Caltherm changes name to reflect global customer base

Caltherm Corp., a local manufacturer of thermal and pressure control devices, is changing its name effective today to Vernet USA, which relates back to the company’s European roots.

Vernet and Caltherm have been part of Magnum Corp. since 1972, company officials said. The name change is designed to better align the company with its global customer base, company officials said.

The company’s building signage is being changed to reflect the new name, but no personnel or staffing changes are planned, said Chris Anders, sales and marketing manager.

The company designs, manufactures and engineers a variety of water, fuel, coolant, oil and air flow control products beginning in 1972 as a subsidiary of its sister company Vernet, headquartered in Ollainville, France.

Caltherm, 910 S. Gladstone Ave., began manufacturing operations in Columbus in 1976, to supply thermostats to the diesel engine industry. It was the first manufacturing company recruited by the Columbus Economic Development Board.
