Ammonia (NH3) Refrigeration: Advantages & Safety Considerations

Ammonia's thermophysical properties make it extremely efficient in large-scale refrigeration, offering lower mass flow rates and smaller heat exchangers for equivalent duty.

Safety considerations include gas detection, ventilation, relief systems and trained personnel. Modern standards and engineered controls mitigate risk when systems are correctly designed and maintained.

Owners should evaluate lifecycle costs — ammonia systems can be very economical where safety and regulatory requirements are met.
