Heat stress occurs when the cow cannot dissipate its body heat sufficiently. Heat stress can occur from 21 degrees Celsius and causes many problems in cows. From more claw problems and mastitis to reduced milk yield and fertility problems. That is why a good stable climate with fresh, moving air is a primary need for your cow.
During windless or warm days, even the best is natural ventilation not enough to maintain the temperature in the stable. By adding good cooling fans, this is possible.
Cooling cows can quickly be done! Dairy farmers who ventilate the stable experience significantly less loss of milk production in extreme heat. Moreover, production is back on track more quickly.
With ventilation with axial fans, a horizontal air flow is created over the length or width of the stable. DSD supplies various types of axial fans.
The ABBI-FAN 140 XXP-21 fan is the latest development from Abbi-Aerotech for dairy stables. This fan is the most economical in the market as far as axial fans are concerned.
The ABBI-FAN 140-XXP fan is equipped with a permanent magnet motor and an associated electronic control. This means that a very high efficiency is achieved, which becomes even greater as the speed decreases. Being in practice energy savings of 30-70% measured compared to existing engines. The engines are significant stiller, have a longer life span en less maintenance required.
The ABBI-FAN XXP is optionally available with atomization, which spreads very fine water droplets. This allows the air temperature to be further cooled by approximately 3-5 °C.
The DCC touch automatic control makes it possible to optimally adjust the fans. With the help of sensors, the stable climate is kept as optimal as possible fully automatically.
At the De Gelder cheese farm in Tijnje, the Abbifan XXP fans hang in the dairy barn. Farmer Hans Peter talks about his experience with installation and use of the fans.
Axial cooling fans are generally placed in line, behind feeding barriers and above the walkway. Several fans keep the feeding areas cool.
Correct hanging heights and mutual distances are important guidelines for optimal circulation.
Axial cooling fans can be used individually and in series, from simple to automatic systems. The automatic systems are controlled per closed circuit by a thermal protection switch, thermostat and a 5-position transformer.
The fans are equipped with 380V motors.
It is important for all stables, old or modern, to provide sufficient fresh air.
In modern stables with open sides and a gutter height of 4.40 meters, fans can be placed in the side wall, so that fresh outside air is blown directly over the animals. We call this cross ventilation. If possible, it is recommended to hang the fans on the shady side. The distance between them will then be approximately 7 meters.
In outdated stables, the gutter height is often too low for cross ventilation. In that case, longitudinal ventilation is therefore chosen, whereby the fans are placed in the stable in the longitudinal direction to blow fresh air through the stable.
