Ammonia refrigeration is one of the older types of refrigeration that is still used today. While the average person doesn't realize it, just about all food and drinks that are purchased have been kept cold using ammonia refrigeration at some point along the way. This is because it is a reliable and efficient refrigerant with years of safe, proven utility.

A core component of the HVAC system, a chiller cools the water or brine used to cool and dehumidify air in buildings or industrial processes. It's a factory-assembled unit that cools the water or brine using an evaporator and has an internal or a remote condenser with appropriate controls. The condenser can be either water-cooled or air-cooled. A chiller based on such a design has a variety of applications, from space cooling to process purposes.
