A practical breakdown of chamber dimensions, part fit, and processing capacity in standard ION HEAT plasma nitriders.


In plasma nitriding operations, chamber size plays a central role in both technical planning and cost efficiency. It affects load configuration, cycle duration, thermal stability, and energy usage across every batch.


To address these operational challenges, ION HEAT has developed a product line with four standard plasma nitriding furnace sizes. Each model is based on a hot wall design and covers a wide range of industrial needs, combining the efficiency of standardized equipment with the flexibility for customization.

This illustration shows the relative working dimensions—diameter and height—of ION HEAT's standard hot wall vacuum chambers.

Working Volume: The Measurement That Actually Matters


The comparison chart focuses on the usable inner volume—that is, the interior of the vacuum vessel where the parts are loaded and the nitriding process takes place.

Why Plasma Nitriding Furnace Sizes Matter in Performance and Productivity


Choosing the right chamber size helps optimize:

  • The number of parts per load

  • Fixture design and part positioning

  • Thermal distribution during the cycle

  • Energy efficiency across the batch

  • Nitriding uniformity, especially for complex geometries or heavy-duty loads


Each ION HEAT plasma nitrider includes multi-zone heating, precise multi-channel temperature control, top-injection gas systems for uniform distribution, and forced-air cooling for improved thermal stability.


What If Your Parts Don’t Fit These Dimensions?


That’s where our engineering team steps in. ION HEAT can deliver fully customized plasma nitriders, adapting vessel dimensions, thermal design, heating elements, gas flow systems, and safety configurations to match your production requirements.This comparison doesn’t set limits. It helps dimension the process correctly—so that each company can make an informed investment in its plasma nitriding furnace setup.
