1.7 Applications
In industry, the PH humidifier is installed in premises where a certain level of humidity must be
maintained, for example in cold storage rooms for fruit and vegetables, in curing warehouses, in the
paper and tobacco industries and in textile factories.
In agriculture it is used to humidify mushroom- and greenhouses, and for pest control treatments.
In livestock farming, it is used to maintain humidity in enclosures and installations that spray
disinfectants or other solutions into the environment.
The materials used guarantee reliability and durability, they are not affected by the corrosive action of
water and acids and make the PH a machine suitable for working even in very critical environments.
The PH combines humidification capacity with ease of installation and handling and, as it operates
without nozzles, is not subject to clogging due to impurities and limescale.
The water pressure required is that of the water mains (2 to 4 atm).
This machine must only be used for the purpose
for which it was designed:
Room humidification
All other uses are improper and potentially dangerous.
