Heat treatment specialist Solar Atmospheres of Western, PA, USA, will soon welcome a custom-built horizontal 20 bar vacuum furnace to its Hermitage facility. Designed and built by sister company Solar Manufacturing, this new furnace measures 40” wide x 50” deep x 36” high and is the fastest cooling furnace in the Solar fleet and one of only a few of its kind in the USA.

The excessive pressure and high speed gas velocities of the 20 bar furnace simulate the benefits of oil quenching, but using inert gas as an alternative to oil minimise distortion and provides a much cleaner and greener process. Solar can also better serve customers requiring vacuum carburising by increasing core hardnesses of large cross-sections. This a particular benefit to those in the gear industry.

President Bob Hill stated, “By adding these unique capabilities of the 20 bar to our resources, we can now effectively process a wider range of materials and assist more customers than we could with our 10 bar furnaces.”

The high-tech furnace was designed with many innovative features to improve cost-efficiency and results, including an improved gas-flow system to minimise pressure drops and a radial heat exchange. State-of-the-technology is incorporated throughout including an interactive touch screen interface and a compact design.
