Reconditioned Transformers

Reconditioned or remanufactured transformers that run like new.

Our experts can help you determine if purchasing a reconditioned or remanufactured transformer is the right option for you. In some cases, a reconditioned transformer offers increased cost efficiency and expediency.

Due to our nation-wide service area, we’re constantly acquiring previously owned transformers, which we put through a comprehensive certification process before making them available to you. Our team of engineers inspect, clean, and refurbish all units, before certifying all products and adding to our catalog.

ELSCO’s certified, pre-owned transformers run from 500 kVA thru 2500 kVA with 2.5, 5, and 15 kVA primaries. All units can also be modified to match your existing line-up. Because of our commitment to quality, we’re proud to include a one-year warranty on all parts and performance.
