Cattle aerator for existing and newly built dairy stables

Discover the realisation

On two dairy farms, one newly built (400 dairy cows) and one existing (300) in Neeroeteren (Limburg), a Cattle aerator was installed to purify the outgoing stable air of the dairy cows from ammonia, odour and dust.  The Cattle aerator was developed in West-Flanders by CBgroep and is a total concept consisting of, among other things: air scrubbing unit, extraction fans, comfort ventilation control, control of curtains and cooling.

The CBgroep team guides the dairy farmer from A to Z: during the application for a permit, the elaboration of the drawings and the ventilation management, as well as with the actual assembly and start-up.

The installation was built on the basis of the PAS measure R-1.7 45% or higher ammonia emission reduction.  The legal online monitoring system records up to 64 items every 15 minutes, including in particular:

• 14x vacuum gauges
• 9x temperature sensors
• 3x humidity meters
• 8x CO2 meters
• 2x % ventilation
• 2x % position of inlet curtains
• pH acidity and mS conductivity of washing water
• fresh water and produced drain water quantities
• operating hours
• safety sensors such as level of drain water tank and circulation tank

The various values are clearly displayed in a graph.  In this way, the installation can be accessed from every computer or smartphone with internet access.  This user-friendliness makes it possible to provide technical support to the dairy farmer from the offices of CBgroep in Staden.  After the 2-year guarantee period, this way the costs for on-site interventions are reduced to a minimum.  This allows the dairy farmer to continue to concentrate on his main activities.
