Threaded Inline Air Heaters

Threaded in-line air heaters are designed for industrial process heating applications requiring high-heat and high air pressure. Serpentine™ heating elements are installed into a 304 stainless steel housing and threaded at both ends. TUTCO SureHeat offer two styles, Style “A” and Style “B” inline air heaters. Style “A” should be used when a leak-proof air system is required.

Threaded inline air heaters are commonly connected to filtered compressed air supply lines and rapidly heat air for precise temperature control inline with heated industrial processes.

Additional Info

Make sure to properly mount the TC coupling so that the TC is slightly above the ceramic rod running through the center of the Serpentine™ heating element. The open end of the TC should be in the heated air stream.

The inlet side of the heater is located closest to the power feed throughs. Installation orientation is critical. Positioning the heater in the wrong direction will cause damage. Like all Tutco SureHeat heaters, do not operate without the air on.
