Centorr Vacuum Industries (Nashua, N.H.) has shipped three precision Workhorse® vacuum brazing furnaces to CeramTec North America (Laurens, S.C.). The standard Workhorse® design was completely upgraded for CeramTec to achieve precision brazing and heat treating. The improved components include thermocouple survey ports, dedicated load thermocouple, cooling fan and a special partial pressure control system. This control system reduces the chance of damage to the hot zone due to vaporization of lower melting temperature constituents in braze filler metals. The unit also included digital water-flow switches, improved air handling package, Varian diffusion pump, Leybold mechanical pumping system and many other improvements. The system is outfitted with a computer and HMI control system for easy recipe generation, controller configuration and data-recording functions.
