Solar Manufacturing announced the sale of a Model HFL-5748-2EQ vacuum heat-treating and brazing furnace to a commercial heat-treating company located in the mid-Atlantic region. The furnace has a work zone that measures 36 inches wide x 36 inches high x 48 inches deep with an operating temperature up to 2500°F and a workload capacity of 5,000 pounds. The hot-zone insulation package will be a CFC hot face backed by six layers of ½-inch graphite felt all housed in a 304 stainless steel support ring.

A large mechanical pump, booster pump and diffusion-pump system is included for vacuum operation to the low 10-5 torr range. In addition, the diffusion-pump heaters are monitored and controlled by a Solar ConserVac system for minimal power consumption. The external gas-cooling system incorporates a 150-HP blower motor and supporting heat exchanger for rapid cooling of the workload at 2-bar gas pressures.
