Finned tube steam air heater/air preheater with round tube mainly uses steel-aluminum finned tube or stainless steel finned tube as the main element for heat exchange. It takes the advantage of the pressure endurance characteristic of steel and high thermal conductivity of aluminum, aims to transfer the heat from steam to air. High efficiency of heat transfer and compact structure are the main advantage of steam coil air heaters.

Steam air heater with elliptical tube
1. Product Introduction
Steam coil air heater/air preheater with elliptical tube mainly uses elliptical steel as core
tube, and hot-dip galvanized steel as the main element for heat exchange. It takes the
advantage of the pressure endurance characteristic of steel and use fins to increase the
transfer area, aims to transfer the heat from steam to air. High efficiency of heat transfer
and compact structure are the main advantage of finned tube steam heat exchangers.
2. Field of Application
