Chromalox TDH-42CM Immersion Heater

Chromalox TDH-42CM Immersion Heater is a high‑power direct‑immersion heating element rated at 42 kW for 600 V AC, designed to heat liquids in industrial tanks by placing the element directly into the process fluid. The Mfr part number TDH-42CM appears on distributor listings as a 42 kW, 600 V AC Chromalox immersion heater; several listings identify this model as discontinued, a factor for maintenance planning and spares. Direct immersion heaters, including those in Chromalox's Small Tank & Specialty line, heat liquids and viscous fluids by direct contact with tubular heating elements, enabling rapid heat transfer in tank‑based processes. This family of products emphasizes robust construction for industrial environments and compatibility with control systems and safety enclosures, making the TDH‑42CM suitable where high heat input and compact form factor are required in a tank or vessel.
