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.

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.
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.

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
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.
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).
