Livestock Evaporative Air Cooler

The Livestock Evaporative Air Cooler supplies fresh air through water-wetted cooling media. As water evaporates, it absorbs heat from the incoming air before that air is delivered to the livestock building.

For commercial pig houses and poultry facilities, the cooler is specified as part of a livestock ventilation system. Air supply, exhaust capacity, distribution and humidity management must be planned together to support suitable housing conditions during hot weather.

The equipment can be considered for new pig farm construction or for upgrades to an existing agricultural building. Its mounting and air outlet arrangement are selected to suit the building envelope, including a steel structure building where structural support and weather protection are addressed in the design.

For farm operators, engineering companies and project buyers, the final configuration is designed according to local climate and farm conditions. Cooling results vary with outdoor temperature, humidity, airflow and building operation.

The water distribution assembly wets the evaporative media. A fan draws warm outdoor air through the media, where part of the water evaporates and removes heat from the passing air.

The unit delivers the treated air through its selected outlet or duct connection. The building must also have an appropriate exhaust path so that heat, moisture and used air can leave the animal space.

Evaporative cooling is affected by outdoor humidity. During humid conditions, the available temperature reduction may be smaller, making ventilation design and operational control especially important.

Installation planning: Confirm the outdoor-air intake position, supply route, exhaust capacity, access for servicing, water source, drainage and electrical supply. Locate the intake away from avoidable dust or contaminated exhaust. For installation on a steel structure building, have the project engineer verify support loads, fixing details and weather sealing before mounting.

Commissioning: Check fan rotation, water flow across the media, drainage, controls and the balance between supplied and exhausted air. Confirm that airflow reaches the intended animal zones without creating unsuitable drafts.

Routine maintenance: Inspect and clean the intake and cooling media as required by site conditions. Check the pump, water distribution points, reservoir or drain, fan and electrical connections. Follow the selected equipment manual for cleaning, media replacement and seasonal shutdown to reduce scale, blockage and standing water.

Illustrative pig farm project: For a new commercial pig house, an engineering team may position evaporative air coolers at planned fresh-air intake points and coordinate their operation with exhaust fans. Unit selection would follow the house dimensions, stocking plan and local summer conditions.

Illustrative poultry project: For a poultry building, the cooler quantity and air distribution route may be designed alongside existing ventilation equipment, with attention to bird-level airflow and indoor humidity.

Illustrative renovation project: An agricultural project buyer upgrading a steel structure building may specify mounting frames, water connections and service access around the existing structure.
