Vacuum Hardening Furnaces
Our vacuum furnaces can fulfill the most demanding gas quenching thanks to the rotating cooling system ensuring an excellent cooling uniformity and thanks to the high gas quenching pressure. An automatic process guarantees the perfect reproducibility of the result.

Vacuum Tempering and Allnit® Nitriding - Nitrocarburizing Furnaces
Allnit® is a thermochemical nitriding and nitrocarburizing heat treatment hardening the steel surface at low pressure within a vacuum furnace.

Process Advantages:
- Control of the Layers’ Metallurgy
- Compact Combination (White) Layer
- No Surface Oxidation
- Homogeneity of the Nitriding or Nitrocarburizing for:
         - Tubes Inner Surfaces, Holes, Cavities
         - Bulk Parts
- Cleanliness of Parts after Nitriding or Nitrocarburizing
- Ecological friendly

Atmosphere Controlled Furnace
Our atmosphere controlled and sealed quenching furnaces are automatically controlled by PLC. They are suitable for different heat treatments: carburizing, carbonitriding, oil quenching, annealing and normalizing of parts made by carbon steels, low alloy steel and cast iron.
