DAMAC Edgnex Data Center – Riyadh

PreCooll utilizes the natural principle of water evaporation to create a

cooling effect. The system is installed around air-cooled chillers to precool the ambient air before it enters the condenser.

How It Works:

Hot ambient air approaches the cooling system, Water is distributed over the Oxyvap® pads, Air passes through the wet pads, causing water evaporation, Evaporation absorbs heat, cooling the air by up to 25°C, Cooled air enters the condenser, improving efficiency
