Tips For Plate-and-Frame Heat Exchangers

Evaluating your process will help you specify a plate-and-frame heat exchanger that is right for your application. Use these 10 tips to specify your next plate heat exchanger and maximize its service life.

It is no surprise that plate-and-frame heat exchangers (PHEs) offer good heat transfer. But, there are several important factors you must keep in mind as a specifier or user of PHEs. For instance, if the PHE is to be used in conjunction with a cooling tower, it should be designed for the water treatment chemicals being used to treat the tower water. Also, it is easier to prevent a heat exchanger from leaking than to stop a leak once it occurs. And, did you know that you can minimize erosion in the port area by lowering nozzle velocities?
Consider the following 10 tips when choosing and using your next plate-and-frame heat exchanger.

Figure 1. Two liquid streams enter and exit a heat exchanger from the hot side and the cold side. As a result, there are four temperatures to consider when sizing the heat exchanger: hot side inlet, hot side outlet, cold side inlet and cold side outlet.
