Product Developments

Part one

Producing better products and raising the expectation level of an entire industry.

An idealist and perfectionist, Henry Rowan pushed himself and his team to develop groundbreaking new technologies under intense deadline pressures, often taking huge risks to get the order and satisfy the customer.

1950s

1954

Inductotherm introduces the Inductomelter spark gap high-frequency converter.

1955

Inductotherm introduces the first double push-out removable crucible furnace for non-ferrous melting.

1957

Inductotherm is the first to develop a pre-packaged power control for coreless melting in which all components are pre-engineered and pre-tested for immediate installation.

1959

Inductotherm introduces the Linemelt channel-type induction melting and duplexing furnaces.

Inductotherm is the first to use Hollow Bar construction.

I don’t believe in destiny, the notion that we all have an unalterable role in history awaiting us. From what I’ve seen, the most significant turning points in our lives are functions of pure chance and circumstance; success or failure depends on how we deal with both.

1975

Inductotherm introduces the Dura-Line furnace.

1976

Inductotherm introduces the first induction inverter engineered to put full power on a cold charge, the VIP Power-Trak.

1977

Inductotherm introduces three of the first highest powered (23,000 kW) power supplies installed on 70-ton furnaces.

1978

Inductotherm introduces the Automatic Meter Calculator to indicate condition of channel-type inductors.

Inductoheat introduces the SP5 Power Supply – major breakthrough in technology with hockey puck style rectifiers.

I’ve never been content with the status quo. I have never said to myself, “This is the best that we can do.” In fact, to my way of thinking, satisfaction has always been the enemy of progress. It’s not the satisfied man who invents the steam engine, or devises a new way to melt metal or, for that matter composes a symphony. It’s the perfectionist who’s dissatisfied with what has been done before and wants to do things better.
