Fast offers
A written offer the same business day, based on your photographs.
Dedicated logistics
Our own crew, trailer and crane, not a brokered haul.
No broker fees
One buyer from first call to cleared pad, with nothing skimmed.
How it works
Six steps from photograph to payment
- 01
Take pictures
Photograph the nameplate, the inside of the cabinet and the tank from both ends. Four frames on a phone are enough to price most units.
- 02
Send them to us
Email or text the photographs with the site address and whether the unit is still energised. We reply the same business day with questions or a number.
- 03
Review the offer
The offer names the unit, the site, the price and the pickup window. It is written, dated and good for thirty days unless the unit changes hands.
- 04
We schedule freight
A crew, a trailer and a crane if the pad needs one. You get the date and the arrival window, and the site does not have to close for it.
- 05
Testing on arrival
Winding resistance, insulation resistance and a turns ratio check, plus oil analysis where the unit is liquid-filled. Results travel with the unit.
- 06
Get paid
Payment is released against the signed bill of sale and the scale ticket, by check or ACH, with the paperwork copy left on site.
What we handle
The parts sellers dread
Rigging
Crane, skates and a route survey for anything that will not roll onto a trailer.
Oil containment
Pans, absorbent and a spill plan before a drain plug is touched.
Bill of sale
A document that clears a lien, a lease or a bankruptcy file, not a handwritten note.
PCB paperwork
Testing and manifesting for pre-1979 oil, handled before the unit moves.
On the ground
The unit itself
A furnace transformer feeds an electric arc or induction furnace rather than an ordinary plant distribution circuit. Arc furnace service commonly combines low secondary voltage with very high current.
Heavy secondary terminals, closely arranged bus connections and substantial cooling equipment reflect the heat and mechanical stress imposed during melting.
Induction furnace arrangements vary: the transformer may feed a converter instead of connecting directly to the furnace coil. Connection drawings establish that distinction.
Tap positions, winding connections and impedance must be read alongside the furnace design; a nameplate alone does not describe how the unit operated through repeated melt cycles.
Local reality
Where you find furnace in this state
North Carolina furnace transformers appear at steel mills, foundries, scrap processors and induction heating shops. In a foundry furnace bay, the tank may sit beside a cooling skid with secondary conductors passing through a wall.
At a scrap-processing site, verify whether the transformer served melting equipment or another plant load.
An induction heating shop may have a transformer dedicated to a billet heater or heat-treatment line, with converter cabinets nearby. Steel mill units can be tied into furnace platforms and crowded bus galleries.
Equipment identification should follow circuit drawings and cable routes, not a handwritten furnace label on the enclosure.
Around the site
Our inspection list
We inspect duty cycle, impedance, tap changer condition, cooling and furnace load history. Melt logs help establish repeated overloads, interrupted heats and operating patterns.
Compare recorded tap positions with the furnace operating schedule, then examine accessible bushings, secondary terminals and bus joints for overheating, cracked insulation or signs of movement.
Cooling inspection includes radiator leaks, pump condition, fan operation and any oil-to-water heat exchanger fitted to the unit. Tap changer maintenance records deserve separate attention because repeated voltage adjustments can wear contacts.
Impedance data and repair reports help explain whether a winding fault or furnace-side event ended the operating run.
Where it sits
Testing, oil and liability
Furnace duty is brutal, and the oil history matters more than the nameplate when judging operating condition. Dated dissolved gas analysis, moisture results and dielectric tests are more useful than an unsupported claim that the oil is clean.
Trends can distinguish a developing thermal problem from a single unusual sample.
Available testing may include winding resistance, ratio checks and insulation measurements, selected by qualified personnel for the unit's condition. PCB documentation, oil-processing records and spill reports belong in the review.
A failed furnace transformer with suspected internal arcing should not be energized merely to demonstrate that it still takes voltage.
On the ground
Load-out and haul
Removal starts at the furnace bay, not at the truck. Qualified crews must isolate the supply, verify absence of voltage and disconnect furnace buswork under the site's electrical safety procedures.
Check whether radiator banks, cooling pipes or secondary terminals obstruct the route from the transformer pad to the loading area.
A lift plan needs verified weight, approved lifting points and the tank's actual condition. Radiators and bushings are not lifting points. Lowboy selection, spreader bar clearance and floor loading require review before movement.
If furnace oil must be drained, containment, labeled containers and responsibility for transport should be settled beforehand.
Local reality
Valuation factors
The assessment considers furnace type, winding material, documented condition, tap changer serviceability and the completeness of cooling equipment. A disconnected tank with missing secondary terminals presents a different recovery task from a complete unit beside its furnace.
Drawings and photographs help separate reusable assemblies from components damaged during shutdown or demolition.
Failure history changes the review. A winding damaged by repeated furnace short circuits raises different concerns than an external bushing failure with documented repair. Oil contamination, distorted bus terminals and inaccessible lifting points also matter.
Removal scope must account for furnace platform access, disconnected cooling lines and any remaining oil.
Around the site
How to start the conversation
The first information package should identify the North Carolina site, furnace process and transformer status: operating, disconnected, failed or already removed. Include legible nameplate photographs, overall tank views and close-ups of secondary connections.
Furnace drawings, tap changer identification and the latest oil report make the initial equipment review more specific.
For a furnace bay removal, describe the loading route, door dimensions, overhead obstructions and whether buswork remains attached. State who controls electrical isolation and provide any known spill or PCB records.
Transformer Buyers NC buys these units across the state, with the equipment review and handling plan based on documented furnace service.

Questions
Straight answers
Equipment types
Can you buy a failed furnace transformer?
We buy failed furnace transformers as well as used, surplus and obsolete units. Describe the furnace-side event, protection operation and visible damage.
Service area
Which records matter for an arc furnace unit?
Useful records include melt logs, furnace load history, tap changer maintenance, impedance data and dated oil analyses. Include cooling-system repairs and any winding or bushing failure reports. These documents show repeated operating stress that the transformer nameplate cannot capture.
Payment
Must furnace buswork be disconnected before removal?
Furnace buswork must be safely disconnected before the transformer moves, but the responsible crew and sequence should be established during planning. Qualified personnel handle isolation and voltage verification. Photographs of bus joints, cooling connections and the loading route help define the removal scope.

Testing, oil and liability: what should a seller know?
Furnace duty is brutal, and the oil history matters more than the nameplate when judging operating condition. Dated dissolved gas analysis, moisture results and dielectric tests are more useful than an unsupported claim that the oil is clean.
