An evaporator unit is a component of an air conditioning or refrigeration system that removes heat from the air or liquid to be cooled by evaporating a refrigerant inside a coil. Evaporator units are critical to the performance and efficiency of cooling systems and can be designed for various applications such as residential,commercial, and industrial cooling.

They work by drawing warm air or liquid over the evaporator coil, which absorbs the heat and turns the refrigerant into a gas. The cooled air or liquid is then circulated back into the space to be cooled, while the refrigerant gas is sent to the compressor for further processing. Evaporator units come in different types, including air-cooled, water-cooled, and direct expansion (DX) systems. Proper maintenance and cleaning of the evaporator unit is important to ensure optimal performance and prevent breakdowns.
