NH3 Cracker

About NH3 Cracker

NH Cracker manufactured by United Enterprises is a specialty atmosphere generator that cracks anhydrous ammonia into a clean 75% H / 25% N atmosphere for industrial heat treatment, brazing and jewellery applications.

Brief Description:

NH Crackers offer a cost-effective alternative to bottled hydrogen, particularly for shops with high atmosphere demand. The cracker uses a nickel catalyst at high temperature to dissociate NH into H and N.

Our NH Crackers are built with high-quality reaction retorts, nickel catalyst beds, water-cooled coolers and PSA / molecular-sieve dryers for low residual NH. Capacities from 5 Nm/hr to 100+ Nm/hr are supplied with PLC / SCADA-based control.

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

Characteristics:

• Cracks 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

We design, manufacture, supply, export and commission tailor-made NH crackers 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: NH Cracker vs Ammonia Cracker same?

A: Yes. NH Cracker, Ammonia Cracker and Ammonia Dissociator all refer to the same equipment.

Q: How is residual NH measured?

A: Through inline NH analysers and periodic lab analysis.

Q: Can I add a purifier later?

A: Yes. Pd-catalyst purifiers and additional drying can be added for ultra-low residual NH.

Efficient Hydrogen Generation

The NH3 Cracker utilizes a nickel-based catalyst to dissociate anhydrous ammonia at elevated temperatures (700C-850C), producing a continuous supply of hydrogen-rich gas. Designed for on-site generation, it eliminates the need for stored hydrogen cylinders, enhancing safety and operational efficiency. The compact, automatic system ensures reliable output with low maintenance needs.


Flexible Design & Accessories

Offered as skid-mounted or floor-standing units, the cracker can be tailored to client space and output requirements, with customizable feeding size and dimensions. Optional accessories like an ammonia dryer, purifier unit, and gas analyzer further enhance output purity and process control, while safety features like flame arrestors and pressure relief valves ensure secure operation.


Certified Quality & Application Versatility

Built to CE and ISO certification standards, this system is suited for a variety of industrial processes such as heat treatment, brazing, annealing, and powder metallurgy. Its durable construction, high dew point performance (down to -60C with a dryer), and automatic PLC-based control make it a reliable and high-performance solution for demanding applications.
