Abstract
A method for detecting the presence of a leak between two fluid paths of an assembled plate heat exchanger by evacuating one or both fluid paths to a low pressure, introducing a test gas to one of the fluid paths to create a pressure differential between the fluid paths, and testing for the presence of test gas in the second fluid path.
