- A heat exchanger is the core device enabling heat recovery and process heating or cooling by transferring thermal energy between two or more fluids. The right type directly determines efficiency, footprint and lifetime cost.
- Plate heat exchangers - very high transfer area in a small footprint; ideal for liquids and hygienic service. Shell-and-tube - robust and easy to clean; preferred for high-pressure and high-temperature duties. Rotary regenerative wheels - best for large air-to-air recovery in HVAC and drying. Air-to-air recuperators - recover exhaust heat to preheat combustion or ventilation air. Microchannel - lightweight, high-performance designs for automotive and refrigeration.
- Define the duty first: fluids, temperatures, pressures, flow rates and fouling potential. Then balance efficiency against cleanability and cost. For an industrial heat recovery project, air-to-air wheels or plates usually lead; for process liquids, shell-and-tube or plates dominate.
- A heat exchanger is only as good as its system integration. Couple it with controls that track temperature differentials, and size recoverable streams conservatively. Our heat recovery guide explains how to map sources and sinks for maximum savings.
- Schedule fouling inspections aligned with duty severity Use clean-in-place (CIP) for plate units Monitor pressure drop as an early fouling indicator Verify gaskets and seals annually
- Plate or shell-and-tube? Choose plates for compactness and liquids; shell-and-tube for harsh, high-pressure or easy-clean needs. How much can recovery save? Well-designed systems commonly recover 20-70% of available waste heat.
