Chromalox 108-304566-001 TDH-18XX Air Ducted Heater

Chromalox 108-304566-001 TDH-18XX Air Ducted Heater is an inline heating element designed to add heat to air as it flows through ductwork in HVAC or process-air systems. This unit is specified for 240 V, three-phase service and carries an 18 W heat output, identifying it as a compact TDH-18XX configuration within Chromalox's TDH air duct heater family. The PN 108-304566-001 uniquely identifies this specific model, intended for installation inside ductwork or air-handling modules to provide controlled heat without occupying expansive space in the system. As with other Chromalox air duct heaters, it is designed to integrate with standard electrical practices for 240 V three-phase equipment and to suit environments where small, steady heat input to moving air is required, such as temperature maintenance in supply ducts or in-process air streams. Chromalox is a long-established supplier of industrial heating solutions, and TDH duct heaters are marketed for reliable inline heating in commercial and industrial HVAC or process applications.
