Ventilation and cooling systems

Even if the temperatures today do not make us think about the summer, we know very well that the change of season and the increase in temperatures could come suddenly.

And we know very well that animals in a stable that is not well ventilated and refreshed, will suffer very high temperatures, with an inevitable decline in production and this will result in a loss of profit for the breeder.

The optimal temperature for the cattle goes from 7 °C to 20 °C, and the humidity rate around 40/50%.

Over these values ​​the body temperature will start to rise and the animal will ingest less food; consequently the reproductive parameters will worsen, and the milk produced will start to decrease in terms of both quantity and quality (fat and protein).

To avoid or reduce these losses, a few small measures are sufficient.

Our ventilation and cooling systems, studied in every detail, are excellent systems to combat heat and to limit the problems deriving from it.


“Due A” destratifiers have a “Brushless” motor with permanent magnets with integrated electronics, a power of 0.5 to 1 kW, very high energy efficiency, low power consumption and maximum silence.

To this motor is fixed an anti-fall impeller, which supports 6 aluminum blades, complete with deflectors.

The diameter varies from 2 to 7m, depending on the size of the barn.


Cooling systems, on the other hand, include a fan system to ventilate the dormitories, and a second system on the supply area.

It consists of two elements: the showers that bathe the animals, and the fans that, inserted in the feeding lane, dry the cows’ mantle, extracting the heat and lowering the body temperature.


The latest generation control unit works combined with temperature and humidity probes that allow continuous control of environmental conditions, and regulates the speed of the destratifiers, increasing or decreasing it automatically. In the event that the ventilation system is coordinated with the cooling system, the temperature / humidity probes transmits the data to the control unit, which regulates the bath-drying cycles, according to the environmental conditions.

Due A Srl offers advice for the sizing of the plants and the right design, based on the size and settings of the barn. A well-designed plant allows the farmer to quickly re-enter the initial investment, improving reproductive parameters and the quantity and quality of the milk.
