The Cristal range is made of furnaces dedicated to heat treating under vacuum at high temperatures. The enclosure is insulated with specific metals, with a possible choice of molybdenum or tungsten resistors. It is the perfect tool for clean treatments at high temperature. Its design allows precise positioning of loads. The patented resistor design ensures exceptional precision while piloting your process.

The Cristal range allows to treat pieces under vacuum with a wide range of working temperatures. Indeed, depending on the selected heating elements, working temperatures allow heating up to 2300°C.


In addition to this, Cristal furnaces are adapted to a large scope of applications and provided with clean treatments, at high temperatures. Loading is simplified by an easy access to the hearth, and ensures a precise positioning of parts.
The best treating conditions are then gathered.
