Semi-Dry Fog air cooling for Swinery & Beef barn



Issues in meat farms, swinery and beef barn during warm weather

  • Heat stress / fatigue
  • Loss of appetite which generates a loss of weight in the animal
  • Animal losses
  • Lower productivity (lower quality and quantity of meat)
  • Lower conception rate due to hot environment




Solution: Semi-Dry Fog air cooling systems

Cooling down the barns without causing additional stress to the animals is important.  Our air cooling systems cool effectively without wetting the animals or the ground by using the evaporative cooling effect of very fine “Semi-Dry Fog®”. The animals are cooled down by reducing the surrounding air temperature with fog. It also keeps the barns very hygienic.

The installation of the system is adapted to each barn style.
