At the end of the central drain, two air scrubbers are installed, each with a capacity of 78,000 m3 air per hour. These biological scrubbers are constructed in accordance with BWL 2010.02.V6 and have a minimum ammonia reduction of 85%. During the washing process, the heat from the stall air is captured in the process water. This process water is the source of heat for the pre-conditioning of the stables.
The heated process water and the process water from the existing stable are fed into a central process water tank. This is where the parameters and operation of both scrubbers are centrally controlled and logged. But this is also the place where the heat is extracted by means of our Triple EEE system. By means of a separate system, the heat is transferred to the secondary circuit and pumped towards the inlet exchangers.
At the front of the house, there are four inlet exchangers, each with a capacity of 120 kW. With this installed capacity, it is even possible to pre-condition at -10° Celsius outside air temperatures. The heat enters the department through the perforated ceiling.
