Ventilation is the "breathing system" of a poultry house. 

By regulating airflow, removing harmful gases (ammonia, CO₂), and stabilizing temperature and humidity, it directly influences bird health, productivity, and operational efficiency. 

Our solutions combine innovation and precision, giving you consistent results and a measurable return on investment.

1. Core Components Of Modern Ventilation Systems

Fans

Air Inlet Window

(1) Fans And Negative-Pressure Ventilation

Negative-pressure ventilation uses exhaust fans to draw air out, creating slight negative pressure that pulls fresh air through inlets.

This approach ensures predictable airflow and allows precise control of the house environment—the foundation for high-performing farms.

• Design considerations

Minimum ventilation rates per bird or weight for idle/cold conditions.

Maximum airflow required for summer/tunnel ventilation based on house geometry and target airspeed.

(2) Ventilation Modes And Seasonal Adjustment

• Tunnel / Longitudinal Ventilation

Fans at one end, wet pads or uniform inlets at the other. Produces horizontal airflow, creating wind-chill. Target airspeed: 2–3 m/s for broilers; lower for layers.

• Cross / Lateral Ventilation

Fans and inlets on opposite walls. Lower airspeed (0.1–0.3 m/s) minimizes draft stress in moderate climates. Ensures layers stay productive year-round.

• Vertical / Displacement Ventilation

Fresh air enters near the floor or cage bottoms and rises naturally to roof exhausts, enhancing stratification and reducing cross-contamination.

(3) Wet Pads: Evaporative Cooling

Wet Pad

Wet pads reduce incoming air temperature by evaporating water, adding humidity while lowering dry-bulb temperature.

 Performance depends on outdoor humidity, airspeed through the pad, and consistent wetting.

(4) Sensors, Controls & Smart Management

Modern systems use distributed sensors and automated controls to maintain perfect climate conditions:

• Sensors

Temperature & humidity at bird level, static pressure, ammonia/gas levels, fan speed, and wet-pad flow.

• Controls

PID Control for smooth adjustments, reducing stress on birds.

State-Machine logic for staged fan/pad operation.

Body-sense correction adjusts setpoints to reflect bird-perceived temperature.

2. Layer House Applications

Poultry Cage System

(1) Goal: Maintain consistent conditions for high egg production and feed efficiency.

(2) Ventilation: Negative-pressure with cross or tunnel airflow.

(3) Airspeed: 1.5–2 m/s for summer cooling; minimum night ventilation removes ammonia and CO₂.

(4) Wet pads: Moderate use during hot periods; coordinated with fan staging to avoid humidity spikes.

(5) Smart controls: Maintain 18–24 °C, supporting stable laying cycles.

3. Broiler House Applications

Broiler Deep Litter System

(1) Goal: Rapid heat removal to accelerate growth and maintain litter quality.

(2) Ventilation: Tunnel airflow at higher speeds; ensures wind-chill cooling.

(3) Target Airspeed: 2–3 m/s in the bird zone.

(4) Wet Pads: Aggressive use during heat; pad size coordinated with fan capacity.

(5) Smart Controls: Staged PID fan control with pre-cooling sequences prevents sudden humidity changes.

4. Pullet House Applications

Chick Deep Litter System

(1) Goal: Gentle, precise climate to ensure healthy early growth.

(2) Ventilation: Minimum airflow in early stages; control gases without drafts.

(3) Airspeed: < 0.3 m/s, increasing as birds grow.

(4) Wet Pads: Introduced only as birds age and ambient temperatures rise.

(5) Sensors & Controls: Staged airflow changes with age; sensors at chick-back height for accuracy.

5. Integrated Environmental Management

Across layers, broilers, and pullets, modern systems integrate fans, wet pads, negative-pressure ventilation, and smart sensors to:

(1) Reduce disease risk and ammonia exposure

(2) Maintain uniform temperature and airflow

(3) Optimize feed conversion and growth

(4) Lower energy consumption through automated, data-driven control

6. Real Farm Application: Integrated Smart Ventilation Across Poultry Houses

This real-world example shows that intelligent, integrated ventilation systems can deliver measurable improvements across multiple poultry house types. 

With one interface managing three house types, farm managers joked that "monitoring birds has never been this relaxing"—proving technology can be both efficient and stress-free.
