Immersed electrode humidifier
Option
Connexion humidificateur: 1” F
Supply water
The humidifier must be supplied with mains water having the following features:
 pressure between 0.1 and 0.8 Mpa (1 – 8 bar)

temperature between 1 and 40°C
Do not use:
 water treated with softeners: it can corrode the electrodes and form foam with possible faults/
malfunctionings

pit, industrial or potentially polluted (chemically or bacteriologically) water
 disinfectants or anti-corrosive substances mixed with water, as potentially irritating
Supplying the humidifier with water treated with reverse osmosis filtering system gives the following
advantages:

reduces limescale deposits

reduces energy consumptions
 reduces maintenance costs

increases humidifier duration
Check that the filter guarantees a water flow rate higher than the flow rate of the installed humidifier.

Drainage water
It can reach a temperature of 100°C.
It contains the same substances of the supply water but in higher concentration.
As it is not toxic, it can be disposed of with white waters.
