SELL YOUR VARIABLE FREQUENCY DRIVES
Sell surplus variable frequency drives and AC drives nationwide. We review Allen-Bradley, ABB, Siemens, Eaton, Yaskawa, Danfoss, and other documented VFD inventory.
Surplus Electrical Buyer purchases variable frequency drives, AC drives, adjustable frequency drives, soft starters, regenerative drives, and complete drive cabinets from industrial facilities throughout the United States. We evaluate current models, discontinued drive families, unused project inventory, tested take-outs, and complete drive packages removed during controls upgrades.
A VFD should not be priced as ordinary electronic scrap. Manufacturer, series, horsepower, input voltage, enclosure, option cards, keypad, firmware generation, and operating history can all affect secondary-market demand. A clean drive with a readable nameplate and known operating status is easier to match to plants maintaining an installed base, while an obsolete unit may still have value as a replacement or source of components.
We buy individual drives as well as palletized inventories and complete control-room removals. Sellers commonly include panel shops, electrical contractors, water and wastewater facilities, refineries, paper mills, food plants, mines, HVAC contractors, data centers, and manufacturers completing automation projects. Send clear photos and nameplate information for a fast, no-obligation review.
Types of Variable Frequency Drives We Buy
We evaluate the following equipment categories and related surplus. Items outside this list may also qualify when manufacturer, model, ratings, quantity, and condition are identifiable.
- Low-Voltage AC Drives — 208V, 230V, 460V, 575V, and 600V drives for pumps, fans, conveyors, compressors, and process machinery.
- Medium-Voltage Drives — Drive systems for large motors used in refining, mining, water treatment, power generation, and heavy manufacturing.
- Regenerative and Active-Front-End Drives — Specialty drives designed for braking energy recovery, low harmonic performance, and demanding process loads.
- Soft Starters — Solid-state reduced-voltage starters, bypass contactors, and complete soft-start panels.
- Drive Cabinets and Packages — Configured systems with disconnects, bypasses, reactors, filters, contactors, controls, and cooling equipment.
- Obsolete Replacement Drives — Discontinued families needed by facilities that cannot immediately redesign or replace an existing control system.
Manufacturers We Evaluate
Common manufacturers include Allen-Bradley / Rockwell Automation, ABB, Siemens, Eaton, Yaskawa, Danfoss, Schneider Electric, Toshiba, Mitsubishi Electric, Emerson / Control Techniques. Manufacturer names identify equipment we evaluate; no affiliation or endorsement is implied.
Where Variable Frequency Drives Becomes Surplus
Plant automation upgrades
Controls modernization often leaves serviceable drives, bypass cabinets, and spare units that no longer match the new architecture.
HVAC and pumping projects
Chiller plants, cooling towers, booster pumps, and large air-handling systems generate VFD inventory during efficiency retrofits.
Manufacturing line changes
Conveyor, extrusion, packaging, and process-line changes can release matched groups of drives and motor-control components.
MCC and panel rebuilds
Bucket-mounted drives, soft starters, and loose spares are often removed together when an MCC lineup is reconfigured.
What Affects Market Value
Model and series
Current, supported families generally have broader demand, while some discontinued series are valuable for installed-base replacement.
Horsepower and voltage
The motor horsepower range, input voltage, phase, output current, and duty rating are essential quoting details.
Condition and history
New-in-box, tested, recently operating, untested, and repairable drives are evaluated differently.
Completeness
Keypads, option cards, manuals, bypass hardware, cabinets, reactors, and matched spare parts can improve a package offer.
Quantity and compatibility
Groups of identical or compatible drives are easier to transport, test, and place than unrelated single units.
How to Prepare a Quote Request
Clear specifications and condition details reduce uncertainty and help our purchasing team provide a more useful review. You do not need a formal spreadsheet, but identification matters.
- Photograph the complete drive, front keypad, side and rear condition, and every manufacturer nameplate.
- Record catalog number, horsepower, input voltage, output current, enclosure rating, and any installed option cards.
- State whether the drive is new, tested, recently removed from service, untested, or known to need repair.
- Keep matched bypass cabinets, reactors, filters, manuals, and spare boards with the drive whenever possible.
How the Selling Process Works
- Send specifications and photos. Call (951) 403-5738, text us, or use the online quote form with nameplates, quantities, condition, and location.
- Receive an equipment review. We check compatibility, reuse demand, lot quality, and practical logistics.
- Review the written offer. Equipment included, pickup assumptions, and payment terms are confirmed before scheduling.
- Coordinate pickup. For accepted qualifying lots, we arrange appropriate transportation around your facility schedule.
Frequently Asked Questions
- Do you buy obsolete variable frequency drives?
- Yes. Discontinued VFD families may have replacement value for facilities maintaining existing systems. Send the complete catalog number and clear photos so we can identify demand.
- Do VFDs need to be tested before selling?
- No. We buy new, tested, recently operating, and untested drives. Accurate condition information helps us make the most appropriate offer.
- Do you buy complete VFD cabinets?
- Yes. We buy enclosed drive packages with disconnects, bypass contactors, reactors, filters, cooling, and control components, as well as loose drives.
- What information is needed for a VFD quote?
- Provide manufacturer, catalog number, horsepower, voltage, output current, enclosure, quantity, condition, and photos of the nameplate and keypad.
