In both fattening pig farms and sow farms, it is necessary that the temperature in the departments does not become too high during the summer period. This applies in particular to heavier fattening pigs, sows in group housing, lactating sows and sows in the mating shed. Research has shown that the optimal house temperature for (medium) heavy fattening pigs is lower than 19 degrees Celsius, the temperature should in any case not exceed 24 degrees. If the temperature in the department rises in the summer to, for example, 30 degrees Celsius, an average fattening pig consumes 0.4 kg less food per day, which reduces growth by approx. 150 grams per day.

The optimal temperature for a lactating sow is below 21 degrees Celsius. A higher temperature can have negative consequences for the next litter. Cooling the mating shed is also very important. Without proper cooling, pregnancy rates drop visibly after the summer. According to EU guidelines, the prevention of heat stress is therefore mandatory when building a new farm.

There are various techniques for cooling down a farm. One of the techniques is the evaporation of water in the incoming air. The evaporation of water in the incoming air increases the relative humidity of the air. If the climate outside the stable is humid, warm weather, the cooling effect is reduced.

Genugten Agri Projects B.V. supplies completely plastic Coolpads, which have a very long lifespan and are easy to clean. The cool pads are available in various widths and heights. The capacity varies from 16,200 to 259,200 m3 / hour with a low air resistance of 10 Pa. The water is pumped from a float tank above the cool pads via an integrated energy-efficient pump. Because the air is sucked through the cool pads, the water evaporates and the air is cooled.

Relative air humidity

The cooling effect of this system is based on the evaporation of water. Because the water evaporates, the air humidity in the stable increases. The cooling effect of the Pad-cooling system is less effective when the air is humid. The table below shows the change of temperature (ΔT) in relation to the humidity percentage.
