Dry Cooler with Wet Pad / Adiabatic Cooler

Dry Cooler with Wet Pad / Adiabatic Cooler

A dry cooler with a wet pad, also known as an adiabatic cooler, combines the features of a dry cooler and an evaporative cooler. The wet pad, often made of fibrous material or cellulose, is wetted with water, and air is drawn through it, causing water to evaporate and cool the air. This pre-cooled air then passes through the dry cooler's heat exchanger, further enhancing its cooling capacity.

Dry Cooler:

A dry cooler uses ambient air to cool a fluid, typically without direct water contact. It rejects heat directly to the atmosphere.

Wet Pad (Evaporative Cooling):

The wet pad utilizes the evaporation of water to cool the air. As water evaporates, it absorbs heat from the surrounding air, lowering the air's temperature.

Combined Cooling:

In a dry cooler with a wet pad, the wet pad pre-cools the air before it enters the dry cooler's heat exchanger. This pre-cooling enhances the overall cooling capacity of the system.

Benefits:

Increased Efficiency: The wet pad can improve cooling efficiency, especially in hot and dry climates.

Energy Savings: Compared to traditional mechanical cooling systems, evaporative cooling can be more energy-efficient.

Reduced Water Consumption: The system uses a small amount of water for pre-cooling, unlike traditional wet cooling towers.

Applications:

High Ambient Temperatures: Dry coolers with wet pads are well-suited for environments with high ambient temperatures.

Energy-efficient Solutions: They are suitable for applications where energy savings are a priority.

Industries: They are used in various industries, including factories, warehouses, and data centers.
