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.

Gas-fired steam humidifiers

CAREL’s extensive experience in the humidification business has led to the development of gaSteam, the range of gas-fired humidifiers, available in models from 45 to 450 kg/h with a temperature range of -40°C to 45°C. gaSteam runs on natural gas or LPG, and is fitted with a sophisticated built-in electronic controller that can also manage other types of gas by simply setting a number of burner calibration parameters.
The exclusive design of the heat exchanger ensures very high efficiency (94-96%) and easy maintenance. Made from stainless steel, it guarantees long life even in heavy-duty operation.
The price gap between gas and electricity makes gaSteam the ideal choice for more high load applications, where steam is required many hours a day, allowing savings in the thousands of euro per year. Continuous modulation of steam flow-rate means the appliance is also suitable for precision applications. gaSteam can operate on drinkable mains water or demineralised water (R.O.). Easy to install, it features a room-sealed combustion chamber with premix burner, and gas valve with double mechanical closing; furthermore, it is fitted with multiple safety devices and comes with ETL and CE certification (issued by TÜV-DVGW).
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.
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.

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.
