At this year’s EuroTier, Big Dutchman will present a new ventilation concept which can reduce exhaust air treatment costs in pig houses by up to 50%. “With our SmartAir concept we can create two separate air flows inside the house“ explains Big Dutchman product manager Andreas Kerßens the patent pending basic idea. “This way significantly less harmful gases are released in the animal area. Only a small share of house air beneath the slatted flooring still has to be sucked off and filtered.” In consequence, this means the exhaust air filter can be designed much smaller than before. It still achieves an impressive degree of efficiency of up to 70 % of ammonia precipitation.
