Further cooling solutions can be added to your ventilation system

Soaking:
Sprinkler systems wet the cows with a large droplet and then use fans to blow across the cow’s bodies to evaporate the water and cool the cows. In most cases a pipeline is installed next to the feeding area and mounted with low pressure 180° nozzles spreading the water over the cows’ back. A spray pattern with a radius of max 2.40m is wanted so the freestalls don’t get wet. Nozzle size determines rate. Only the correct pipe diameters, pressure regulators, thermostats and timers make the system complete and successful.

Misting:
High pressure fogging systems for evaporative cooling are used to cool the air above the cow without wetting the cow. A fog-ring is mounted on the fans consisting of 6, 8 or 10 nozzles. A high pressure water pump supplies the water to the nozzles at 70 Bar, to the nozzles, where a fine mist vaporizes, absorbing the heat and transferring it away from the cow. Depending on the humidity level in the barn, temperature drops of 3-5°C can be reached. Important is the control of humidity levels and the settings made on the controls.

Misting reduces the temperature by another 3-5 degrees C in addition to the 4-5 degrees C cooling achieved from ventilation alone. Misting is recommended in high density areas such as collection yards.
