"Heat exchanger" covers a wide family of equipment. Choosing the right type starts with understanding what each does best.
Here's an overview focused on the finned-tube exchangers used in HVAC and process cooling.
Finned-tube heat exchangers
The workhorse of air-side heat transfer: fluid in the tubes, air across the fins. Ideal for process cooling, air heating and heat recovery. This is AGH's core industrial heat exchanger product.
Process cooling vs heat recovery
Some exchangers reject unwanted process heat; others reclaim it to pre-heat air or water and cut energy costs. The construction is similar; the duty and placement differ.
Material choices
Copper tubes suit most duties; stainless steel handles corrosive or hygienic processes. Fin coatings extend life in aggressive atmospheres.
Getting the sizing right
An exchanger must be sized to your fluids, flow rates, temperatures and pressures. Share those and let engineering size it — or opt for a fully custom-built exchanger.
Key takeaways
- Finned-tube exchangers dominate air-side duty
- Recovery exchangers reclaim heat and cut energy use
- Copper for most duty, stainless for corrosive/hygienic
- Size to real fluid and pressure conditions
