What is Ammonia Refrigeration?

Ammonia refrigeration is a process where ammonia (NH₃) is used as a refrigerant to absorb heat from a designated space and maintain lower temperatures. This cooling mechanism is not only energy-efficient but also environmentally friendly, making it an ideal choice for industries requiring constant temperature control, from food storage to pharmaceuticals.

Why is Ammonia the Superhero of Industrial Refrigeration Systems?

Ammonia refrigeration systems have been a cornerstone of industrial cooling for decades, offering unmatched energy efficiency, cost-effectiveness, and environmental friendliness. At Metro Refrigeration Industries, we specialize in delivering cutting-edge ammonia-based refrigeration systems tailored to meet the needs of a wide range of industries. In this comprehensive blog, we’ll cover the versatility and benefits of ammonia refrigeration, its diverse applications, and how Metro Refrigeration Industries plays a pivotal role in this field.

How Ammonia Works in Refrigeration

In an ammonia refrigeration system, ammonia gas absorbs heat in evaporators and is then compressed to a high-pressure liquid in ammonia compressors. It releases heat in the condenser and cycles back, continuing the cooling process. This efficient heat exchange system is at the heart of industrial refrigeration.

What is an Ammonia Refrigeration System?

An ammonia refrigeration system uses ammonia as a refrigerant in various cooling applications. These systems are vital in ensuring the safe and efficient cooling of goods in industries such as food storage, chemical processing, and pharmaceuticals.
