Dissociated Ammonia Generator

About Dissociated Ammonia Generator

Dissociated Ammonia Generator manufactured by United Enterprises is a specialty atmosphere generator that dissociates ammonia into a 75% H / 25% N mixture for industrial heat treatment, brazing, sintering and jewellery applications.

Brief Description:

Dissociated ammonia gas is the practical, economical route to a clean reducing atmosphere where bottled hydrogen is impractical or too costly. Our Dissociated Ammonia Generators use a nickel catalyst at high temperature to dissociate NH into its hydrogen and nitrogen components.

Built with high-quality reaction retorts, nickel catalyst beds, water-cooled coolers and PSA / molecular-sieve dryers, our generators deliver capacities from 5 Nm/hr to 100+ Nm/hr with PLC / SCADA-based control and low residual NH.

Each unit is engineered around the customers furnace size and atmosphere quality target.

Characteristics:

• Dissociates NH into 75% H / 25% N
• Capacity from 5 Nm/hr to 100+ Nm/hr
• Nickel catalyst at 900C1000C
• Water-cooled cooler with PSA / molecular-sieve dryer
• Low residual NH (<25 ppm achievable)
• PLC and SCADA-based control
• Suitable for bright annealing, brazing, sintering
• Robust industrial-duty construction

About United Enterprises:

United Enterprises is a recognised Dissociated Ammonia Generator manufacturer in India with over 25+ years of experience in atmosphere generators. We design, manufacture, supply, export and commission tailor-made dissociated ammonia generators across Asia and Europe. Our turnkey approach, in-house design and CE / ISO compliant manufacturing support SS pipe, copper, jewellery and PM industries.

FAQs:

Q: Why dissociated ammonia instead of pure hydrogen?

A: Lower storage cost, easier transport and safer handling than bottled hydrogen at the cost of slight nitrogen content.

Q: Suitable for all bright annealing?

A: Yes for most SS, copper and PM bright annealing. For premium mirror-finish applications, pure hydrogen may be preferred.

Q: Do you offer pure hydrogen versions?

A: Yes. Pure hydrogen can be generated by an additional Pd-membrane purification stage or by water electrolysis.

Reliable Gas Supply for Heat Treatment and Inert Atmospheres

This ammonia cracker is ideal for processes requiring a controlled atmosphere, such as annealing, sintering, and heat treatment furnaces. Its adjustable pressure and high-purity output support efficient and repeatable results for demanding industrial applications.


Efficient Operation with Simplified Maintenance

Thanks to its automatic PLC-based control system and robust nickel catalyst design, the generator provides stable gas production with low maintenance demands. Periodic checking is sufficient, reducing downtime and operation costs for busy industrial environments.


Integrated Safety and Environmental Compliance

User safety is prioritized through in-built interlocks, alarm systems, and a standard venting and scrubbing exhaust setup. Meeting international emission standards, this generator ensures both operator protection and ecological responsibility.
