Pressurised water humidifiers exploit the potential energy transferred to the water by a special volumetric pump in the form of high pressure (generally 70 bars), so as to achieve very fine atomisation through special nozzles.
The most common application of these humidifiers is in AHUs, where the pressurised water distribution system is installed. In industrial environments for processing wood or paper, or in the textiles industry, systems are often used to distribute atomised water directly into the rooms. As well as humidity control, pressurised water atomisers are the best solution for fully exploiting the potential offeredby evaporative cooling, both direct and indirect, inside AHUs or in rooms, as in the case of industrial facilities and large public spaces, such as metropolitan railway stations and airports.
One crucial aspect is the hygiene that pressurised water humidifiers must guarantee in the application where they are used. Management of washing cycles, the materials used and the configuration of the atomised water distribution system are the main features that guarantee CAREL humidifiers comply with the strictest hygiene regulations in force (VDI6022). humiFog multizone represents the new generation in high pressure atomised water humidifiers.
A volumetric pump sends water at high pressure to a distribution system made up of nozzles that atomise the water into very fine droplets, which can be absorbed by the air in a very short space.
Energy saving
The only energy humiFog consumes is used to power the water pump, just 4 watts for every l/h of capacity. Cooling in summer is provided by lowering air enthalpy, while humidification in winter has the advantage of being able to use thermal energy at low temperature. Power consumption is thus minimised. In addition, an inverter is used to modulate pump speed, meaning both more precise control and even lower power consumption.

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.

Compressed air water atomisers

Compressed air humidifiers are the ideal humidification solution whenever a compressed air supply is available, as is the case in many industrial applications, even if humidification systems are often fitted with a dedicated air compressor. The humidifier essentially consists of a cabinet fitted with electronic controller that, using two independent connection pipe networks, supplies the spray nozzles with compressed air and water at the ideal pressure for instant operating conditions.
The units can be installed inside an AHU or directly in the room where humidity needs to be controlled. The greatest advantage of these atomisers is the minute dimensions of the droplets produced and their thorough mixing in the compressed air that, due to its speed, distributes the aerosol in the room and consequently allows quick absorption. These units can therefore be readily used for direct cooling in rooms, and are ideal for the textile industry, wood and paper processing, and storerooms, where there is almost always a supply of compressed air.
mc multizone features an electronic controller that manages the supply of water and compressed air to the nozzles.
Water atomisation is managed by an external control signal or, in the case of stand-alone control, so as to maintain the humidity/temperature set point. The unit also manages a series of automatic cycles, such as nozzle cleaning and washing.
The system has the ability to control humidity independently in multiple zones (rooms, AHUs, cold rooms) using a main/secondary layout. The layout has one master and multiple clients (up to 5) connected in a pLAN. The master is fitted with a display for accessing the readings, viewing the status and messages on the master and clients. The clients have their own internal controller and can be set to continue operating even if connection to the master is interrupted.
Ultrasonic humidifiers

The new humiSonic range comprises two versions, meeting the needs of all applications: humiSonic compact, small enough to be installed on a fan coil, and humiSonic direct, for room distribution.
Ultrasonic humidifiers feature a small water storage tank and piezoelectric transducers installed at the bottom of the tank. The surface of the transducer vibrates at very high speed (1.65 million times a second), a speed that does not allow the water to move due to its inertial mass. During the negative amplitude of the transducer cycle, a sudden void is created that brings about the production of microscopic bubbles, which are pushed to the surface of the water during the positive amplitude of the cycle. This effect is called cavitation.
During this process, the resulting intersecting sound waves created directly underneath the surface of the water cause very small droplets of water to separate, forming a fine mist of vapour that is immediately absorbed by the flow of air.
This ultrasound technology applied to CAREL air humidification solutions is efficient, reliable and versatile:
- efficient, as ultrasonic humidifiers guarantee energy savings of 90% when compared to ordinary steam generators;
- reliable, as humiSonic is guaranteed for 10,000 operating hours when running on demineralised water;
- versatile, thanks to the size of the droplets produced (average diameter of 5 µm).This fundamental characteristic guarantees very fast absorption of the atomised water in the room or duct, avoiding possible condensation.
Immersed electrode humidifiers

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.
