Description

humiSonic Direct is an ultrasonic humidifier designed for direct room distribution. The ultrasonic technology enables humidification with extremely fine aerosol particles (1–5 μm), as the process generates a fine mist that is directly absorbed by the airflow. This characteristic ensures rapid evaporation of the atomised water particles and prevents unwanted condensation.

humiSonic provides a high level of control for temperature and humidity regulation (±1% from setpoint). The unit has low power consumption and provides maximum energy savings compared with steam humidification. Combined with CAREL’s market-leading technology, the ultrasonic solution is both efficient, reliable and versatile.

The product is equipped with a flexible controller and can operate as a stand-alone unit, be connected to a humidistat or integrated into a higher-level control system, such as a BMS. External control is available via either Modbus RTU (standard) or an analogue control signal (option). A wide range of accessories enables simplified and reliable operation through automation, adaptation to specific system requirements and scalability through master/sub-unit configuration.

 

humiSonic is suitable for:

• Cleanrooms, hospitals and pharmaceutical production environments.
• Industrial applications – textile, printing and paper industries.
• Residential and public environments – shopping centres, offices, museums and libraries.
• Data centres, electronics production, cold rooms or other evaporative cooling applications.

 

humiSonic is also available in a version for duct distribution. For more information, see humiSonic Ventilation.

Accessories
A complete range of accessories is available for the product, such as temperature, humidity, air quality or combined sensors (temperature and humidity) for room or duct installation, available in versions for digital (RS485) or analogue (0–10 V or 4–20 mA) connection. Please contact our sales team for specific requirements. Examples of additional options include:

• Control board for connection of control panel or sensor.
• Control panel (LCD terminal).
• Components for overflow monitoring (FLOS).
• Flow sensor (TAM).

 

Replacement components

• Piezoelectric transducer (service interval: 10,000 hours)


Installation
humiSonic Direct is designed for horizontal or vertical/wall mounting. The unit has an integrated fan section for distribution of water particles and is installed in the room where humidification and cooling are required. To ensure correct functionality, the unit should be connected to a water treatment system (WTS), which demineralises the water through reverse osmosis. Direct connection to the existing water supply is not recommended. Components required for connection to the water supply are not included in the delivery. The unit can be equipped with a control board (accessory) for external regulation or with an LCD terminal (accessory), which can be installed up to 200 m from the humidifier via a shielded modular cable. For further details regarding installation requirements, electrical and control connections, and operating configuration, please refer to the product’s installation and user manual below (PDF format, English).

 

Operation / Maintenance
Integrated functions such as periodic flushing cycles and complete water drainage, combined with high-quality stainless-steel components and a non-recirculating water design, contribute to reliable operation and simplified maintenance. The product should be complemented with a water treatment system (WTS) to ensure a component service life of 10,000 hours. The service interval depends directly on the quality of the supply water and the operating time of the unit. Maintenance must only be carried out by qualified personnel.
