Liquid Nitrogen Production Line

The series of machine set is available for preheating in air furnace, salt bath nitriding, and oxidizing salt bath, in particular for low toxic and environment-friend QPQ treatment. QPQ process is a multi step process that provides a very uniform consistent nitride layer on your components.
Current systems have evolved into complete process lines to perform salt bath nitriding from start to finish.
