance or repair work.
We recommend the following procedures and in this order for replacement of the heat exchangers:
1. Release the upper gas connections and lower condensate connections;
Warning
2. Pull the heat exchangers upwards with rotation out of the cooling block;
Replace the heat exchangers as follows:
1. Dry and clean the push-in opening in the aluminium cooling block with a cloth;
2. Smear the push-in opening with a thin and equal layer of thermal conductivity paste (Part No.
90K0115);
3. Smear the heat exchangers with a thin and equal layer over the whole surface with thermal
conductivity paste (Part No. 90K0115) to ensure good conduction of heat. It is best to close off
the condensate removal of the heat exchangers tube with adhesive tape to prevent any of the
thermal conductivity paste from getting into the heat exchanger;
