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
The DAMAC EDGNEX data center in Riyadh represents a critical infrastructure investment supporting Saudi Arabia's Vision 2030 digital transformation goals. The facility operates in extreme desert conditions, requiring innovative cooling solutions.
