AAON Heat Exchangers transfer thermal energy between air and water (or refrigerant) in heating, cooling, and hot-water systems. This collection features shell-and-tube units, brazed plate heat exchangers, and coil-style exchangers designed for reliable performance in boilers, chillers, and packaged rooftop units. By using genuine Aaon Heat Exchangers, technicians ensure efficient heat transfer, reduce scaling or fouling, and promote consistent temperature control in commercial and industrial settings.
