Surplus VFD Drives from Factory Closings: What to Expect

When factories close or undergo major restructuring, one of the most valuable assets that often become available on the secondary market is surplus VFD drives from factory closings: what to expect. Variable frequency drives (VFDs) are critical components in industrial automation, offering precise motor speed control and energy savings. For buyers and sellers in the surplus VFD market, understanding the nuances of acquiring drives from factory shutdowns can make the difference between a profitable purchase and a costly mistake. Drawing on over 30 years of experience at Industrial Surplus World, this detailed guide dives deep into the realities of surplus VFD drives from factory closings, what to expect, and how to maximize value.

What Are Surplus VFD Drives from Factory Closings?

Surplus VFD drives from factory closings refer to variable frequency drives that become available when manufacturing plants shut down, relocate, or upgrade their equipment. These drives are typically removed en masse during plant decommissioning or inventory liquidation. Unlike regular surplus equipment, these drives come from installations with known operational histories and often include legacy models no longer in production, as well as newer units.

Industry-wide, VFDs are rated by their horsepower (HP) capacity, voltage class, and control features. The drives found in factory closings vary widely, from fractional horsepower (1/2 HP) units used in small conveyors to 500+ HP drives controlling large industrial motors. Voltage ranges commonly span from 230V single-phase models for light machinery to 480V or 600V three-phase units for heavy-duty applications.

Types and Brands You Can Expect

Major industrial players such as Allen-Bradley (Rockwell Automation), Siemens, Schneider Electric (Altivar series), ABB, and Yaskawa dominate the VFD market. In factory closings, buyers can expect to see:

• Allen-Bradley PowerFlex Series: Models like PowerFlex 40, 70, 700, and 755 are prevalent. For example, the PowerFlex 70 is popular in 5-150 HP ranges, offering rugged IP20 and IP66 enclosures.
• Siemens SINAMICS Series: SINAMICS G120 and G130 models frequently appear. These are modular, scalable drives supporting 0.37 kW to 250 kW (0.5 HP to 335 HP).
• Schneider Electric Altivar Drives: Altivar 312 and 61 models are common, with ratings from 0.75 kW to 132 kW.
• ABB ACS Series: ACS580 and ACS550 models, covering 0.75 kW to 560 kW (1 HP to 750 HP), often come off factory floors.
• Yaskawa V1000 and A1000 Series: Known for high performance in HVAC and general industrial applications.

Knowing the make and model is critical because it influences availability of spare parts, firmware updates, and support. Many legacy models no longer have manufacturer support, which affects their resale value.

Understanding the Condition and Grading of Surplus VFD Drives

One of the essential factors in dealing with surplus VFD drives from factory closings is understanding their condition. Most factory-closing inventory is graded as follows:

• Grade A (Like New): Units that appear unused or barely used, often removed during factory upgrades before commissioning.
• Grade B (Used but Functional): Drives that show typical wear but have been tested and verified operational.
• Grade C (Non-Functional or Parts Only): Drives that may be damaged or missing components, suitable only for parts or repair projects.

Expect most surplus drives from factory closings to be Grade B, as factories often sell off older equipment that still functions but is not up to current production standards. Grade A drives are rarer and command a premium, while Grade C units require buyer expertise for refurbishing.

Technical Specifications to Check Before Buying

When purchasing surplus VFD drives, especially from factory closings, scrutinize the technical specifications to ensure compatibility with your intended applications:

• Voltage Class: Confirm the drive’s rated input voltage matches your power supply. Common ratings are 230V, 460V, and 600V three-phase systems.
• Horsepower (HP) or Kilowatt (kW) Rating: Ensure the drive matches or exceeds the motor size it will control. For example, a 100 HP motor requires a drive rated for at least 100 HP continuous duty.
• Current Rating (Amps): Drives list continuous and peak current ratings on datasheets. Overloading a drive can cause failures.
• Control Features: Check if the drive supports the required control protocols (e.g., Modbus, Ethernet/IP, Profibus). Factory-closing inventory may feature older communication standards.
• Environmental Ratings: Verify enclosure types (NEMA 1, NEMA 12, IP20, IP66) based on your plant environment. Drives from clean indoor factories may not be suitable for harsh environments.

Request datasheets or manuals for the exact models whenever possible. Many manufacturers provide digital archives of legacy product documentation.

Pricing Expectations and Market Trends

Pricing for surplus VFD drives from factory closings varies widely based on condition, brand, and specifications. Here are some ballpark figures based on recent market data and Industrial Surplus World’s experience:

• Fractional HP drives (1/2 to 3 HP): $50 - $200 per unit
• 5 to 20 HP drives: $200 - $700
• 25 to 100 HP drives: $700 - $2,500
• 100 to 500+ HP drives: $2,500 - $10,000+

Prices tend to be 30-60% lower than new equipment list prices, but beware of “too good to be true” deals, which may reflect hidden defects or missing accessories. Factory closings can flood markets temporarily, reducing prices, but quality and warranty issues often arise.

How to Evaluate Surplus VFD Drives from Factory Closings

To make informed purchasing decisions, consider these practical tips:

1. Request Test Reports or Functional Verification: Sellers should provide test data verifying drives operate within specifications. At Industrial Surplus World, we run dynamometer tests on 75% of our VFD inventory.
2. Inspect Physical Condition: Check for signs of overheating, corrosion, or damage. Drives stored improperly during plant shutdowns may have internal moisture damage.
3. Confirm Firmware and Software Compatibility: Some drives require specific software versions for programming and diagnostics.
4. Ensure Availability of Accessories: Input/output filters, braking resistors, and control panels can be costly if missing.
5. Verify Warranty and Return Policies: Surplus sales often are “as-is,” but reputable dealers may offer limited warranties or return options.

Common Challenges in Buying Surplus VFD Drives from Factory Closings

While surplus VFD drives can offer significant cost savings, buyers should be aware of challenges:

• Obsolescence: Drives from closed factories may be outdated models with no manufacturer support or replacement parts.
• Compatibility Issues: Matching drives to motor and control systems can be complex, especially if factory documentation is missing.
• Storage and Handling Damage: Drives may have been stored improperly, leading to capacitor degradation or PCB corrosion.
• Documentation Gaps: Lack of manuals and wiring diagrams complicates installation and programming.

Working with a trusted surplus dealer like Industrial Surplus World helps mitigate these risks through thorough inspection, testing, and expert advice.

Practical Advice for Sellers of Surplus VFD Drives

If you are a plant manager or engineer preparing to liquidate surplus VFD drives from a factory closing, here are key recommendations to maximize return:

1. Inventory Thoroughly: Document make, model, serial number, specs, and condition for every unit.
2. Clean and Inspect: Remove dust, check for corrosion, and ensure drives are dry to enhance buyer confidence.
3. Test Drives: Functional testing and providing detailed test reports increase perceived value.
4. Package Properly: Use anti-static bags and secure shipping crates to prevent damage during transport.
5. Provide Documentation: Include user manuals, wiring diagrams, and programming guides where possible.
6. Partner with Experienced Dealers: Collaborate with trusted surplus equipment brokers who understand VFD market dynamics.

These steps reduce transaction friction and improve sale price while minimizing post-sale disputes.

Environmental and Regulatory Considerations

Disposing or reselling surplus VFD drives from factory closings requires awareness of environmental and regulatory issues. Drives contain electronic components including capacitors and PCBs that must be handled according to EPA rules. The EPA Electronics Donation and Recycling guidelines provide best practices for responsible handling. Buyers should confirm that surplus sellers comply with these requirements to avoid liability.
