Tempco HDL00007 Cartridge Immersion Heater 500 W 120 V 35 W/sq in 266 °F 7-7/8 in
Heats water to 266 °F using a 500 W, 120 V Incoloy cartridge with 35 W/sq in density and 1/2 in NPT brass screw plug
- 500 W output delivers strong heating power
- 35 W/sq in density ensures efficient heat transfer
- 120 V AC supply fits standard single-phase circuits
- 266 °F control range suits hot-water applications
- 7-7/8 in immersion depth matches tank requirements
Application Fit
This cartridge immersion heater delivers 500 watts at 120 volts AC for direct liquid heating. It suits industrial processes that require a 1/2 inch NPT fitting and a minimum immersion depth of 7 7/8 inches. The Incoloy sheath and PTFE flange resist corrosion in water-based systems. Buyers needing a different voltage, wattage, or thread size should select another model.
Upgrade Context
The unit replaces an existing cartridge heater with the same 1/2 inch NPT connection and immersion length. The jump is worthwhile when the current heater cannot reach 266 degrees Fahrenheit or when its watt density falls below 35 watts per square inch. It also fits installations where an epoxy-sealed lead end is required for moisture protection.
Sustained Operation
At the rated 35 watts per square inch the sheath temperature stabilises during continuous immersion in water. The brass screw plug and PTFE flange maintain a seal at the 266 degree Fahrenheit control limit. The epoxy seal at the lead end prevents moisture ingress over long duty cycles. Performance assumes adequate fluid flow across the Incoloy sheath.

Questions about this item
What thread size does the 1/2 in NPT screw plug require for mounting?
The heater uses a 1/2 in NPT brass screw plug, so the mounting port must match that thread specification.
Which step is often missed when installing the Incoloy sheath heater with PTFE flange?
Ensure the minimum immersion depth of 7 7/8 in is met before tightening the screw plug, otherwise the epoxy seal at the lead end can overheat.
How often should the epoxy seal at the lead end be inspected on this 500 W 120 V heater?
Check the epoxy seal during routine maintenance cycles; replace the heater if the seal shows cracking or moisture ingress.
