Poultry House Evaporative Air Cooler

The Poultry House Evaporative Air Cooler combines wetted cooling media, a water circulation system and a fan to supply fresh air to a poultry building. It can be considered for farms that need equipment-based air delivery at selected locations within a coordinated ventilation design.

For commercial broiler and layer houses, cooler quantity and placement are planned around building dimensions, bird distribution, air inlets and exhaust capacity. The objective is to deliver useful airflow while managing humidity and avoiding excessive drafts at bird level.

The cooler can be incorporated into a new agricultural project or assessed for a suitable existing steel structure building. Mounting supports, wall openings, water supply, drainage and electrical connections should be coordinated with the poultry house construction drawings.

Evaporative cooling performance depends on outdoor temperature and humidity. Equipment selection and operating controls should therefore be designed according to local climate and farm conditions.

1. Supplies outdoor air through wetted evaporative media.
2. Combines air movement and cooling within a compact equipment arrangement.
3. Can be positioned to suit poultry house airflow and access requirements.
4. Works with a properly designed exhaust or air-relief arrangement.
5. Cooler quantity and discharge direction can be planned for different building layouts.
6. Accessible media and water components support routine inspection and cleaning.
7. Cabinet and mounting materials can be selected for the farm environment.
8. Control options can be coordinated with compatible poultry ventilation equipment.
9. Supports project-specific planning for commercial farms and agricultural contractors.

• Cabinet and support frame: Enclose and support the cooler components.
• Evaporative cooling media: Provide the wetted surface through which outdoor air passes.
• Fan and motor: Move air through the media and into the planned supply path.
• Water distribution assembly: Delivers water across the cooling media.
• Water collection and drainage: Collect excess water and allow scheduled cleaning.
• Discharge opening or connection: Directs supply air toward the building or a specified air passage.
• Electrical and control components: Operate the fan and water circuit according to the selected configuration.

Water is distributed over the cooling media while the fan draws outdoor air through it. As some of the water evaporates, the incoming air loses sensible heat and gains moisture.

The fan supplies this air through the selected discharge arrangement. Exhaust fans or designed relief openings move air out of the poultry house, allowing fresh air to continue entering as part of the livestock ventilation system.

Cooling results vary with outdoor humidity, airflow and water distribution. Bird-level air speed, indoor humidity and ventilation rate must be considered together when the cooler is integrated into a poultry house.

• Cooling media and service-access arrangement.
• Air discharge orientation and connection details.
• Mounting brackets and structural supports.
• Water supply, overflow and drainage provisions.
• Compatible temperature-based and ventilation control arrangements.

Installation: Review the poultry house dimensions, bird type and occupancy, local weather data, existing fans and intended airflow path. Confirm that the wall or supporting steel structure can carry the equipment and provide safe access for servicing. Install the cooler at the designed location, seal the building opening and connect the specified water supply, drain and electrical protection. Commission the system by checking media wetting, drainage, fan operation and airflow at bird level.

Maintenance: Inspect cooling media, water distribution openings, the pump, collection area and drain at intervals suited to water quality and farm dust levels. Remove mineral deposits and debris, check for leaks and replace damaged media when required. Keep intake areas clear and follow the farm’s cleaning and biosecurity procedures. Isolate power before inspecting electrical or rotating components.

Illustrative broiler house scenario: An agricultural engineering contractor assesses cooler locations along a commercial broiler building. Equipment supports, supply airflow and exhaust operation are specified together to suit the house layout and bird-level conditions.

Illustrative layer farm scenario: A multi-house farm reviews evaporative air coolers for buildings with different dimensions and ventilation arrangements. Each house receives a separate equipment and control proposal based on its airflow requirements and available utilities.

1. How is the required number of coolers determined?
It depends on house dimensions, ventilation targets, cooler airflow and the planned air distribution pattern.

2. Can a cooler be used in a broiler or layer house?
Yes, subject to a design that accounts for the birds, housing layout and ventilation strategy.

3. Does it replace poultry house exhaust fans?
No. Exhaust or relief airflow must be considered as part of the complete ventilation design.

4. How does outdoor humidity affect cooling?
Evaporative cooling generally provides less temperature reduction when outdoor air is more humid.

5. Can it be installed on an existing building?
A retrofit is possible when the structure, available space, utilities and airflow arrangement are suitable.

6. Can the cooler connect to farm controls?
Compatible control options can be reviewed according to project requirements.

7. What information is needed for a quotation?
Provide building drawings, farm location, poultry type, ventilation details and available water and electrical supplies.

8. What maintenance does the water circuit require?
Regular inspection, cleaning and drainage help manage debris and mineral buildup; the schedule depends on water quality and use.

9. How are drafts near birds avoided?
Equipment placement, discharge direction and fan operation are selected with bird-level air velocity in mind.
