Industrial HVAC Heating Element
The Tempco TSP02093 is a screw plug immersion heater rated at 12000W for 480V three-phase AC supply. It is built for direct tank or vessel installation where controlled liquid heating is required. The unit suits industrial maintenance teams and HVAC technicians needing a high-wattage immersion solution.
Copper Sheath With Brass Fitting
A copper sheath and brass screw plug provide the wetted surfaces, while a 44.04 W/sq in watt density defines the heat flux. Recompacted element bends restore insulation resistance after forming, and a silicone resin element seal is fitted as standard. Corrosion-resistant electrical wiring hardware completes the assembly for durability in heated fluid circuits.
NEMA 1 Enclosure And 2 1/2 NPT Mount
The heater carries a NEMA 1 enclosure rating and mounts via a 2 1/2 in NPT thread, requiring a minimum immersion depth of 32 1/4 in. Overall length reaches 39 5/16 in, and the control range spans 60 to 250 degrees F. Buyers needing a smaller thread size, lower voltage, or a higher ingress protection rating must select a different model.

Questions about this item
How often will the copper sheath and brass screw plug need inspection or replacement?
The copper sheath and brass screw plug are built for corrosion resistance; periodic visual checks for scale buildup or pitting are recommended, but no fixed replacement interval is defined by the manufacturer.
What limits continuous operation at the 12,000 W rating?
The 44.04 W/sq in watt density and 32 1/4 in minimum immersion depth set the thermal boundary; operating below that depth or with restricted flow will trip the high-limit protection first.
How much heat does the NEMA 1 enclosure add to the mechanical room during all-day runs?
At 12,000 W the heater rejects nearly all input energy as heat into the fluid; the NEMA 1 enclosure itself dissipates only a small fraction, so room temperature rise depends almost entirely on the heated fluid loop.
