The first system ever built by Ambrell Corp. — a 6 kW induction power supply built in 1986 — has returned to the manufacturer following decommissioning by its owner. It will be displayed at the induction heating system maker headquarters in Rochester, N.Y.

The system, known as Unit #1, was retired by Leonardi Manufacturing, a manufacturer of metal-based solutions.

According to Leonardi Manufacturing, the Ambrell system was in operation every day since 1986. They moved the system to a new facility in 1991, and it remained there until the second half of 2020. “We used the 6 kW system for brazing carbide-to-steel for manufacturing our stump grinding equipment. It has been an incredibly reliable and dependable piece of equipment for almost 35 years,” said Joe Leonardi, Vice President of Leonardi Manufacturing.

It was replaced with Ambrell’s Easyheat induction heating system. “[Unit #1] was critical to our manufacturing process, and its durability and consistent performance is why we chose Ambrell once again.”
