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.
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.

The fogging system works with a high pressure pump at 70 Bar, and by means of special nozzles the water is nebulized into drops of just 10 microns. The nebulous water evaporates instantly, lowering the ambient temperature. The soaking system works with a low pressure system of 1,3 Bar. The soaking nozzles are placed above the feeding table with a pipe or the nozzles are placed above the holding area.
