The ideal cooling system for poultry houses with tunnel ventilation

An innovative pad cooling system developed by Big Dutchman, the RainMaker uses evaporation to cool barns and is therefore mainly installed in regions with hot and dry summers. The higher the temperature and the lower the relative humidity, the higher the cooling effect.         

The rainmaker’s main benefits include efficient cooling of the barn, minimum installation requirements, and easy monitoring and maintenance.
