Case study Air mixer EliturboAGRI


The farm of this case study is specialized in pig farming and is located in the countryside of the province of Milan. The farm building dates to 1966, developed with an offset pitched roof with horizontal exhaust opening. In 2001, a renovation was carried out, the roof cover substituted and is now made of insulated sheet metal which allowed the straw to be completely removed from inside the farm. The floors are on grates, the feeders and the dividers are made of stainless steel, the window openings are run by an electronic controller that manages their opening by signals given by sensors placed throughout the farm. In 2008 the feeding system of the animals was updated with a completely computerized system. In 2018, in fulfilment of the ATS requirements, the grids were replaced with ones complying with the European regulations, within this improvement requirement was even introduced the study to improve the air distribution system by installing the air mixing system Eliturbo Agri, international patent of Impresind.


The main problem was the lack of air circulation inside the farm, especially during the summer season, as well as the lack of air changes necessary to lower the high concentration of ammonia vapours produced by the animals.


To solve this problem, an "Eliturbo" air mixing system was installed. The system consists of n°8 Eliturbo of 10.000 m3/h airflow each for a total of 80.000 m3/h of air circulation in the building. The system is managed by a speed control unit that is synchronised with the window opener system.
Total installed electrical power: 2.4 KW​


The following results were obtained with the installation of the Eliturbo solution:

  • Excellent and continuous air mixing in the farm
  • Exchange with outdoor air
  • Animal wellbeing granted by indirect ventilation (speed on the animal not exceeding 0,2 m/s)
  • General wellbeing for the workers thanks to an improved microclimate condition and reduction of odours
  • The average indoor temperature has dropped from 34 ° C to 31 ° C (with 35 ° C outdoor temperature)
  • The average indoor relative humidity has dropped from 63% to 58% (with 65% outdoor humidity)
  • Reduction of ammonia vapor concentration, better breathing conditions both for animals and workers
  • The litter remains drier, better comfort for the animals
