Dry-Type Transformer Surplus Values 2026: Complete Pricing Guide

Dry-Type Transformer Surplus Market 2026

Dry-type transformers are essential components of every data center's power distribution system, stepping voltage down from utility levels to the 208V or 480V required by IT equipment. When data centers are decommissioned or upgraded, these transformers represent significant recoverable value — often $2,000 to $80,000+ per unit depending on kVA rating and condition.

The critical decision facing facility managers is whether to sell transformers as surplus equipment (for reuse) or as scrap (for material recovery). In almost every case, selling as surplus generates 3-10x more revenue than scrapping. A 500 kVA dry-type transformer might yield $800-$1,200 as copper scrap, but $8,000-$18,000 as surplus equipment. Understanding this difference can mean tens of thousands of dollars in additional recovery.

DataCenterDecommissioning.ai purchases dry-type transformers from data centers and industrial facilities nationwide. We evaluate each transformer based on its kVA rating, voltage configuration, manufacturer, age, and condition to provide maximum surplus value rather than scrap pricing.

Surplus Values by kVA Rating

75 kVA transformers (480V to 208Y/120V) sell for $1,500 to $4,000 as surplus. These smaller units are common in server room applications and are in consistent demand for small data center builds and commercial electrical projects.

112.5 kVA transformers sell for $2,000 to $5,500. This is one of the most popular sizes for data center PDU feeds and commands steady demand on the secondary market.

150 kVA transformers sell for $2,500 to $7,000. Increasingly common in modern data center designs, these units support higher-density rack configurations.

225 kVA transformers sell for $3,500 to $9,000. This size is the workhorse of data center power distribution and is in very high demand on the secondary market.

500 kVA transformers sell for $6,000 to $18,000. These large units serve as main distribution transformers in data centers and command premium prices due to their capacity and the cost of new equivalents.

750 kVA and 1000 kVA transformers sell for $10,000 to $35,000 and $15,000 to $50,000 respectively. These largest dry-type units are found in major data center facilities and represent the highest individual transformer values.

1500 kVA and above transformers sell for $20,000 to $80,000+. These massive units are typically custom-ordered and command exceptional prices when available on the secondary market.

Surplus vs. Scrap: Why It Matters

The difference between surplus value and scrap value for dry-type transformers is dramatic. Scrap value is based solely on the weight of copper and aluminum in the windings and core — typically $0.50 to $1.50 per pound of total transformer weight. A 500 kVA transformer weighing 3,000 lbs might yield $1,500 to $4,500 as scrap.

Surplus value, by contrast, reflects the transformer's utility as a functioning piece of electrical equipment. That same 500 kVA transformer is worth $6,000 to $18,000 as surplus — 3 to 10 times more than scrap value. The difference represents the manufacturing cost, testing, and certification that went into producing the transformer.

DataCenterDecommissioning.ai always evaluates transformers for surplus potential before considering scrap value. Only transformers with severe physical damage, fire damage, or obsolete voltage configurations are valued at scrap rates. Contact us before scrapping any transformer to ensure you are not leaving money on the table.

How to Sell Your Dry-Type Transformers

To get a quote, provide us with the kVA rating, primary and secondary voltages, manufacturer, approximate age, and condition. Photos of the nameplate are extremely helpful for accurate identification and pricing.

We purchase transformers from all major manufacturers including Square D, Eaton/Cutler-Hammer, ABB, Hammond, GE, Siemens, and Federal Pacific. All voltage configurations are considered, though 480V primary to 208Y/120V secondary is the most common and most valuable for data center applications.
