A large pumping group allows for rapid evacuation of the chamber and high operating vacuum levels.
The high power installed, the wide surfaces of the heating elements and the possibility to heat up the load with auxiliary convection at lower temperatures, allow fast and uniform heating ramps and shorter cycles.
A closed loop gas cooling system combines high flow capacity, high pressure and multidirectional gas flow distribution to guarantee a fast and uniform cooling of the load.
A variable frequency inverter allows for a fine regulation of the cooling speed.
A SCADA system provides comprehensive monitoring and control of the furnace and it includes OEE and performance measurement functions.
The furnace vessel remains at room temperature and can be installed in an air conditioned area without altering room temperature.
The system consumes electric energy only when needed and does not pollute air nor water.

The vessel develops along a horizontal axis and it is cambered at both ends.
The front door turns on solid hinges - from right to left - and opens to allow loading and unloading of the charge as well as inspection and maintenance of the thermal chamber.
The pumping group is interlocked and automatically sequenced to provide safe operation of its components.
The insulation of the thermal chamber is provided by rigid graphite boards covered by CFC that protect them from the flow of the cooling gas during quench.
The thermal chamber is placed on supports that allow easy extraction in case of maintenance operation.
The gas cooling system allows the cooling of the thermal chamber and of the load from operating temperature to room temperature.
It includes a centrifugal cooling fan, an asynchronous electric motor and a fin-and-tube heat exchanger.
