Operating Parts
When steam production is required, the electronic control closes the contactor by applying an electrical voltage to the
electrodes submerged in the water.
The current flowing through the electrodes is counted by a current transformer.
When the steam production falls below the preset value, and is followed by a water level drop, the control sends a signal
to the filling electrovalve, which sends the water to the loading tray and enters the water through the water. gravity to the
cylinder.
The loading tray is equipped with two electrodes to measure the conductivity of the supply water, reference that uses
electronic control to optimize the humidifier operation, depending on the chemical characteristics of the feed water.
In the upper part of the cylinder there are two small high-level electrodes, these electrodes control that the water level
does not exceed the maximum, above this level the water is emptied through the drain tube.
The electro-discharge valve is controlled by the control, often depending on the characteristics of the feed water, in order
to maintain the optimum salt concentration inside the cylinder.
The principle of operation is unique for all humidifiers; however, it must be remembered that in humidifiers with more than
one cylinder there is a single control that sends a control signal to an interconnection card to allow the simultaneous
operation of the different cylinders, relating to the electro-valve filling connection, drain pump.
IMPORTANT CAUTION: Before connecting the water pipe to the unit, open the water source and let water run for a few
minutes to clean the pipe of any impurities that may clog the fill or drain valves, or that may cause damage to the
electrodes.
The humidifier is controlled by a system that automatically loads water into the drum, measures the conductivity of the
water and, based on the current flowing through the electrodes, adds or drains water to work with the necessary electric
current, in case the water is not adequate, lights will turn on (see table of faults) that will indicate what is the
inconvenience.
This control is also responsible for cleaning the electrodes by circulating water (at that time does not humidify).
The electrodes deteriorate with the use, the time depends on the frequency with which it is used and with the type of
water, working with water of quality as we explain later the useful life of them will be greater.
The parameters that water must have for the proper functioning of the humidifier is:
15 to 40 French Degrees 1 **
125 to 1250 micro Siemens 2 **
Be careful with treated water, because in the treatment calcium and magnesium are exchanged for sodium, this makes
the water less hard but it is not good for the conductivity of the electrodes, on the contrary you can spend them quickly and
even break them in a matter of hours .
Well water or running water is the most recommended.
Do not use demineralized water.
1 ** The French degree is used to measure the hardness of water, equivalent to 10 mg / L of calcium carbonate in water
2 ** It is called
Siemens (Electrical Conductance) , symbol (S) to the unit for the measurement of electrical Conductivity.
This unit is also called mho, reverse word of ohm or Ohm, because the conductance is the inverse of the electrical
resistance
