Poultry House Environmental Control System  

Product Overview

The poultry house environmental control system is an integrated package of ventilation, cooling, and intelligent control equipment engineered for modern poultry buildings – designed to maintain optimal indoor climate (temperature, humidity, air quality) year-round for layer, broiler, breeder, and pullet flocks, regardless of external weather conditions.  

The complete system includes:  

• High-efficiency exhaust fans (installed on end/side walls) for air exchange;  
• Evaporative cooling pads with closed-loop water circulation systems for temperature reduction;  
• Insulated air inlet windows + air deflectors for uniform fresh air distribution;  
• Intelligent environmental controller + electrical control cabinet (system "brain").

By coordinating these components, the system ensures precise air exchange (0.5–4 m³/bird/hour), temperature regulation (20–28°C for layers), and humidity control (50–60%), reducing heat stress by 80% and cutting energy consumption by 15–20% vs. manual control – directly boosting bird health and production performance.  

System Components

1. Ventilation Fans

High-efficiency axial flow fans create negative pressure inside the poultry house, exhausting hot/humid air while drawing in fresh air via inlets/cooling pads. Key features:  

• Diameter: 36–54 inches (customizable), air volume 20,000–45,000 m³/h per fan (at rated static pressure);  
• Construction: Galvanized steel/stainless steel housing + blades (corrosion-resistant, service life 8–10 years);  
• Safety design: Automatic shutters (prevent reverse airflow) + protective grilles (bird/worker safety).

2. Cooling Pads

Evaporative cooling pads (installed opposite fans) reduce inlet air temperature by 8–12°C via water evaporation. Key features:  

• Material: Specially treated cellulose (high water absorption, anti-mold, service life 3–5 years);  
• Thickness: 100–150 mm (optimal for evaporation efficiency);  
• Frame: Galvanized steel/aluminum profiles (rust-proof, easy assembly);  
• Water system: Closed-loop circulation with filter + float valve (water saving 30% vs. open systems).

3. Air Inlet Windows and Deflectors

Insulated side wall inlets + ceiling air deflectors ensure uniform fresh air distribution:  

• Side inlets: Insulated doors (airtight when closed) with adjustable opening angle (0–90°);  
• Deflectors: Guide fresh air upward/along the ceiling (minimum ventilation mode), preventing cold drafts on birds and ensuring air mixing (temperature variation <2°C across the house).

4. Environmental Controller

The "brain" of the system, with real-time sensor feedback (temperature/humidity/pressure) and automatic equipment control:  

• Power: 220V/380V, 50/60Hz (customizable for local grids);  
• Functions: Multi-stage ventilation curves, timer control, cooling pump activation, alarm outputs (overtemp/underhumid), data display/storage;  
• Compatibility: Integrates with heating equipment (for cold climates) and farm management software (remote monitoring optional).

Typical Technical Specifications

The following table shows typical ranges for core components. Exact data (model numbers, air volume, pad dimensions) can be customized to match house size (100–10,000 m²), climate, and bird type (layer/broiler/breeder).

You can replace the ranges above with exact model numbers (fixed fan models, pad sizes, controller channels) for standard product lines.  

Working Modes

1. Minimum Ventilation Mode (Cool/Mild Weather: <22°C)

• Only 10–20% of fans operate intermittently (2–5 min on/10–15 min off);  
• Fresh air enters via side wall inlets (10–20% opening), directed upward by deflectors to mix with warm ceiling air – avoids cold drafts on birds, maintains CO₂ <3000ppm and ammonia <15ppm.

2. Transition Ventilation Mode (Moderate Weather: 22–28°C)

• Controller activates additional fans (30–70% of total) and gradually opens air inlets (30–80% opening);  
• Maintains negative pressure (10–20Pa) and air speed (0.5–1.0 m/s) to remove excess heat without cooling pads.

3. Tunnel Ventilation & Cooling Mode (Hot Weather: >28°C)

• 100% of tunnel fans run continuously, drawing air through wet cooling pads;  
• Inlet air temperature reduced by 8–12°C, air speed increased to 1.5–2.5 m/s (tunnel effect) – rapidly removes heat from birds, reducing heat stress mortality by 90%.

Advantages for Poultry Farms

1. Stable, stress-free climateAutomatic control maintains temperature (±1°C accuracy), humidity (±5% RH accuracy), and air quality within optimal ranges – eliminates heat stress (summer) and cold drafts (winter), reducing mortality by 30–40%.
2. Enhanced production performanceComfortable environment boosts feed conversion ratio (FCR) by 5–8% (broilers) and egg production by 4–6% (layers); broiler weight gain increases by 7–10%, and layer peak production lasts 2–3 months longer.
3. 15–20% energy + 70% labor savingsMulti-stage control avoids unnecessary fan/pump operation (cuts electricity costs by $0.01–$0.02 per bird/year); farmers only set parameters (no manual equipment switching – 1 worker manages 100,000+ birds).
4. Improved biosecurity & healthNegative pressure + uniform air flow reduces dust (60%), ammonia (40–50%), and harmful gases – lowers respiratory diseases (e.g., mycoplasmosis) by 35% and antibiotic use by 20%.
5. Climate/scale flexibilityCustomizable for hot (tropical), cold (temperate), or humid climates; fits small family farms (5,000 birds) to large commercial complexes (500,000+ birds), and H/A-type cage systems or floor rearing.

Packaging, Installation & Service

Packaging

The system is supplied as a complete set, with each component packed separately:  

• Fans: Protected by waterproof film + wooden crates (blades/housings secured to avoid damage);  
• Cooling pads: Rolled cellulose pads + galvanized frames (labeled by section);  
• Air inlets/deflectors: Boxed with hardware kits;  
• Controller/sensors: Anti-static packaging (electrical components) + installation manuals (multilingual).

Installation & Commissioning

• Custom layout design: We optimize fan/pad/inlet positions based on house dimensions (length/width/height) to ensure uniform air flow (velocity variation <10% across the house);  
• Professional calibration: After wiring/plumbing, our engineers program the controller with climate-specific set points (e.g., 24°C for layers, 26°C for broilers) and age-based ventilation curves (pullet → adult);  
• On-site training: Optional hands-on training for your team (controller operation, sensor calibration, routine maintenance).

After-Sales Service

• Warranty: 1-year warranty for controllers/sensors; 2-year warranty for fans; 6-month warranty for cooling pads;  
• Remote support: 24/7 technical support (video call/phone) for controller troubleshooting or parameter adjustment;  
• Spare parts: Stocked fans, pads, sensors, and controller components (7–15 day delivery to Africa/Middle East/Southeast Asia/Latin America);  
• Lifecycle support: Free annual system health checks (via remote monitoring) to optimize efficiency.

With precision design, professional installation, and intelligent control, this environmental control system is the foundation of efficient, sustainable poultry production – delivering a return on investment (ROI) of 6–12 months for commercial farms.  

If you need region-specific adjustments (e.g., high-temperature upgrades for desert climates, low-temperature heating integration for cold regions, or language localization for the controller interface), we can refine the specifications to match your target market’s needs.
