Production Series Vacuum Furnace

About me


Production Series Vacuum Furnace set the pace for high productivity.

If greater size and load capacity are what you need, the Global Vacuum Series high-temperature, high vacuum furnaces will satisfy your heat-treating requirements.

The oversized all-stainless steel chamber allows you to temper, harden, stress relieve, austenitize, anneal, sinter bond, braze and perform many other custom heat treating processes on large loads. These high vacuum furnaces come with many standard features such as our three-zone heat control and electro- pneumatically operated Heat Pack door shield assembly, creating a precision heating environment is created for perfect temperature uniformity.

Equipped with a unique high-speed pumping system, the vacuum furnaces quickly reach high-vacuum for maximum processing time. Even cool downs are fast and efficient, as the comes standard with a 25 HP inert gas Quick Cool System, in order to rapidly, yet precisely cool the chamber and ready it for the next load.

The high vacuum furnaces have automatic control system that requires no operator to monitor the process. The vacuum furnaces are fully contained units with no exposed wires, cables, or pumps, allowing for quick and easy installation in your facility. The Production Series is assembled when it reaches your plant, and attaching basic utilities is all that is necessary. With a removable Hot Zone, the minimal maintenance is simple and fast.

System Controls for Production Series Vacuum Furnace

The system has state-of-the-art full computer control as standard, enabling automatic control of all system functions. System operation is defined by user created recipes which are stored on the system. More than 30 user friendly screens display all set points and operating data. Process parameter can be accessed and stored on the system in real time for historical reference or as customer required documentation. Operating parameters are displayed on the system 17 ̎ flat panel touch screen for the operator’s ready reference. Full data logging with print capability out is standard.
