The higher the current being passed between the electrodes, the greater the quantity of steam that is produced.
To modulate the rate of steam production, this system shall vary the level of water within the cylinder, thereby increasing
the immersion level of the electrodes and the current being passed between them. The more conducting area that is
available to pass current between the electrodes, the larger the amount of steam that shall be produced.
Modulated by the controller, the water level is varied so that the level of steam being produced ensures that the room
humidity set-point is continually maintained within a tight tolerance.

into the bottle feed. This sensor shall determine the conductivity level of the supply water and by using an algorithm
embedded in the software, determines the frequency that the bottle should be drained.
Example: (Optimised Lifetime with High Water Conductivity Supply)
As liquid water is boiled off into steam, mineral deposits are left in solution increasing the conductivity of the water.
To counter this, the intelligent software increases the frequency of drain meaning that the replenishing supply water

that they can modulate independently of the suction line temperature. This unique feature allows the controller to raise
