Gas furnace ZeroFlow®

nitridingchamberfor the aerospace industry

Modern, energy-saving and ecological gas nitriding process used in HRN/VRN type furnaces ZeroFlow is a modern variant of controlled gas nitriding ensuring the maximization of process effectiveness and efficiency as well as economic efficiency, significantly exceeding the results of traditional solutions. It allows for precise shaping of any nitrided layer composition while maintaining minimal media consumption and post-process gas emissions, meeting the most stringent environmental protection regulations. This is especially important for mass production, where the benefits of ZeroFlow technology will be most significant.​ The uniqueness of the ZeroFlow technology lies in the fact that during the nitriding process, when the load does not absorb nitrogen from the atmosphere (e.g. during the reduction of nitrogen potential or in the diffusion phase), the introduction of ammonia into the furnace is completely stopped (zero flow) and the furnace remains tightly closed. This is a unique feature of the ZeroFlow technology and the horizontal type VR and plunge type PVR and automated process lines based on both previously mentioned types of furnaces dedicated to this technology. It enables the implementation of the most efficient nitriding processes, with minimum duration, energy and gas consumption, and post-process gas emission. Compared to traditional processes, ZeroFlow reduces the ammonia and nitrogen consumption many times as well as gas emissions to the environment (up to 10 times), and at the same time contributes to energy savings. It is a technology that protects the natural environment and supports sustainable development.
