All You Need to Know About Commercial Ammonia Chillers

Commercial ammonia chillers are a reliable and efficient cooling solution for a variety of industries and applications. As a result, they are becoming an increasingly popular option for businesses looking to reduce their energy consumption and overall costs. In this blog post, we will explore the different uses of commercial ammonia chillers, as well as their advantages and disadvantages.

What is an ammonia chiller?

An ammonia chiller is an industrial cooling system that uses a combination of liquid ammonia and a compressor to reduce the temperature of a large area or space. Ammonia chillers are becoming increasingly popular in industrial applications due to their ability to provide efficient and effective cooling while also being environmentally friendly. They are often used in places where traditional cooling methods, such as air conditioning, would be impractical or too costly. Commercial ammonia chillers are also quieter than other cooling systems and can be installed quickly and easily.

How does a commercial ammonia chiller work?

In many cases, commercial ammonia chillers use a closed-loop system of water and refrigerant, typically ammonia. The ammonia is compressed and then cooled as it passes through condenser coils that are cooled by either an evaporative condenser or an air-cooled condenser. As the ammonia travels through the condenser, heat is released which cools the water that is passing through the evaporator coil inside the chiller.

The cooled water is then sent to the equipment or process being cooled. The process of cooling continues in a loop, as the heated water returns to the evaporator where it is re-cooled and sent back out to be used again. This cycle helps maintain a steady temperature while keeping energy costs low.

Because the refrigerant is always contained within a closed loop, there is no need to vent gases into the atmosphere, making commercial ammonia chillers an environmentally-friendly choice. 

In addition to their efficient design, commercial ammonia chillers are also extremely durable, with a long lifespan when properly maintained. Furthermore, they can also be easily adjusted to meet the needs of specific processes and applications in various industrial or commercial settings.

Applications for commercial ammonia chillers

Commercial ammonia chillers are commonly used in food processing, beverages, HVAC systems, laboratories, data centers, and other applications that require a reliable source of cooling. They are an ideal choice for large-scale industrial processes or commercial settings that require large amounts of cooling, as they are designed to be robust and efficient.

Ammonia chillers are used in the food and beverage sector to cool materials, establish the ideal temperature for food preparation and storage, and preserve the quality and shelf life of goods. Dairy products, fruits and vegetables, meats, and other food products can be refrigerated using ammonia chillers throughout their processing in order to keep them cold and safe to consume.

Moreover, ammonia chillers are employed in HVAC systems to provide cooling during heat waves and provide year-round comfort. Commercial ammonia chillers are also frequently used in data centers to maintain server temperatures at ideal levels and avoid overheating or system failure. They can be used in laboratories to keep delicate products that require continual refrigeration at particular temperatures, such as reagents, vaccines, and pharmaceuticals.

Special considerations for operating ammonia chillers

When operating a commercial ammonia chiller, there are a few considerations to keep in mind. First, proper maintenance and operation are essential for safe operation of the chiller and avoiding any potential risks. A qualified service technician should be consulted for regular maintenance of the chiller and safety checks.

In addition, it is important to have a qualified technician evaluate the system regularly to check for any changes in performance or pressure levels. This will help ensure that the system is running efficiently and safely. It is also important to maintain the correct levels of refrigerant and that the system is properly vented and insulated. If not, then ammonia vapor can escape and pose a serious hazard. Additionally, it is important to follow all local regulations regarding use of the chiller.

By taking these steps, businesses can safely operate their commercial ammonia chillers and maximize their efficiency.


Commercial ammonia chillers are an effective and efficient way to cool large spaces and areas. They are most often used in industrial and commercial settings, such as food processing plants, warehouses, and cold storage units. While there are some special considerations when operating a commercial ammonia chiller, their use is generally safe and reliable. A commercial ammonia chiller can deliver dependable cooling services for many years to come as long as the correct safety procedures and maintenance practices are followed.
