Custom-configured to the needs, space and duct layout of your plant.

Air-to-air heaters transfer heat from a hot gas to a cold gas. Typically, this method is used for combustion air preheating, which increases the thermal efficiency of industrial systems and processes, and in some cases facilitates proper combustion of difficult fuels. By recapturing heat from combustion products, E-Tech tubular air heaters help you save as much as 2.5% for each 100°F of preheating for combustion air.

Our engineers can custom design your air-to-air heater to meet your exact requirements, while keeping your capital costs to a minimum. Our long-life units use heavy, high-quality carbon steel casing, carbon steel or alloy tubes and flanged air and gas connections. Depending on use, some designs may employ lightweight aluminum tube and fin components. We can incorporate other features, as well, such as dampers and controls.
