Steam heater with round tube
1. General Information
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.
2. Field of Application
-feed drying
-cereals and oil processing
-paper industry
-printing and dyeing industry
3. Specification
Heating source:
low/medium Pressure steam (0.3-2.5MPa)
