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 when describing 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 extracted 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 removal.
“This is also due to the intelligent air guidance above the slatted floor which changes the air flow in the building in such a way that the air carries less ammonia from the manure section“, explains Kerssens. The new ventilation concept is an interesting alternative especially for new buildings and refurbished buildings.
Measurements of the concept under farm conditions have shown that the treatment of the volume flow of air removed by continuous underfloor extraction achieves a degree of efficiency of up to 70 % of ammonia removal. Thus significantly less harmful gases are released into the animal area, which also helps to improve animal health conditions.
