D.VARIABLE AIR VOLUME (VAV) CONTROL SYSTEM
(1)NORTEC offers several VAV control packages where VAV or variable duct temperature, air flow or humidity conditions require additional control flexibility.
2.STANDARD FEATURES AND BENEFITS
(1)NORTEC NHRS humidifiers can be suited for all humidity control applications. Resistive heating elements satisfy controller requirements instantaneously for rapid control with minimum deviation. NHRS units produce pure atmospheric clean steam on Potable, DI, or RO water operation. Fully variable steam output from 0 to 100% of capacity is achieved by electronic power control of the resistive heating elements. When using with deionized water(<20 micromhos) the NHRS with SSR option can control relative humidity to ± 1%. The unique design of the stainless steel cylinder ensures the process is not affected by water fill cycles.
A.INTEGRAL DRAIN WATER COOLER (DWC)
(1)NHRS has a standard internal Drain Water Cooler to meet plumbing codes by tempering the drain water below 140°F (60°C) during normal operation.
B.TWO-LINE ALPHANUMERIC LIQUID CRYSTAL DISPLAY (LCD)
(1)The NORTEC NHRS has a two line display, which provides important operating data using text for system messages and numbers. Operating status, performance data and defined parameters can be accessed and displayed. Its principle language is English, but the NHRS can display in French, on the user level.
C.AUTOMATIC SYSTEMS TEST
(1)Each time a NORTEC NHRS humidifier is started, it automatically undergoes a
D.AUTOMATIC END OF SEASON DRAIN
(1)After 3 days of no call for humidity the steam production tank will completely drain the cylinder and automatically restart upon a call for humidity. Does not apply if keep warm feature is activated.
E.AUTOMATIC DETECTION, RESPONSE, AND SYSTEM MESSAGES
(1)Operation is monitored continuously by an automatic check program. When unacceptable deviations from normal operation are detected (such as no water entering humidifier or, improper water level), the NHRS responds by taking appropriate action. Corresponding system messages are displayed on the LCD. By identifying the specific service messages, troubleshooting is simplified and problems external to the unit are more easily diagnosed. For
F.SIMPLE INSTALLATION
(1)The compact construction of the NHRS allows for a simple installation. The NHRS comes standard with key hole mounting locations, and is ready for field connection.
