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 in building the machine ensure reliability and durability in time.
The casing is made in PE, the screws are in stainless steel, and the remaining parts of the humidifier are made
in PA and PC.
The use of materials that resist the corrosive action of water and acids makes the PH a machine capable of
working in almost all the environments.
The PH combines the power of the humidification, the ease of installation, and, by operating without nozzles it is
not subject to clogging by impurities and limestone.
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
and designed: "Humidifier”.
Any other use has to be considered improper and dangerous.
