SETTING NEW STANDARDS IN HUMIDIFICATION
FOR UNMATCHED PRECISION, RELIABILITY AND FLEXIBILTITY
INTEGRATED SELF-CLEANING
High performance
The NORDMANN AT4 generates sterilized, hygienic, odour-free steam. Featuring a wealth of innovative technology, it produces 5 to 130 kg of steam per hour, covering the needs of any air quality system.
Configurable
Another very useful advantage the AT4/AT4D features is its ability to configure remotely. The steam generator unit can install separately from the control unit.
This unique design makes the AT4/AT4D the choice when space is at a premium or for other individual applications.
Standard cable length is 4 metres.
The water unit contains:
- Steam cylinder
- Replenishment system
- Inlet valve
- Blowdown pump
- Self-cleaning
The control unit contains:
- Electronics
- Control panel
- Circuit breaker
- Wire terminals
Self-cleaning
The patented self-cleaning system (SC-System) prevents the formation of limescale on the electrodes and cylinder sides. It is simply removed using the blowdown pump. And for users that means maximum reliability and long service intervals.
Intelligent water management
The water regulator automatically adjusts to local water conditions, keeping water consumption to a minimum.
Easy to install
With a separate control unit, easy accessibility and external water and steam connections, the system could not be easier to install.
Building technology
The AT4 is integrated with existing building technology using the Modbus standard. If preferred, the steam humidifiers can be networked via @Link to BACnet/IP and LonWorks.
Easy to use
A big three-inch display shows steam output and easy-to-follow operating instructions. And with the user-friendly menu, entering the right settings couldn’t be simpler.
Optimum steam distribution
For normal requirements NORDMANN supplies stainless-steel steam distributor pipes as standard. If space is restricted, the MultiPipe distributor system, which drastically reduces the distance travelled by the steam, is a practical alternative.
For direct room humidification, the NORDMANN Fan4 system is the ideal choice.
