Adiabatic Type Air Cooler

Hot liquid material enters the coil inlet, shown in red. Heat from the process fluid is dissipated across the coil surfaces and transferred to the fins. The air humidification pre-cooling system consists of an evaporative wet curtain located on the side of the coil to thoroughly moisten. Ambient air is drawn into the unit by a ventilator located at the top. And flow through the evaporative wet curtain plate. As the air passes through the evaporative wet curtain, the humidity increases and the dry bulb temperature decreases (only a few degrees of temperature difference from the wet bulb). After that, the pre-cooled air flows over the surfaces of the coils and fins, and the heat removal capacity of the unit is significantly improved. The heat of the process fluid is transferred to the air. and then released into the atmosphere. The cooled liquid flows out of the unit through the coil outlet. As shown in blue.
