AHUs (Air Handling Units)

Air Handling Units are integral components of AHU emergency cooling systems. They regulate the airflow and temperature within the building by circulating and conditioning the air. AHUs ensure that the cooled air is evenly distributed throughout the space, creating a comfortable environment for occupants and protecting equipment from overheating.


Chillers are responsible for cooling the water or refrigerant that flows through the AHU system. These units remove heat from the water or refrigerant, thus cooling it down to the desired temperature. Chillers are available in various types, including air-cooled and water-cooled options, depending on the specific needs of the facility.


Pumps circulate the chilled water or refrigerant from the chiller to the AHUs and back. They ensure a consistent flow of the cooling medium through the system, enabling efficient heat exchange and maintaining the desired temperature levels. Pumps are crucial in ensuring the proper functioning of AHU emergency cooling systems.

Cooling Towers

Cooling towers work in conjunction with the chillers to dissipate heat from the cooling medium. They transfer the heat from the water or refrigerant to the surrounding environment, allowing it to cool down and be recirculated back into the AHU system. Cooling towers are essential for maintaining the overall efficiency and effectiveness of the cooling process.

Control Systems

Control systems provide the intelligence behind AHU emergency cooling systems. They monitor and regulate the operation of various components, ensuring optimal performance and energy efficiency.
