Growing towards a fully closed calf farm
In Barneveld, the van Laar family runs a farm with 740 calves. Construction of the new barn began in 2021 and the first calves have recently entered the barn. With the construction of the new stable, a cherished wish has become reality. It creates a closed farm. There is now the possibility to fatten all the young cattle on one location. This gives the family more grip on their part of the chain and thus takes a step towards making the process more sustainable. The new barn is equipped with a chemical air scrubber supplied through our dealer Boon Agrosystems.
Air scrubbing – a centre point
In the middle of the barn, the animals are cared for as well as fresh air supply to the departments from a central corridor. On either side are 370 animals in pens. The department is controlled on temperature and airflow by means of a Steinen climate computer. The entire barn is ‘under pressure’ and the airflow is regulated by means of various inlets. The entire climate management is also provided by Boon agro systems.
In order to maintain a good air distribution, it was decided to equip each half of the house with an air scrubber. This creates an even air flow to the ventilation wall. The two air scrubbers are placed against each other with their rear sides. This creates a good ventilation pattern on both sides, making the scrubber the centre point of the climate system.
Certified air scrubbers for optimal results
Both scrubbers are supplied with water from the technical room and each complies with BWL 2007.05.V7 that reduces 95% ammonia, 30% odour and at least 35% fine dust. In consultation with the client and the dealer, it was decided to apply an increased flow rate to the scrubbers. This was chosen because the air supplied is very sticky and this ‘dilution’ helps to reduce the frequency of cleaning. The result is a high-quality unit with excellent removal efficiency and low maintenance requirements.
Good preparation for easy installation and commissioning
Before the scrubbers were installed, there was frequent contact between the client, contractor Boon Agrosystems and Inno+. Because they chose to place the scrubber in the roof, extra emphasis was placed on how to integrate it. In the factory, the set-up was built and tested according to our FAT (factory acceptance test procedures). By doing this, we can guarantee a well-functioning washer once it’s running on site.
Mid May, the modules were transported and placed on the prepared platform in the barn. Boon employees took care of the installation of the piping as well as the acid room with the corresponding safety measures. After all this was completed, the Inno+ trained (ICEplus+) mechanic of Boon agro systems started up the washers. The knowledge and skills these mechanics have also guarantees an optimal functioning of the washers.
Blue print for the future
With the increased focus on our sector about emissions and carbon footprint. It is essential building design in the future, integrates the technologies available to achieve the levels of reduction required. This will allow us to keep farming. This project is a showcase example of how we can achieve this.
