They are electronically controlled air humidification systems, mounted on walls and ceilings with “Dry Fog” technology, able to rapidly increase the air humidity level of large production environments, and it is ideal for dust suppression and to reduce static electricity. Fixed or mobile humidification system with dry fog technology is able to maintain a constant degree of humidity, large rooms such as cellars and storage areas. Moisture is an essential factor to reduce the problem of evaporation of wine stored in barriques. The wood of the barrels is a hygroscopic material that tends to release the internal humidity towards the external environment. In case of an inappropriate level of humidity in the cellar, the barrel generates an evaporation of the wine contained in it with serious losses from the economic point of view. These economic losses are caused by the decline in the product in the barrels, the reduction in quality and the costs for topping up. A standard Barrique contains 225 liters of wine, annually there is a loss of about 15% of the product for a total of 33 liters. Furthermore, with the humidity levels too low, the wooden barrels are at risk of drying out and opening the joints of the plating compromising the quality and efficiency over time.
