Nitrogen Generation for Heat Treating

Heat Treating

Kilns and furnaces used for heat treating may be under pressure; that classifies them as autoclaves that require a greater volume of N2 gas. Kilns and furnaces may also be used as a melting device. All of these processes can utilize a nitrogen generator to combat their one enemy – oxygen. O2 discolors the product, and can dangerously weaken it. Any metal over 600° F will oxidize in the presence of O2. The purity for most metal applications is at most 99.99%; pressure 30-100 PSIG. Most are purge and fill nitrogen applications that can be accommodated with larger or multiple N2 surge tanks instead of pressure-boosting compressors.
