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.
Ventilation
“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
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.
Controllers
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.
