PSA Nitrogen Generators for Heat Treatment Processes

Heat treatment — the process of enhancing the surface hardness of metals and alloys — is designed to impart long service life and mechanical strength to the material. Nitriding, applied as part of this process, enables controlled nitrogen diffusion into the surface, making it easier to achieve high hardness and superior wear resistance.

Oxyvital PSA nitrogen generators are purpose-built to meet exactly these demands, delivering a meaningful contribution to industrial processes. By producing nitrogen on-site within the facility, they eliminate external supply dependency, enhance process safety, and provide a sustainable cost advantage throughout the heat treatment process.

Continuous Operation

Systems are designed to deliver uninterrupted production 24/7. Sudden gas outages or supply disruptions are eliminated. Operational reliability is significantly enhanced in high-volume production facilities.

Modular and Scalable Architecture

Additional modules can be integrated into the system as capacity requirements grow. Investment planning can be carried out incrementally. As operations scale, gas production capacity can be expanded in parallel.

Safety Advantage

Eliminates the hazards associated with high-pressure cylinders and cryogenic tanks. Since nitrogen gas produced by the generator is non-flammable, the risk of fire and explosion is significantly reduced.

Environmental Management Contribution

Reduces the need for transportation and cryogenic production processes. Lowers energy consumption and carbon footprint. Enables a more sustainable production model.

Why Use a Nitrogen Generator in the Heat Treatment Industry?

Unlike conventional liquid nitrogen tanks or high-pressure cylinder gases, traditional supply methods introduce significant disadvantages — including high costs, logistical dependency, storage requirements, and safety risks. PSA nitrogen generators eliminate these challenges by enabling continuous, controlled on-site nitrogen production. They also play an active role at multiple stages:

Inert Protection

At elevated temperatures, a low-oxygen environment is required to prevent oxidation and undesirable reactions on metal surfaces. High-purity nitrogen creates an inert atmosphere that preserves surface quality.

Quenching Atmosphere

In certain applications, controlled cooling of the metal is required. In this context, generators provide a safe cooling atmosphere without inducing oxidation, helping to preserve the metallurgical properties.

Atmosphere Control

In specialized heat treatment processes, precise adjustment of the in-furnace gas composition is essential. Nitrogen generators supply gas at the required purity and flow rate, facilitating accurate process control.

Annealing Protection

During annealing, nitrogen protects the metal surface against oxidation and undesirable chemical reactions. This ensures that stress relief is achieved effectively and that the targeted microstructure is obtained.

Benefits of PSA Nitrogen Generators in Heat Treatment Processes

✓

Nitrogen gas is used in many applications as the primary carrier atmosphere gas for the controlled delivery of reactive gases.

✓

As a carrier gas, nitrogen enables the controlled transport of reactive gases in processes such as carburizing, nitriding, and carbonitriding.

✓

Its inert properties help displace oxygen from flammable gas mixtures, enhancing safety.

✓

In its role as a protective atmosphere, it prevents the formation of oxide layers on surfaces — particularly during annealing and sintering operations.
