The DLG’s so-called ‘Signum’ tests confirmed the energy reduction claim. They showed that the new air washer system was certified to have an air washing capacity of around twice as high (volume flow of 17,500 m3/h) and it also reaches very profitable energy usage values.
Andreas Kerssens, product manager, Big Dutchman, said, “The HelixX has now become a real alternative to external central air washers from a perspective of farm costs. This comes on top of already existing favourable investment costs.”

Dust and ammonia
This type of air washer system works without filling and filter material which leads to reduced maintenance costs. HelixX can be added to a pig house without external construction and subsequent external construction works and costs. On top of that, the decentral air washer has shown good results when it comes down to filtering dust and ammonia from the air. Figures by DLG show: “The dust emission reduction is 85%, and ammonia reduction is 87.5%.”
Kerssens said, “Apart from energy reduction we have also managed to reduce ammonia emissions.”
Simple construction
In essence, HelixX consists of many nozzles on top of a spiral fan. The nozzles will moisturise the emerging air, thus absorbing both dust and ammonia. The decentrally located air washer units are connected to each other as well as with the central water cleaning station.
Every air washer unit works individually. This way, he operating costs, especially power costs for recirculation of the wash water, can be reduced to a minimum. The company’s product development team also considered security issues, as in case of a power cut, natural thermical processes inside the chimney will continue to guarantee that a part of the air will still be transported outside.
In addition, security fire valves, compulsory in at least some regions in Germany, can be adjusted inside the air channel.
The German company writes in a press release: “For many pig producers in regions having a high livestock density, the supplementary air washer, is one of the few options to consider in order to continue business on the same location within the boundaries of the law.”
