A number of the systems created at the enterprises of special mechanical engineering, for example, cryogenic air separation units, complexes for the liquefaction of natural gas, require automatic armature. It is developed for these and other systems by enterprise «Arkon» taking into account the special conditions of application. The main features of such armature are considered. Examples of the application created armature in the unit the expander-compressor, cold gasificator, production unit of electrolysis hydrogen and oxygen are resulted.
