Oxygen rich air to the birds from day one!


From first day of production the Corona air inlet from DACS creates a perfect air distribution with plenty of temperate, oxygen rich air flowing into the bird zone, thus ensuring a perfect climate for the birds to use their full growth potential.

Birds grow to their full potential

Depending on ventilation requirements, the Corona air inlet mixes the incoming air with the warm room air accumulated under the ceiling and distributes this preheated air accurately and evenly throughout the house. This constant and gentle flow of air allows the birds to grow to their full potential. On top of this the utilization of the warm room air under the ceiling reduces the heating cost by up to 70% compared to other ventilation systems.

Preheated oxygen rich air

The Corona air inlet is unique in the industry and is widely accepted as the best tool to ensure dry bedding, animal welfare and bird performance. The reason is the constant and gentle spread of preheated oxygen rich air to every corner of the house.

The brothers Jack and Mark Renders

The brothers Jack and Mark Renders in Son & Breugel in The Netherlands produce 185,000 regular broilers in five houses. They chose DACS ventilation and controls for their new house, commissioned in September 2019 and here is what they have experienced with their new DACS house compared to their other houses.

Easier to operate

“The constant flow of preheated air over the chicks from day one is a major advantage of the DACS ventilation system compared to our houses with negative pressure ventilation systems. The new system is just so much easier to operate so we always have a dry and well-ventilated house – no matter the season. One would think we would be adding more heat to get the improved climate in the new stable, but we actually save 70% on the heating cost compared to our other houses”, Mark says.

Blow of preheated air

“We know all too well that increased CO2 levels reduce the animal’s growth potential. But with the DACS system, thanks to the Corona inlet fans, the constant flow of temperate air in the bird zone lifts the CO2 off the floor and out of the house via the roof mounted exhausts. This contributes to a much better air quality in our new house and we can see that the birds are stronger. The birds really pay back on the much better climate in the DACS house” Jack explains.

Improved technical performance

“We clearly improved the technical performance in our new house. The slaughter quality is better and where the other houses have 1% rejection the new house it is 0.3 to 0.5%. The growth is slightly better and the feed conversion a few points lower in the DACS house. This does not seem like much, but everything adds up and we earn more money from the new house,” says Mark.
