The particular type of installation, the only one of its kind in the world, ensures a highly efficient system and low energy consumption, thanks both to the natural structure of the cells and the cooling units installed in them. The air chillers are equipped with electronic fans with very high output and low electrical consumption. Their finned batteries provide vast surface area to guarantee optimum conservation of the product in terms of both temperature and humidity.
