Blue screw-plug immersion heater, 19 in long, brass plug, copper sheath

Vulcan

Vulcan AUW230B 19 in 240 V 3000 W HVAC control

SKU CH-A3XZ-5QPDR

Screw-plug immersion heater with 3000 W output at 240 V, 19 in length and copper sheath

  • 3000 W output heats fluids quickly
  • 240 V single-phase supply suits standard circuits
  • 19 in overall length fits common tank openings
  • 60–250 °F control range covers diverse process needs
  • Moisture-resistant terminal enclosure protects wiring in damp areas

Screw-plug immersion heater, 3 000 W

This Vulcan AUW230B screw-plug immersion heater delivers 3 000 W at 240 V AC single phase. A copper sheath and brass plug resist corrosion in liquid heating duties. The moisture-resistant terminal enclosure suits damp plant rooms. It is built for industrial process heating and HVAC pre-heat circuits.

Verify voltage, phase and mounting before ordering

Confirm the supply is 240 V AC single phase and that a 2 in NPT port is available. The unit requires a minimum immersion depth of 11 7/8 in, so check tank dimensions. Ensure the 48 W/sq in watt density matches the fluid type and flow conditions. The control range runs from 60 to 250 degrees F.

Suits plants needing a 19 in copper-sheathed element

Process engineers replacing a like-for-like 19 in heater with moisture-resistant terminals will find this a direct fit. Buyers who need a different sheath material, a lower watt density or a longer element should look elsewhere. Anyone without a 2 in NPT opening or the required immersion depth must choose another model.

Questions about this item

What comes with the Vulcan AUW230B immersion heater and what must be purchased separately?

The unit includes the copper-sheathed heating element with brass 2 in NPT screw plug and a moisture-resistant terminal enclosure; a low-water cut-off control is available as a separate model selection.

Which voltage and wattage version of the AUW230B should I select for a 240 V single-phase supply?

Choose the 240 V AC, 1-phase, 3,000 W model listed in the specifications; it matches a standard 240 V single-phase circuit.

What does the 48 W/sq in watt density mean for real-world heating performance?

A density of 48 W/sq in indicates a relatively high heat flux, so the element must remain submerged at least 11 7/8 in to avoid overheating and ensure proper heat transfer.
