Company History

Solar Atmospheres was founded in 1983 by William R. Jones, our Chief Executive Officer. It was a natural outgrowth of his pioneering work as a developer and manufacturer of vacuum furnaces having started Vacuum Furnace Systems (1978) and Solar Manufacturing (2002), Consequently, Solar uses the latest technology in processing parts and is continually investing in new furnace engineering.

In 1992 Solar moved to a new 24,000 square foot building built specifically for vacuum heat treating. 2001 marked the start-up of Solar's second facility in Hermitage (Western PA), which now features five 24-foot long vacuum furnaces, a 36-foot long vacuum furnace, and the world's largest commercial vacuum furnace at 48 feet in length with a load capacity of 150,000 lbs.

In 2007, Solar added vacuum carburizing services at the Souderton plant. To provide the service, a newly engineered insitu vacuum carburizing furnace was developed by Solar's Technology Center in cooperation with Solar Manufacturing.

In 2011, Solar Atmospheres added a third plant site in California. The plant primarily services the aerospace, medical and oil industries.

In 2015, Solar Atmospheres opened its 4th location in Greenville, SC. The facility is 57,000 square feet and is focusing on the expanding aerospace development in the Southeast US.
