The operation of immersed electrode, industrial humidifiers is based on a very simple physical principle.
As common drinking water contains a certain quantity of dissolved mineral salts, and is consequently slightly conductive, applying a voltage to metal electrodes immersed in the water creates an electric current that heats the water until producing steam (Joule effect).
The quantity of steam produced is proportional to the electric current, which is in turn proportional to the level of water. This electric current is measured by a current transformer: by varying the level of water using a fill and drain electrovalve, the current, and consequently the steam production, can be precisely modulated.
As the steam does not carry minerals, the salt concentration in the water and therefore the conductivity increases, the water is periodically diluted and part of it is discharged through the discharge pump and replaced with supply water.
In addition, lime scale is deposited over time and covers part of the cylinder, which must be replaced or cleaned.
The principle is simple, however the development of an immersed electrode industrial humidifier that ensures safe operation and reliability over time requires careful analysis and extended testing.
Compared to the complementary immersed element heater or gas humidifiers, immersed electrode humidifiers:
- are less expensive to purchase
- operate with drinking water (not completely demineralised or softened)
- require the periodical replacement (or cleaning) of the cylinder
- feature applications without extreme requirements
