Optimum climate is essential in order to achieve good production results as a poultry farmer. Effective temperature and humidity control requires that air from outside is brought to the poultry house in precise quantities. The CoronaD air inlet from DACS meets the challenges of modern poultry production facilities. The inlet mixes the incoming air and the warm room air in a way that gives a very comforting, well tempered air and ensures a nice, dry litter throughout the poultry house.

Gone is cold air fallout, draught, wet litter and the following ammonia vapor.

Optimizing the in-house climate
During the growth period - and depending on the weather outside - the mixing percentage of incoming air/warm room air is automatically changed to maintain the optimum temperature on the air entering the poultry house. The constant mixing and circulation of air keep on sending fresh oxygen-rich air down to the birds, keeps the litter dry and at the same time removes gaseous waste products. The production of ammonia from the litter is minimized when it is kept dry, and the movement of air removes CO2.

50 % saved on your heat bill

As the CoronaD effectively mixes and circulates the hot air in the poultry house with precisely measured amounts of fresh air from outside, it is possible to reduce heat supply by as much as 50 % compared to traditional ventilation systems - and at the same time ensure absolute optimum climate in the poultry house.

The unit utilizes the warm air already in the roof space simply by sucking it in down, mix it with air from outside and distribute this temperate air in the room and among the animals. A simple solution ensuring optimum climate conditions in the house and bringing big savings on heating - year in, year out.

When the need for cooling arises, the CoronaD forces cool air downwards through the center venturi. The cooling effect of this vertical air distribution provides the most efficient air cooling available in the poultry industry.

In order to achieve good results as a poultry producer it is essential that the climate in the poultry house is optimal. Effective regulation of temperature and humidity requires that air from outside is brought to the house in precise quantities.

During the growth period and depending on the time of year, the CoronaD very precisely mixes the fresh air from the outside with the warm air in the house. This makes sure that only heated air is distributed among the animals. This eliminates cold air fall out, draught and wet litter - and reduces your expenses for heating by as much as 50 %.

Climate optimization and energy savings
During the growth period - and depending on the climate outside - the mixing of air is automatically changed always adding the exact amount of air that is needed to maintain the optimum climate in the house. The mixture of fresh air from the outside and warm air from the house ensures a good climate and thereby optimum welfare for the animals. The constant circulation of heated air among the animals keeps the litter dry and removes CO2 and other gaseous waste products.

Marked Reduction of Heating Costs
The very precise mixture of warm air from the house and fresh air from outside in the CoronaD unit makes it possible to reduce heating costs by as much as 50 % when compared to traditional ventilation systems. The CoronaD utilize the warm air already in the roof space simply by sucking it in down, mix it with air from outside and distribute this temperate air in the room and among the animals. A simple solution ensuring optimum climate conditions in the house and bringing big savings on heating - year in, year out.

At low ventilation rates (when it is very cold outside and/or when the birds are small), the CoronaD preheats the air by mixing a minor quantity of cold incoming air with warm room air, before distributing the air evenly throughout the house, thereby eliminating draught and cold air fall out. Depending on the damper position in the chimney, the mixing percentage of incoming air/warm room air automatically changes. The breeze of tempered air effectively removes pollutants and keeps the litter dry. The result is an optimum climate keeping the animals healthy and in good growth.

When the weather gets warmer, the CoronaD works with partially opened dampers and mixes a larger quantity of incoming, cool air with warm room air. Still depending on damper position, the mixing percentage of incoming air/warm room air automatically changes. The desired temperature in the bird zone adjusts quickly and efficiently, ensuring even and appropriate temperatures, high air quality and comfort. As the need for higher air exchange rate in the house increases, the air flow pattern gradually changes from horizontal to a slightly downwards flow. As the temperature is still a mixture of warm air from the house and air from outside, further savings on the heating bill is possible, and the air among the animals will always be temperate.

When the weather is hottest, the dampers are in vertical position for maximum airflow. The mixing action is suppressed by the main flow. At this stage, the centre venturi acts as an extra discharge that allows for vertical air distribution. The CoronaD forces the cool air outwards and downwards, giving maximum airflow and air speed in the occupied zone. This unique air distribution pattern ensures abundant air supply and a high degree of thermal comfort. Fully opened dampers are used during hot weather with full grown birds.

Higher cooling effect
Studies have shown that the vertical air distribution pattern leads to significantly higher cooling effect than tunnel ventilation systems with equivalent air capacity, thereby reducing the heat load under hot weather conditions. The adjustment of the damper in the chimney is computer controlled, and no manual adjustment is needed.
