Nortec RS-Series humidifiers resolve demanding application needs. 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. 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 RS-Series 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. commercial offices hospitals computer rooms museums clean rooms schools high-tech centres printing plants 2 Nortec RS-Series 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 10 - 180 lbs/hr.
Operating advantages Precise Control All RS-Series humidifiers have an advanced controller with display for precise and efficient relative humidity control. The humidifier can be controlled by a humidistat, a relative humidity sensor or be connected to a central Building Management System (BMS) for maximum control flexibility. RS-Series Outdoor The RS-Series humidifier’s controller provides readout and adjustment of all operating parameters. The humidifier will make service adjustments automatically or trigger a shutdown while displaying the function requiring operator attention. Economy Nortec RS-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. RS-Series 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. RS-Series RS-Series self-diagnostics confirm optimal operational efficiency and reduce servicing costs. Installation Flexibility RS-Series humidifiers offer unprecedented installation flexibility. They can be configured for both small and large systems. All RS-Series humidifiers are completely packaged for installation ease. The standard drain water cooling ensures drain water does not exceed 140 F (60 C) to meet local plumbing codes. Steam distribution is easily accomplished through either the HVAC duct system or into individual areas through remote blower packs. 3
Technology Resistive Steam The resistive element humidifier offers highest accuracy performance for humidity critical applications. When using the SSR option with a high precision humidistat, the RS-Series can be accurate to 1% RH. The RS-Series is designed for use with potable or DI/RO water. For potable water applications, the unique scale collector tank option saves time and money during cleaning. The base mounted tank collects minerals and is easily removed for disposal of scale. The RS-Series is the most advanced resistive steam humidifier available. It’s high quality heating elements provide the most accurate humidity control available in the world. 4

Options SOFTWARE STEAM DISTRIBUTION Links-Series BP-Series Nortec Links-Series 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 or Johnson N2. for in space applications (remote mounted). OnLine-Series Nortec OnLine-Series is a remote interactive communication package that allows web-based 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). 6 AS-Series to distribute atmospheric steam into ducts. AM-Series for use in air handlers or ducts where short steam absorption distance is critical.
