I am working on a chiller with a plate and frame heat exchanger on the leaving water side of the chiller. I am starting to trip on freezestat and want to clean the heat exchanger. I have never taken one apart and would love some advice on what to do and not do from others who have. This is a fairly large heat exchanger and I already purchased some new gaskets just in case. Wondering how you handle the plates once you take it apart to prevent damage while cleaning. Thank you in advance for any help.
