When to use a Plate & Frame heat exchanger?
A Plate & Frame heat exchanger consists of a series of gasketed corrugated plates “sandwiched” between 2 headers and held together with tie bolts. The hot and cold fluid – admitted through portholes – flow in the channels between the plates. An alternate flowing arrangement ensures true counter-current flow pattern. The units are ideally suited for liquid to liquid heat transfer requirements with a close temperature approach. The high turbulence (induced by the plate corrugation) yields high heat transfer coefficients resulting in a very efficient heat transfer. Application range is limited by: temperature (gasket material), clean liquids (suspended particles, fibers, etc.
