1.7 Applications
In the industrial field, the machine is installed in places where it is necessary to maintain a certain humidity
level, for example in fruits and vegetable refrigerating rooms, in aging warehouses, in the paper and tobacco
industries, and in textile companies.
In agriculture the machine is used to humidify greenhouses and mushroom farms, and for disinfectant
treatments.
In animal husbandry the machine is used to cool or nebulize disinfectant or other solutions in the environment.
The materials used ensure reliability and durability over time.
The machine’s body and components are in AISI 304 stainless steel, the screws in stainless steel, the humidifier
components are in PA PC and ABS.
The water pressure required is the same as in the water supply network (between 2 and 4 atm).
This device must be used only for the functions for which it was intended:
- Adiabatic cooler and/or humidifier
- Air circulator
Any other use has to be considered improper and therefore dangerous.
