Productivity and quality of life are directly affected by
the indoor environment. People work better and feel
better in favorable surroundings. So do products and
machines! They all respond in various ways to changes
in air quality, temperature and humidity. All three
elements must be just right to maximize performance
and reliability, both in humans and equipment. Correct
humidity is critical, since too much humidity can be as
destructive as too little.
AxAir NORTEC is a world leader in state-of-the-art
humidification technology. Our focus is concentrated
exclusively on designing and building better
humidification systems. Every NORTEC NH model
has been engineered to meet the highest standards
of cost-effective, efficient performance. They are
designed for ease of installation, adaptability,
simplicity of operation, ease of maintenance and
servicing, energy efficiency, cleanliness and long-term
reliability.
NORTEC NH humidifiers offer complete application
flexibility to systems engineers, contractors and
customers. They can be integrated into central
Heating/Ventilating/Air Conditioning (HVAC) systems
or placed in specified locations for individual room
control. Models are available to serve small or large
areas with outputs of 5 - 200 lbs/hr.

Precise control
All NH Series humidifiers have an automatic system test routine, and a display window that provides readouts on operating parameters and self-diagnostic functions, including service indication. The humidifier will make service adjustments automatically or trigger a shutdown while displaying the function requiring operator attention.
NH Series humidifiers can be easily integrated with a central HVAC control system, via a computer interface, for maximum control flexibility. Humidifiers can accept command inputs from a BMS to automatically control the humidifier’s output.
Economy
NORTEC NH Series humidifiers provide lower initial installation costs for the customer. Operating costs are also reduced through efficient steam conversion rates and minimal energy losses due to low hot water drain rates.
NH humidifiers provide clean humidification, reducing air-borne contaminants and subsequent health-related employee absenteeism. Correct interior humidity levels in winter maintain comfort at lower temperatures and can reduce heating costs.
NH self-diagnostics confirm optimal operational efficiency and reduce servicing costs.
Installation Flexibility
NH Series humidifiers offer unprecedented installation flexibility. They can be configured for both small and large systems.
Steam distribution is easily accomplished through either the HVAC duct system or into individual areas through built-on or remote blower packs.
operating advantages
�
Electrode SteamThe electrode steam system produces pure uncontaminated steam with variable output through electronic power control of the electrodes. Water borne minerals remain in the cylinder and are periodically flushed out through the automatic cylinder drain. Solid mineral scale sinks to the bottom of the cylinder which, when filled with residue, is easily removed and replaced.
Resistive SteamThe resistive element humidifier offers the highest accuracy performance available. the output is variable between 0-100%. The NHDI is designed for use with DI/RO water in tight control applications. When using a high precision humidistat, the NHDI can be accurate to ±1% rh. The NHSC is designed for extreme water conditions. It incorporates the scale collector tank to save time and money during cleaning. The plastic liner ensures the scale accumulating on the tank walls will easily be removed.

ElectricSteamHumidifiers
AxAir NORTEC has been manufacturing electric steam humidifiers since 1975. Through several generations of electrode steam we are now pleased to introduce the NHTC and NHPC as our latest and most significant new product offering.
The NHTC is a powerhouse premium unit with a complete list of advanced standard features, including: a complete communication solution, the Total Controller; unmatched performance; and full graphic display to show you everything that is happening, or has happened, on your unit. All of this adds to the ease of use and low maintenance you have come to expect from Nortec cylinder based humidifiers. NORTEC, the most trusted name in Electrode Steam Humidification.

NORTEC OnLineNORTEC OnLine is a remote interactive communication package that allows satellite contacts to monitor, maintain and control a humidification center from any location worldwide using standard internet connections. This advanced software shows graphic representations of the humidifier and its key parameters (up to 75 functions).
NORTEC LINKSNORTEC Links offers monitoring and control allowing humidifier(s) to communicate to your Building Management System (BMS). The controller is factory installed and is located internally to the humidifier. Simply specify at time of order what operating protocol you are using – BACnet IP, BACnet MSTP, LonWorks, Modbus or Jonhson N2.
