A modular air separation unit (ASU) is a compact process complex designed to produce pure industrial gases (oxygen, nitrogen, and argon) directly from atmospheric air using deep cooling (cryogenic separation) or pressure swing adsorption (PSA). The equipment is supplied as ready-to-use functional modules (blocks), mounted on rigid frames or inside special containers.

Purpose and Applications
The units are used to ensure an uninterrupted supply of high-purity industrial gases to enterprises.

Main applications:
Metallurgy: supplying oxygen for steelmaking and nitrogen for furnace purging.
Medicine: producing medical oxygen for life support systems.
Chemical and oil and gas industries: creating an inert atmosphere with nitrogen for fire and explosion safety.
Food industry: using nitrogen for packaging and storing food products.
Power and welding: providing gases for thermal cutting and welding processes.

Key benefits
Minimal installation: units are assembled and tested at the factory, reducing on-site construction work.
High mobility: the containerized design allows for easy relocation to new sites.
Economic independence: eliminating the need to purchase liquefied gas in cylinders and eliminating the costs of complex logistics.
Flexibility and scalability: the ability to quickly upgrade and increase capacity by adding new modules.
Full automation: processes are controlled remotely, eliminating the need for constant personnel presence.
