PRODUCT SHOWCASE: New 20 Bar Furnace Expands Vacuum Heat Treating Capabilities


Solar Atmospheres is using a new custom-built horizontal 20 bar vacuum furnace (40” wide x 50” deep x 36” high, 3500 max load) at its Hermitage facility. Designed and built by sister company Solar Manufacturing, it is the fastest cooling furnace in the Solar fleet.

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

The newly designed fan and improved gas-flow system minimizes pressure drops and increased gas velocities to nearly 200 MPH. State-of-the-art technology is incorporated throughout the furnace including an interactive touch screen SolarVac™ 4000 interface and a compact design. The furnace will be commissioned to process to stringent pyrometry specifications for aerospace customers.
