Centorr Vacuum Industries

What Centorr Vacuum Industries does

Centorr Vacuum Industries is a privately held, Nashua, New Hampshire-based manufacturer of high-temperature vacuum and controlled-atmosphere furnaces, tracing its origin to Vacuum Industries, Inc. (founded 1954) and Centorr Furnaces (founded 1962), which merged in 1991 and were later taken private via a management buyout from LOI Group in 1997. The company designs and builds standard and fully custom-engineered furnace systems operating from 1000°C to 3000°C at vacuum levels of 10^-5 to 10^-6 Torr, covering production furnaces, laboratory/R&D furnaces, continuous belt and pusher furnaces, and hot press systems. Core product families include the Workhorse® general-purpose batch furnace, Sintervac® sintering furnaces, MIM-Vac™ and Injectavac™ debind-and-sinter systems for metal injection molding, Sintervac AM™ and Workhorse AM™ lines for additive manufacturing, CVD/CVI furnaces, graphitization furnaces up to 3000°C, and induction melting systems. Centorr is one of the last builders in its niche still fabricating hot zones in-house, supported by metal and graphite craftsmen with 150+ years of combined experience.
