Solar Atmospheres expands California operations with new 10-bar vacuum furnace

Solar Atmospheres is pleased to announce the installation and full commissioning of a new 10-bar vacuum furnace at its Fontana, California facility, further expanding the company’s high-pressure vacuum heat treating capabilities in the western United States.

The furnace, manufactured by sister company Solar Manufacturing, is a state-of-the-art horizontal vacuum system featuring a 48” wide x 48” high x 96” deep hot zone and a maximum load capacity of 12,000 pounds. Equipped with an advanced vacuum pumping package capable of achieving an ultimate vacuum level of 1x10⁻⁶ Torr, the system is ideally suited for processing titanium and other high-performance alloys that require exceptionally clean, tightly controlled vacuum environments.

“This investment gives our customers another regional solution for high-pressure quenching of large components and heavy workloads,” said Derek Dennis, President of Solar Atmospheres California. “It also allows us to drive greater efficiency and cost competitiveness through increased capacity and economies of scale. This addition reflects our continued commitment to innovation, quality, and delivering measurable value to our customers.”

The new furnace strengthens Solar Atmospheres’ ability to support aerospace, defense, medical, and power generation markets with advanced vacuum heat treating technology and reliable turnaround performance.
