Reconditioning is the service performed to the plates inside of a gasketed plate heat exchanger.  Our team removes gaskets, chemically cleans plates, and checks plates for cracks under a special process.  Any cracked plates get replaced.  These plates and the reconditioned plates get re-gasketed, crated, and sent back to the customer to be put back into service.

Repair refers to the services performed to the plate heat exchanger frame.  It includes inspection, refurbishment, replacement of connection linings, and replacement of bolts or other frame parts.

While refurbishment of plates must take place at an authorized service center, some repairs can be performed onsite.  Please contact customer service for more information.
