At WCR all gaskets that are glued in are heat cured under pressure for three to four hours in an industrial oven. Depending on the adhesive used and the gasket and plate material the curing temperature is between 280-310 degrees Fahrenheit. If the adhesive is not properly heat cured under pressure gaskets will often fall off during installation resulting in more down-time which equals loss of production. One of the major benefits of the plate heat exchanger is that it is designed for opening, washing and reassembly without having to replace gaskets. If oven curing has not been performed it is most likely the gaskets will end up on the floor when the heat exchanger is opened. Again this is unnecessary down-time and often very costly. Correct heat curing increases the lifetime of the gasket by up to 10 times that of ordinary rubber glue without curing.
