Improve air distribution in wide houses with chill units
A case story from Poland
Bromargo is one of Poland’s leading poultry businesses with hatcheries, rearing farms, breeding farms, and a specialized fleet for the transportation of hatching eggs and chicks.
To accommodate the request for two nest areas in each breeder house, Bromargo chose to build extra wide houses up to 24 meters. A wide house with more breeders is an efficient way of increasing production. However, the width of the house and the two rows of nest areas soon turned out to be a challenge for the air distribution inside the house.
A challenge in wide houses
Usually, in an ideal scenario, air enters through wall inlets, follows the ceiling, reaches the middle of the house, and drops to the ground, where it reaches the birds and continues toward the walls. Because of the house width, the air could not reach the center of the house before it dropped to the ground. Another big challenge was the two rows of nesting areas running from one end of the house to the other. The nests became big obstacles for the air causing minimum air movement between the nests and the walls. Lack of air movement between the nests and walls caused wet litter, which led to increased ammonia concentrations and an increased risk of footpad dermatitis. The uneven climate caused the birds to huddle together in groups, resulting in many floor eggs rather than laying them in the nests.
Recirculate the air to go further
The solution proved simple but very efficient – DA 65-600 chill units to recirculate the air. We suspended the chill units from the ceiling, where they recirculate the air and distribute it throughout the house. The chill unit can throw the air far, making it possible also to reach the areas between the walls and the nests, causing a nice uniform climate in the house.
Since installing the chill units, Bromargo experienced a significant improvement in the house climate. The chill units have caused so much air movement in the house that they no longer struggle with wet litter. The improved climate caused a more comfortable environment for the birds in the nests, resulting in fewer floor eggs. The farm manager also noticed less huddling by the birds and a more even distribution of birds on the floor.
