Natural. Efficient. Engineered for Sustainable Thermal Management.
SED’s Spray Pond System is an advanced open-air cooling solution designed to efficiently lower process water temperatures through natural evaporation. By integrating modern materials, optimized nozzle design, and aerodynamic pond architecture, SED has redefined this century-old technology for today’s energy-conscious industries.
With over 200 systems successfully installed worldwide, SED’s spray ponds deliver reliable, low-cost, and environmentally friendly cooling - ideal for plants with open space availability or where mechanical cooling systems may not be feasible.
How It Works
Water Spraying
Warm water is pumped through specially designed nozzles, creating a uniform spray pattern over the pond surface.
Evaporative Cooling
Natural airflow and thermal updrafts enhance evaporation, dissipating heat from the fine mist droplets.
Heat Removal
The latent heat of vaporization cools the water, reducing its temperature close to the ambient wet-bulb temperature.
Water Collection & Reuse
The cooled water is collected in the pond and recirculated back to process equipment or condensers.
Energy Efficiency
The entire system operates without fans or compressors - driven solely by natural air movement for cooling.
Key Advantages
Energy-Efficient Cooling
Operates purely on natural convection, eliminating fan power and reducing overall energy costs.
Low Civil & Installation Cost
Simple construction with minimal infrastructure requirements makes it cost-effective to build and maintain.
Reliable and Low Maintenance
Optimized nozzles ensure clog-free operation and uniform spray distribution for consistent performance.
Water Conservation Design
Engineered for minimal drift losses and reduced evaporation beyond the pond area.
Scalable and Flexible
Adjustable spray flow rates accommodate variable cooling demands across different process loads.
