Can anyone help with this..

We have split cooler/evaporator tubes on on offshore carrier chiller and a load of water has gone through the system. The screw compressor has seized and will be replaced, the condenser will be water jetted clean with hot soapy water but since the water has entered the chilled water side our concern is it has gone through the AHU s control valves and now un sure what to do.

Anyone had to perform this type of job/maintenance before, love to hear your advice as what to do from step A-Z.
