Aerotech Ventilation Products - Dairy ventilation systems

Cooling in your dairy shed

An investment that earns its worth

• Additional air circulation promotes heat output
• Reduced risk of heat stress
• Keeps milk yield high

Heat stress

Each year, heat stress causes a decline in milk yield. A copious supply of clean drinking water is therefore a primary requirement, while an accurately regulated ventilation system and perhaps water cooling provide the ideal complement.

Mechanical ventilation

Although natural ventilation is usually a sound means of cooling cattle sheds, it is simply insufficient when the outdoor temperature rises above 25°C. Mechanical can provide the solution. The use of special high capacity Aerotech fans can reduce the ambient temperature by anything from 2 to 6 degrees, thus resulting in improved heat emission. This is usually adequate to retain a high milk yield.

Automatic control saves energy
The fans can be controlled automatically using a DCC-1 temperature regulator and speed control. And by opting for an Aerotech frequency regulator for rev control, you can also substantially cut your energy costs!
Ask your local dealer about the best solution for your business.

Additional cooling combined with fans
Cooling can be improved even more by installing a water pipe along the feeding rack, fitted with nozzles with larger water droplets. However, this does also depend on fans being installed.

Positioning the fans for the best effect
Trials have shown that the best possible effects can be achieved by installing fans both above the walkway in front of the feeding rack and above the freestalls themselves. The fans can best be positioned at a height of 2.40 to 2.50 m and a downward angle of around 15 to 30°. The spacing between the fans depends on the capacity and throw of the model chosen.

Water cooling
Additional cooling can also be achieved by fitting a combination of fans and a sprinkler system. Fans can also be installed in the gables, to draw air in at one end of the shed and expel it at the other end. This type of system can provide even greater cooling capacity if used in combination with a cooling system with cooling pads.

Heat emission is improved, while maintaining optimum feed consumption and milk yield. Ensure that the climate in your dairy shed is more comfortable than in the pasture!
