HACIS® ventilation system, up to 40% lower investment costs, up to 60% reduced operating costs

Poor climatic conditions in food production not only affect the quality of the food, but also promote a high level of germ contamination in the air. The resulting consequences are spoiled goods and defective production, which incur considerable costs.

The specially developed ductless HACIS® ventilation system is equipped with UV-C disinfection technology. This results in a continuous reduction in germs and prevents microbiological growth in the form of bacteria, mould or yeast.
