Batch-type furnaces for medium-high volume

The heavy-duty NX Pit-Type and NXH Front-Loading Gas Nitriding / Nitrocarburizing Furnaces provide flexibility for a wide range of applications. By incorporating multiple controlled heating zones, temperature uniformity inside the retort is +/-5°C (9°F) or better.

These furnaces are designed to have fast heat-up rates and a uniform temperature throughout the load. Optional internal cooling systems dramatically reduce cooling times, shortening total cycle time and maximizing furnace usage.

MAIN FEATURES

  • Inconel 600 (refractory steel) retort and racking for long service life and inactivity with regard to the nitriding atmosphere.
  • Uniform temperature distribution, obtained through independently controlled heating zones and intensive atmosphere circulation ensuring full control of nitriding potential in all stages of the process.
  • Light ceramic fiber insulation, reducing heat losses and thus energy consumption.
     
  • Kanthal long lasting heating elements.
  • Integrated cooling systems.
     
  • Larger furnaces may be equipped with a 'Turbo' cooler, for accelerated cooling of the load. This option is used where productivity is a major issue.
     
  • Some pit-type furnaces may be equipped with a vacuum purging system. This option significantly accelerates exchange of atmosphere in the retort and is very useful in nitriding of stainless steels.
