Detachable Plate Heat Exchangers

Overview

Detachable plate heat exchangers are the most common PHE type, consisting of a frame with fixed and movable plates, guide bars, and tightening bolts. Their key advantage is removable plates for easy cleaning and maintenance, with flexible heat transfer area adjustment by adding or removing plates. Compared to shell-and-tube exchangers, they offer 3-5x higher heat transfer coefficients at equal flow resistance, 1/5 to 1/8 the footprint, and up to 90%+ heat recovery. Operating temperature depends on gasket material (up to 180-230°C), max working pressure typically 2.5 MPa. Widely used in HVAC, chemical, food, marine, and power industries.
