Large Scale Livestock Evaporative Cooling System

The Large Scale Livestock Evaporative Cooling System combines cooling pad sections, water circulation and planned ventilation to treat incoming air across a livestock building. Warm outdoor air passes through wetted pads, where evaporation absorbs heat before the air enters the animal space.

For commercial pig farms and poultry houses, the pad wall is designed together with exhaust fans, air inlets and controls. Their placement and capacity determine how air travels through the building and how moisture is removed.

The system can be planned for new pig farm construction or a suitable ventilation upgrade. Modular pad sections allow the intake area and supporting frame to follow the wall openings and building layout, including those of a steel structure building.

For livestock groups, engineering companies, distributors and agricultural project buyers, the final design depends on animal type, stocking plan, local climate, water quality and the required ventilation rate. Cooling performance must be assessed for the project rather than assumed from a fixed temperature-reduction figure.

The pump supplies water to the distribution line above the cooling pads. Water flows over the media, while any unevaporated water is collected according to the specified water-circuit design.

Exhaust fans draw warm outdoor air through the wetted pads. As part of the water evaporates, it absorbs heat from the passing air. The treated air then travels through the livestock house toward the exhaust points.

Evaporation also adds moisture to the incoming air. The available cooling effect depends on outdoor temperature and relative humidity, while suitable fan capacity and air distribution remain essential throughout the building.

Project planning: Confirm building drawings, animal numbers, local climate data, ventilation targets, water quality and electrical supply. Coordinate the pad wall with exhaust fan positions and the intended airflow path. For a steel structure building, verify opening details, support loads, weather protection and maintenance access with the project engineer.

Installation and commissioning: Mount the frames, fit the pad sections and connect the water distribution, collection and drainage components. Test even wetting across the pad surface, check for leaks and confirm that fan operation draws air through the intended intake area.

Routine maintenance: Inspect pads for blockage, damage or uneven wetting. Clean the water circuit, pump inlet, gutter and drain as required by site conditions. Monitor scale and algae, manage water replacement according to water quality, and follow the selected media and equipment manuals when cleaning or replacing components.

Illustrative commercial pig farm: A new pig house is planned with modular pad sections at the fresh-air intake and exhaust fans at the opposite end. The engineering team sizes both sides of the ventilation system to the building and stocking plan.

Illustrative poultry project: Several poultry houses share a project specification but receive individual pad wall lengths and fan selections according to each building's dimensions and ventilation needs.
