1 NH Series Electric Steam Humidifiers Designed for installation flexibility while maintaining precise humidification control

2 NORTEC NH Series humidifiers resolve demanding application needs. commercial offices hospitals computer rooms museums clean rooms schools high-tech centres printing plants 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 lbs/hr. 2

3 operating advantages 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.

4 technology AxAir NORTEC has been manufacturing electric steam humidifiers since 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. Electrode Steam The 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. NHTC NH Series Electric Steam Humidifiers Resistive Steam The 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. NHSC NHDI

5 NHTC NHPC The new NHTC is the world s most advanced electrode steam humidifier available. The new Total Controller allows for easy monitoring and control of humidifier(s) from any building management system (BMS) from any location worldwide using a standard internet connection. The NHDI/NHSC is the most advanced resistive steam humidifier when it comes to very pure or extreme water conditions. It s built-in solid state relays and high quality heating elements provide the most accurate humidity control available in the world.

6 options Steam Distributor Systems Nortec offers flexible steam distribution choices to satisfy a wide range of requirements: Stainless Steel Steam Distributors to distribute atmospheric steam into ducts. Independant Blower Packs in space applications (built-on or remote mounted). SAMe Short Absorption Manifold for use in air handlers or ducts where short steam absorption distance is critical. Atmospheric steam distributor Blower pack SAM-e Short Absorption Manifold NORTEC LINKS NORTEC 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. NORTEC OnLine NORTEC 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). Customer Communication through the internet or .
