Tempco HDL00043 Cartridge Immersion Heater 3000W 240V

SKU CH-0M5W-EGJM5

Cartridge immersion heater delivers 3000 W at 240 V AC with Incoloy sheath and brass screw plug for water heating

  • Delivers 3000 W heating power for demanding industrial applications
  • 189 W/sq in watt density enables rapid thermal response
  • Incoloy sheath resists corrosion in water-based systems
  • Brass screw plug with 3/4 in NPT fits standard tank openings
  • Epoxy-sealed lead end protects connections up to 266 °F control range

Industrial Cartridge Heater

The Tempco HDL00043 is a 3000W cartridge immersion heater built for direct liquid heating in industrial systems. It operates on 240V AC single-phase power and uses an Incoloy sheath with a brass screw plug for durability. The unit is designed for use with water and includes an epoxy seal at the lead end for added protection.

Thermal Performance

This heater delivers a watt density of 189 W/sq in and reaches a control range of 266 Degrees F during operation. The Incoloy sheath resists corrosion while transferring heat efficiently into the fluid. A PTFE flange adds chemical resistance at the mounting point. The design supports continuous immersion at the rated output.

Installation Requirements

The heater fits a 3/4 in NPT opening and requires a minimum immersion depth of 7 1/4 in for safe operation. Overall length is 8 1/4 in, so the tank or vessel must accommodate that insertion. The brass screw plug simplifies mounting in compatible ports. No external controls are included with the unit.

Questions about this item

How do I install the 3/4 in NPT screw plug on the HDL00043 and what step is often missed?

Thread the brass screw plug into a matching 3/4 in NPT port and tighten to seal; the step often missed is ensuring the minimum 7 1/4 in immersion depth so the Incoloy sheath stays fully submerged.

What maintenance or replacement will the 3000 W cartridge heater need over time?

The epoxy seal at the lead end and the PTFE flange can degrade with thermal cycling; plan to inspect the seal annually and replace the cartridge if leakage or insulation resistance loss appears.

What limit appears first during sustained operation at 189 W/sq in?

The control range tops out at 266 °F, so the built-in temperature limit will trip before the sheath or watt density causes damage.
