The operation of immersed electrode 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 (Joule effect) until boiling, thus producing steam.
The quantity of steam produced is proportional to the electric current, which is in turn proportional to the water level.
This electric current is measured by a current transformer: by varying the level of water using a fill solenoid valve and due to the evaporation process, the current, and consequently steam production, can be modulated. Due to evaporation, the level of water decreases and must therefore be topped up. As the steam produced does not carry mineral salts, the salt concentration in the water and therefore the conductivity increases, and has to be periodically diluted by draining part of it using the drain pump and replacing it with new water.
In addition, scale forms 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 humidifier that ensures safe operation and reliability over time requires careful analysis and extended testing.
Compared to electric heater or gas-fired humidifiers, immersed electrode humidifiers:
are less expensive to purchase;
operate with drinking water (not completely demineralised or softened);
require periodical replacement (or cleaning) of the cylinder;
feature modulation suitable for comfort or industrial applications, without extreme requirements.
CAREL has been manufacturing immersed electrode humidifiers since the 1970s and can draw benefit from its know-how in the field of electronic controllers: precision control, reliable electronics and sophisticated and complete control software.
The CAREL solutions for immersed electrode humidifiers are humiSteam and compactSteam.
Atomisers – evaporative cooling
This product is available in CAREL CPQ, the sizing and selection tool that lets you independently find the right CAREL solutions for you, download the related documentation, receive support, and generate quotes and orders.
"Evaporative Cooling" is the process in which water cools the air through evaporation. For this to happen spontaneously, without the contribution of external energy, the water must be atomised in the air as very fine water droplets which, having a lower surface tension than the surrounding air, evaporate into the air.
Why does the air cool down?
No contribution of external energy is necessary, however, owing to its nature, the water evaporation process requires a certain amount of energy. This energy is removed from the air itself which, in order to absorb the water must release sensible heat, thus lowering its own temperature.
Every kilogram of water that evaporates absorbs 0.69 kW of heat from the air. This is how the dual humidification and cooling effect of the air is obtained through the Evaporative Cooling process, which in many air handling applications represent two desired effects.
Energy Saving
The rapid development of evaporative cooling in HVAC applications is surely due to its very low energy impact. If we compare the cost for energy regarding Evaporative Cooling with that of other types of air transformations (e.g. humidification with steam emission or air cooling via chiller), it can be seen that the energy saving is considerable. The only energy required is for water pressurisation, which is sent to the atomiser nozzles by a pump. Consumption is about 4 to 8 W for every l/h of atomised water. Optimist atomisers CAREL supplies a complete range of products that make use of the principles of evaporative cooling and all its advantages. The standard composition of these products is:
- cabinet, containing the pump for pressurising the water, an inverter and an electronic controller for modulating the production of atomised water instant by instant;
- atomiser nozzles, able to atomise the water into very fine water droplets (in the order of a few hundredths of a millimetre), extending the heat exchange surfaces.
- distribution system, composed of stainless steel manifolds, atomiser nozzles and drain valves, in order to guarantee emptying.

humiDisk is a small yet sturdy humidifier that uses a spinning disk to atomise water and transform it into millions of very small droplets that, blown by a built-in fan, are introduced into the environment, where they evaporate, humidifying and cooling the air.
Very low power consumption
humiDisk is a simple, economic and easy to maintain humidification system, with an energy consumption of just 220 W for 6.5 kg/h of capacity (31 W for the 1.0 kg/h model).
Guaranteed hygiene
The water tank inside the humiDisk contains just 0.055 litres of water, which is atomised, at maximum capacity, in just 30s for the 6.5 kg/h model and 3 minutes for the 1 kg/h model. The water in the tank is therefore changed very rapidly, meaning the humidifier substantially works with non-stagnant running water, so as to guarantee the best hygiene conditions.
Adjustable capacity (humiDisk65 only)
Operation of humiDisk65 controlled by an electronic board fitted with a trimmer for setting humidifier capacity, from 1.1 to 6.5 kg/h, making it suitable for all applications.
Automatic washing cycles (humiDisk65 only)
The board, as well as managing normal unit operation, also performs a tank washing cycle when starting the unit, and an emptying cycle when humidification is no longer required. This avoids having stagnant water inside the unit.
Important: to ensure a higher level of hygiene, when using the CAREL electrical control panels, the humidifier also washes the water tank at the start of each humidification cycle.
Water used
humiDisk can operate on both mains water or treated water. The quantity and quality of the minerals dissolved in the water affect the frequency of the routine maintenance operations and the amount of dust generated. For best operation, use demineralised water (do not use softened water, as this does not reduce the content of minerals dissolved in the water). In any case, observe the requirements of UNI8884 standard "Characteristics and treatment of the water in cooling and humidification circuits", according to which the main characteristics of the water are conductivity < 100 μS/cm and total hardness <5 °fH (50 ppm CaCO3). Similar requirements are also specified in standards VDI6022, VDI3803.
