Home Climate Solutions Poultry Ventilation Combi-tunnel ventilation

Key considerations for combi-tunnel systems:

Poultry-temperature-608

Climate adaptability

Ideal for regions with seasonal or fluctuating temperatures, combi-tunnel ventilation automatically shifts between side and tunnel airflow. This ensures consistent climate control in poultry houses, no matter the weather.

Smarter ventilation for broiler and layer success

Poultry-combi-tunne-broiler-768

Optimized climate control for broiler production

Combi-tunnel ventilation is the industry standard in modern broiler production, combining side ventilation for air quality in colder seasons with tunnel ventilation to manage heat stress during warmer months.

  • Reduces Heat Stress, Improves Feed Conversion
    During hot periods, tunnel ventilation creates a wind-chill effect and can be paired with evaporative cooling to keep broilers comfortable. This supports high feed conversion ratios (FCR) and improves animal welfare.
  • Maintains Air Quality and Litter Health
    Effective minimum ventilation brings in fresh air to control CO₂, ammonia, and dust levels. Controlled airflow through air inlets reduces drafts and helps maintain dry litter — essential for leg health.
  • Boosts Efficiency with Low Energy Use
    Our variable-speed E-line fans reduce electricity and fuel consumption while also minimizing noise — improving both farm efficiency and working conditions.

Superior environmental control for layer production

Combi-tunnel systems are also ideal for layer houses, combining side ventilation for air quality during cold periods and tunnel airflow to reduce heat stress during hot weather.

  • Supports Stable Egg Production
    High temperatures can reduce laying performance. Tunnel ventilation with evaporative cooling lowers the risk of heat stress and helps maintain consistent egg production, even in hot climates.
  • Ensures Uniform Air Distribution
    Clean air must reach all hens — not just those near inlets or fans. Properly designed air inlets, equipped with accessories, ensure balanced airflow across the entire house.
  • Maintains Light Control During Rearing
    Light management is critical in rearing stages. Exhaust fans fitted with light filters help maintain precise light programs regardless of external lighting conditions.

FAQ

Find answers to the most common inquiries about combi-tunnel, system performance, and how to choose the right solution for your farm.

What’s the difference between side ventilation and tunnel ventilation?

Side ventilation brings fresh air in through side inlets, ideal for minimum ventilation and cold weather. Tunnel ventilation uses high-speed airflow from one end of the house to the other, providing strong cooling during hot weather.

Can combi-tunnel ventilation be installed in existing houses?

In most cases, yes. Many existing poultry houses can be upgraded to combi-tunnel systems with proper planning, structural assessments, and some retrofitting.

What are the requirements for a house to use combi-tunnel ventilation (e.g., airtightness, insulation)?

Key requirements include good airtightness, proper insulation, and well-sealed doors and inlets. These factors ensure efficient airflow and consistent climate control.

How to calculate the number of fans needed for combi-tunnel ventilation?

Fan sizing depends on bird type, stocking density, house dimensions, and target air exchange rates. The best approach is to speak with our poultry experts—they combine years of field experience, advanced ventilation design tools, and a deep understanding of each farm’s unique goals. There’s no one-size-fits-all solution in poultry, and a tailored design ensures optimal performance and energy efficiency.
