What Our Clients Say

We needed a new transformer for our data center expansion that met our technical specs and tight timeline. Northfield delivered the high-capacity unit fast, which relieved a lot of the pressure on us. The entire process was smooth with frequent updates. The attention to detail is much appreciated.

Northfield made and delivered a custom transformer to our solar farm in about 10 months. We had a firm deadline, and they handled the production schedule and logistics to keep us on track. We got it installed just in time.
