A finned tube heat exchanger for a coater is a heat transfer device used in industrial coating machines to heat or cool the process air required for coating, drying, or curing operations. It consists of tubes carrying a heating or cooling medium—such as steam, hot water, thermal oil, or chilled water—with metal fins attached to the outside of the tubes to increase the effective heat transfer surface.
In a coating line, large volumes of air must be precisely temperature-controlled and evenly distributed across the coated material. The finned tube heat exchanger transfers thermal energy from the fluid inside the tubes to the airflow passing over the fins (or vice versa), enabling uniform air temperature, stable process conditions, and high energy efficiency.
These heat exchangers are widely used in:
Coating ovens and drying tunnels
Roll-to-roll and film coating machines
Paint, adhesive, and battery electrode coating lines
Their compact structure, high heat transfer efficiency, and ability to be customized for specific airflow and temperature requirements make finned tube heat exchangers a standard thermal solution in modern coater systems.
