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.

Dehumidifiers
Dehumidification is vital for many industrial processes, and desiccant is considered the most effective method. Most dehumidifiers look the same, but what sets them apart is the desiccant wheel – the heart of the system. This critical dehumidifier component efficiently removes moisture from the air.
Steam distribution systems

These accessories are available for the humiSteam, compactSteam, heaterSteam and gaSteam humidifiers.
The CAREL range of accessories for isothermal humidifiers have been especially developed to allow the creation of humidification systems that are complete and suitable for all types of application.
The fundamental idea is to guarantee optimum operation of the humidification system by providing the installer, maintenance personnel and user all the auxiliary components that simplify installation, steam distribution, operation and control of the humidifier.
The new high-efficiency linear steam distributors are the first to feature thermal insulation so as to reduce condensation in the ducting.
This innovation brings extremely positive results in terms of energy efficiency: tests have in fact shown a reduction of at least 20% in condensation when compared to standard steam distributors.

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.

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.
