What is Plate Fin Heat Exchanger? What is a Plate Fin Heat Exchanger (PFHE)? A Plate Fin Heat Exchanger (PFHE), also known as a Aluminium Brazed Heat Exchanger, is a type of compact heat exchanger characterized by its very high heat transfer surface area to volume ratio. It consists of corrugated fins sandwiched between parallel...

What is Plate and Frame Heat Exchanger? What is a Plate and Frame Heat Exchanger (P&FHE)? A Plate and Frame Heat Exchanger is the most common type of gasketed plate heat exchanger (gasketed PHE). It consists of a pack of corrugated metal plates clamped together in a frame. The name “plate and frame” specifically...

What is Double-Pipe (Hairpin) Heat Exchanger? A Double-Pipe Heat Exchanger is the simplest type of heat exchanger in its construction. It consists of one pipe mounted concentrically inside another, larger pipe. The two fluids flow through the exchanger: one through the inner pipe and the other through the annular space (the gap) between...

What is Air Cooled Heat Exchanger (ACHE / Fin-Fan)? An Air-Cooled Heat Exchanger (ACHE), often nicknamed a Fin-Fan, is a type of heat rejection device that uses ambient air as the cooling medium to cool or condense a process fluid. Instead of using water, it uses mechanical fans to force or draw air across a bundle of […]

What is Plate Heat Exchanger (PHE)? What is a Plate Heat Exchanger (PHE)? A Plate Heat Exchanger (PHE) is a type of compact heat exchanger that uses a series of thin, corrugated metal plates stacked together to transfer heat between two fluids. The plates are clamped in a frame, creating parallel flow channels for the fluids to […]
