Dairy barn fans

A pleasant barn climate contributes to healthy and productive dairy cattle. Especially when outside temperatures are high, ventilation is of vital importance. By using the right fans heat stress can be prevented.

Maintain milk production using circulation fans

An optimal living environment for dairy cattle requires a good climate. After all, a pleasant barn climate contributes to healthy and productive cows. In order to prevent heat stress, ventilation is particularly important at high temperatures. From 22 ºC upwards, cows eat less and milk production decreases. Other side effects of heat stress include fertility problems, reduced resistance and a higher risk of mastitis.

These problems can be prevented by blowing refreshing air around the cows. This reduces the apparent temperature and safeguards your cattle's milk production. A minimum air velocity of 2 m/s is essential to achieve this effect.

Fans for dairy cattle

Modern, highly productive dairy cows must live under optimum climate conditions all year round. To reduce heat stress in dairy barns, we offer a diverse range of Multifan and EMI fans.

Our Dairy Fan (basket fan) has been specifically developed for dairy barns. With its high throw and high air output, this fan maintains a minimum airspeed of 2 m/s over a long distance. For barns with a lower ceiling, we recommend smaller basket fans. The Dairy Fan and the smaller basket fans can, of course, also be combined.

Our Ceiling Fan is ideal for milking parlors. This fan creates a pleasant vertical air displacement around the cows. As a result, the cow experiences less heat stress and has fewer issues with flies.

Tube ventilation
In addition to the aforementioned solutions, tube ventilation is another option you could choose. With this type of ventilation, a wall fan sucks fresh air from the outside and transfers it inside the barn through a tube. The tube has holes in it and therefore ensures that the fresh air is delivered to the dairy cows throughout the barn at low speed.

Basket fans prevent heat stress in cows

Farmer Dries Lahousse from Elverdinge is active in arable farming and breeds poultry, but also owns a dairy barn housing 170 cows. Amongst those are also several older animals that have already produced more than 100,000 liters of milk. In order to maintain production throughout the year for all cows, including the oldest ones, he recently invested in basket fans, for extra cooling on top of the natural ventilation. 

Dries’s barn consists of two parts, one measuring 50 by 18 meters and the other measuring 40 by 26 meters. “It is not a big barn, considering it’s housing so many animals, and the orientation isn’t optimal, which can rapidly lead to high temperatures in the summer months”, says Wout Goderis of Goderis CowCompany. “However, it is too large to use a tube ventilation system efficiently. That’s why we have opted for seven big basket fans above the stalls, that start automatically when the barn temperature rises too much.”

The fans are a perfect match

“These fans each have a 131-centimeter diameter. I have set the motors to a starting temperature of 18°C, at that temperature they work at 20%. And at a temperature of 24°C the fans run full speed. This way, the air speed just above the backs is never higher than 2 meters per second and there is no palpable draft”, Dries explains. “The result is fewer flies, drier stalls and, above all, better animal welfare. It reduces my veterinary costs and it leads to higher fertility rates and higher productions. And yes, even the older cows remain at the same production level all year round!”

As a result, the dairy farmer thinks he will have already earned his fans back in just three to four years. “I was able to receive 30% VLIF support for this investment, because it’s a sustainability investment. And the electricity costs are also not too bad, because the motors are frequency-controlled and because I have solar panels on my poultry houses. The panels produce most of their power in the summer months and they are, therefore, a perfect match for the fans”, he adds.
