Specifying Heat Exchangers: Why Functional Requirements Must Come First
Eugene le Roux (FSAIRAC) and Eamonn Ryan argue that a heat exchanger specification should be built around functional parameters—fluid properties, temperatures, thermal duty, and pressure conditions—rather than physical characteristics alone. Published in RACA Journal, this Part 1 of a two-part series covers the functional side; Part 2 will address the physical interface, mechanical integrity, safety, maintenance, and instrumentation.
