AIRWIN - The art of humidification


AIRWIN product groups

The AIRWIN portfolio, which is constantly further developed, includes ultrasonic humidifiers for a wide range of applications. The modular design of the series and the flexible possibilities of use offer a wide spectrum with humidification capacities ranging from 0.5 kg/h to 25.2 kg/h. The excellent controllability does not only recommend these devices for applications such as measuring and testing laboratories, but also for use in air ducts. In the context of sustainability of fresh produce such as fruit and vegetables, humidification plays a central role. The AIRWIN portfolio is rounded off by control and monitoring units.

Duct air humidification

Central air humidification is implemented with the NKBD 3.1 and NKBD series. The humidification capacities range from 3.6 kg/h up to 25.2 kg/h. For larger requirements, humidification groups consisting of several duct humidifiers can be used. A positive effect of adiabatic humidification according to the ultrasonic principle is the cooling of the air.


The NKBD-6…42/3.1 series has a performance range from 3.6 to 25.2 kg/h humidification capacity. The ultrasonic humidifier for installation in the air duct is already equipped with the control board PCB AIRWIN 3.1 and offers an extended range of functions such as improved thermal management, MODBUS RTU, operating and collective error messages via potential-free connections, as well as the improved hygiene management AquaDrain plus.

The AIRWIN series NKBD is made of hygienically impeccable stainless steel and equipped with the cyclic drainage system AquaDrain. The NKBD is applied in air ducts. Output ranges from 3.60 kg/h (NKBD-6) to 25.2 kg/h (NKBD-42).

The proportional control of the ultrasonic humidifier is operated with standard control signals. For high output requirements, several NKBDs can be connected and combined to form humidifying groups and can therefore be used in a flexible way.

Accessories - Duct air humidification

The accessories for the NKBD can be installed easily and quickly, even when retrofitted. The mounting frame can take up several humidifiers.

Direct room air humidification

The series RB/P and RB/P-D are designed for direct room air humidification. With an available humidification capacity ranging from 1 kg/h to 8 kg/h and an integrated cross flow fan, they are the ideal solution for air conditioning with humidity inside a room.

The RB/P-D is equipped with the cyclic drainage system AquaDrain ensuring especially hygienic operation.


This series is designed for direct humidification of the room air. Wherever humidification via the ventilation system is not possible or there is no ventilation system, decentralized devices must be used. Prominent examples are climatic chambers or in offices. The humidifiers with the addition 3.1 are based on the PCB AIRWIN 3.1 control board and offer all the relevant functions, such as status messages, MODBUS RTU, improved thermal management and AquaDrain plus.

For humidification outputs of more than 2kg/h, the series UB-8 and UB-12/18/24 are available. All universal humidifiers are equipped with the cyclic drainage system AquaDrain.


The DRC was developed for applications under harsh environmental conditions. The component selection is based on the protection class of IP54 or higher. The DRC can be used directly in the room or work in bypass. The electronics are separated from the fluid area so that even highly humid air is not an issue. The DRC already relies on PCB AIRWIN 3.1 and is equipped with AquaDrain plus. The optional Bypass kit is required for operation in bypass.


The UB-1...4/3.1 series is based on the control board generation PCB AIRWIN 3.1 with some additional functions, such as improved thermal management, revised solenoid valve control, MODBUS RTU and the hygiene management AquaDrain plus. The functionality remains as usual, in order to be able to use the multitude of functions, a new connector is used. If you want to work with a remote control, you can purchase it as an option and connect it directly to the UB-1...4/3.1.

UB-1…4/3.1 CT

The UB-1...4/CT/3.1 series uses the PCB AIRWIN 3.1 PCB and has an integrated continuous controller. The connection of a humidity sensor directly to the universal humidifier is sufficient to set up a compact and precise humidification system. The aerosol outlet pipes enable the targeted guidance and distribution of the humidified air. The series is equipped with the AquaDrain plus hygiene management system.

Humidification of smallest quantities

The humidifier KMB for smallest quantities with a humidification output of 0.5 kg/h is the smallest humidifier of the AIRWIN group. Control ranges from 0-10 V. KMB is mainly used for special applications in local humidification in connection with production processes or in air-conditioning or measuring chambers. A great advantage of the KMB is its compactness.


Series expires, successor device in Q3/2022

The compact humidifier for smallest quantities is used for humidification outputs up to 0.5 kg/h. Common applications include small volumes such as measuring or laboratory cabinets. Optionally, the KMB, which is designed to work with an existing airflow, can also be equipped also with a fan module which allows for spot humidification without existing ventilation. The precise control is operated via a 0-10 V control signal.

Accessories - Smallest quantity humidification

Optional extensions for smallest quantity humidification are the AquaDrain module for cyclic drainage of the integrated fluid tank and the fan module, which can simply be attached to the KMB.

Control and monitoring

For the control and monitoring of ultrasonic humidifiers, AIRWIN provides control cabinets with integrated continuous controllers for continuous proportional control. Humidity sensors which can be connected to the continuous controller and hygrostats for single-stage and two-stage operation are also available.


The control cabinets SUR/P and SUR/PT come with the continuous controller BO-CT1. By evaluating the reference variable relative humidity, connected humidifiers may be controlled continuously proportionally.

The control cabinet SUR/PT is also equipped with a power transformer which is responsible for the power supply of the humidifier.
