Plate & frame exchanger panas dumadi saka piring transfer panas (piring logam corrugated) sing disegel dening gaskets, tightened bebarengan dening rod dasi karo kacang ngunci antarane piring pigura. Bolongan port ing piring mbentuk jalur aliran sing terus-terusan, cairan kasebut mlebu ing dalan saka inlet lan disebarake menyang saluran aliran antarane piring transfer panas. Cairan loro kasebut mili ing arus counter. Panas ditransfer saka sisih panas menyang sisih kadhemen liwat piring transfer panas, cairan panas digawe adhem lan cairan adhem digawe panas.
