Oil-Filled Transformer Buyers
Liquid-filled units — mineral oil, silicone or ester — from 25 kVA pole-mounts up to 20 MVA power transformers. Oil is not a problem for us; containment, testing and disposal are part of what we do.
| Ratings bought | 25 kVA – 20 MVA |
|---|---|
| Fluid types | Mineral oil, silicone, FR3 / natural ester |
| Voltage class | up to 138 kV |
| Cooling classes | ONAN, ONAF, OFAF, KNAN |
| PCB status | Non-PCB and PCB-labeled both accepted |
| Testing | We perform our own oil sampling at our cost |
Selling Oil-Filled Transformers
Why the fluid matters to the offer
A unit's fluid tells us both its value and its handling cost. Non-PCB mineral oil is straightforward. Silicone-filled units are common in indoor vault installations and carry a premium because they are harder to source used. Anything manufactured before 1980 gets treated as PCB-suspect until an oil sample says otherwise, and we pull and pay for that sample.
Containment during removal
Our crews arrive with absorbent, containment berms and drum or vacuum-truck capacity sized to the unit's gallon count. Where a unit must be drained before transport we drain to DOT containers on site. Nothing gets set down on your soil or your storm drain, and you receive the disposal documentation for your file.
Documentation you get back
For any oil-filled purchase we can supply a bill of sale, a transfer of custody record, oil analysis results where we sampled, and where applicable an EPA-compliant disposal manifest. Plant environmental managers usually want this before the unit leaves the fence, so we prepare it as a matter of course.

Other Equipment We Buy
Padmount Transformers
Pad-mounted distribution transformers are the single most liquid item we buy. A dead-front loop-feed unit in the 75 to 2500 kVA range with a legible nameplate and a sound tank can be priced from photographs the same day.
75 kVA – 5000 kVA120–160 dry-type units handled per yearDry-Type Transformers
Ventilated, sealed and cast-coil dry-type units from 15 kVA control transformers up to 5000 kVA unit substation sections. Copper-wound units carry a materially higher offer than aluminum.
15 kVA – 5000 kVA40–60 substation-class units per yearSubstation Transformers
Station-class and power transformers from 1 MVA to 100 MVA, including units with load tap changers, radiator banks and conservator tanks. These are heavy-haul projects and we run them end to end.
1 MVA – 100 MVALots of 10 to 400 units purchased at a timePole-Mount Transformers
Single-phase and three-phase overhead distribution transformers, 5 kVA to 500 kVA. This is a volume item — we buy them by the pallet and by the trailer load out of utility and co-op surplus programs.
5 kVA – 500 kVA25–40 complete lineups per yearUnit Substations
Complete primary-transformer-secondary lineups: incoming section, transformer, and low-voltage switchgear or switchboard bolted as one assembly. We buy them whole and we buy them by the section.
300 kVA – 5000 kVA60–90 cast-coil units per yearCast-Coil Transformers
Epoxy-encapsulated cast-coil units built for harsh, humid and high-load environments. Because they were expensive new and are durable used, they hold value better than any other dry-type.
300 kVA – 10 MVASend the nameplate from your oil-filled transformers and we will return a firm number, usually the same business day. Payment is issued before loading and the rigging is ours.
