BENEFITS
- Easier control (cold air more easily directed upwards)
- Air flow velocity controlled across the poultry right up to the plumage
- Homogeneous temperatures, bedding and aeration for poultry
- Gradual and tailored transition (gradual engagement of gable positioned turbines in addition to chimney shafts)
- Gradual increase in longitudinal air speed (depending on the number of extractors used on the gable)
- Tunnel effect for cooling poultry at the end of a batch or when outside temperatures are high
- Can be combined with Cooling or HP misting (if the climate is not humid)
