Wetted Pad Surface
Pad depth, height, width, flute geometry and water distribution affect air resistance and contact time.
For poultry houses that need an evaporative cooling and negative-pressure ventilation route matched to local climate and house layout.
Poultry-House Climate Control
The OVOWELL poultry cooling pad and exhaust fan system combines evaporative cooling surfaces with controlled air movement for poultry houses. A useful design starts with house dimensions, climate, bird density, target airflow, static pressure and the available power and water services. Final cooling performance depends on the complete air path and the site conditions, not on one pad or fan specification alone.
Water wets the pad media while exhaust fans draw outside air through the wetted surface. Part of the water evaporates, and the incoming air can become cooler and more humid before it enters the house. The useful result depends on the difference between dry-bulb and wet-bulb conditions, airflow, pad selection, house leakage and heat load.
Pad depth, height, width, flute geometry and water distribution affect air resistance and contact time.
Exhaust fans create the air path through the pad and across the house, subject to inlets, openings and leakage.
Dry-bulb temperature, wet-bulb temperature and humidity determine the available evaporative cooling margin.
Bird density, house structure, solar gain, equipment and target air speed all influence the required ventilation duty.
The pad is not selected by a catalogue code alone. It must fit the air volume, pressure loss, available wall opening, water loop and service access of the house.
Choose height, width, thickness and flute arrangement for the planned opening and air path.
Confirm the final panel dimensions, quantity and replacement format.
Provide a pump, basin, pipework and control route that wets the pad evenly without uncontrolled overflow.
Confirm water quality, filtration, bleed-off and cleaning access.
Frame material and deep-water basin options are reviewed against corrosion exposure, wall construction and service access.
Confirm the approved material and connection details for the ordered system.
Pad thickness and wet condition add pressure loss to the system.
Match the pad selection to the fan duty and the house static-pressure target.
Exhaust fans complete the design. Fan type, opening size, shutter arrangement, motor, control and installation position must be reviewed with the pad and the house envelope.
Heavy-hammer, push-pull, shutter and other fan arrangements can be compared by duty, opening and maintenance needs.
Use the required house airflow and static-pressure curve to select a fan combination; do not use a free-air catalogue figure alone.
Review shutter movement, guards, weather exposure, dust control and access for cleaning and inspection.
Confirm motor supply, speed control, staged operation, alarms and the connection to the house climate-control panel.
Measure house length, width, height, openings, insulation, roof shape and internal obstructions.
Note bird density, equipment heat sources and the intended operating season.
Set the intended pad-inlet side, exhaust side, inlet control and air movement through the occupied zone.
Check for short-circuiting, dead zones and bypass air around the pad.
Review target airflow, air speed, static pressure, heat load and the local dry-bulb/wet-bulb range.
Use the selected fan curve and pad pressure loss to confirm the arrangement.
Confirm electrical supply, water source, drainage, pump location, controls and service clearances.
Provide a maintenance route for pads, basins, pumps, shutters and fan guards.
Test staged fan operation, pad wetting, air inlets, sensors and alarms before the high-load period.
Record actual temperature, humidity, airflow and water behavior under site conditions.
The following checklist is the practical input set for a poultry-house cooling review. It is not a fixed performance promise.
Cooling performance and component service intervals are reviewed against the actual house, climate and maintenance plan; no universal temperature, efficiency or energy result should be assumed.
Evaporative cooling depends on clean air paths, even water distribution and correctly staged fans.
Inspect for scale, dust, algae, damaged edges and uneven wetting. Clean or replace media according to the approved procedure.
Check pump, basin, filters, pipework, float or level controls, bleed-off and drainage before the cooling season.
Inspect blades, belts, bearings, shutters, guards, vibration and electrical connections with services isolated.
High humidity, poor house sealing, insufficient airflow or inadequate drainage can reduce the useful result and require a revised operating plan.
The system supports poultry-house climate control; it does not by itself guarantee animal performance, disease prevention, welfare outcomes or a specified indoor temperature.
The current OVOWELL page is being repositioned around poultry-house climate control. A final design should be matched to the house dimensions, bird load, climate and ventilation path.
Water evaporates from the pad surface as air moves through it. The available cooling margin depends on dry-bulb and wet-bulb conditions, pad selection, airflow and house leakage.
No. Fan duty must be checked against the selected pad, static pressure, inlets, house resistance, shutters and the required airflow stages.
Pad height, width, thickness and flute arrangement are selected from the approved model range and the wall opening. Send the house opening and target duty before choosing a panel size.
No. Temperature and humidity results depend on climate, house construction, heat load, airflow and operating settings. OVOWELL reviews the design conditions before quotation.
Provide the water source, quality, filtration, basin, bleed-off, cleaning and drain route. Scale, dust and algae can change pad performance and maintenance intervals.
Send house drawings, local climate data, bird density, target air speed and temperature, current fan and inlet layout, power, water, drainage and photos of the installation area.
Poultry-House Climate Review
Send the house dimensions, climate data, bird load, target airflow, static pressure, pad openings, fan layout, power, water and drainage conditions. OVOWELL can review the air path and system interfaces before quotation.
