Compact C669 Vacuum Furnace with Gas Cooling System

Durable graphite insulation and heating elements provide long, reliable service in this heavy-duty furnace designed for the industrial workplace. The pumping system, power supply and cooling systems are generously sized to enable a wide range of industrial heat treatment applications including quench hardening and tempering, degassing, annealing, etc. The cooling gas re-circulation system includes a multi-nozzle gas feed arrangement to optimize the uniformity and rate of cooling of the load during quenching.

The furnace is completely assembled, leak tested, and then dismantled as required for shipment. The system will be ready for operation after re-assembly, interconnection of subsystems and connection to power, water and atmosphere supply lines in the PURCHASER’s plant.
