Heat Exchange Units

Heat exchangers transfer thermal energy between two or more fluid streams without mixing them, serving as critical components in petrochemical refining, HVAC systems, power generation, and food processing. Shell-and-tube, plate, and finned-tube configurations each fall under this heading, and the correct classification often hinges on the exchanger's construction type and intended service environment. Units destined for oil-and-gas or chemical plant applications may be subject to Section 301 tariff exposure depending on country of origin, making origin documentation a key compliance step.
