    On NHTC and NHPC models the drain automatically empties the steam cylinder if it is not operated for three days. Solid mineral scale sinks to the bottom of the cylinder which, when filled with residue, is easily removed and replaced.
  • Page 12 When supply water conductivity is extremely high (requiring substantially more drains), the NHTC/NHPC will see the pattern developing in cycles stored in memory. It will then initiate additional drains to adjust the contained water conductivity.

    B. NH CAPACITY ADJUSTMENT Each NORTEC NH Series humidifier is rated at its maximum output capacity. By means of the alphanumeric display and keypad on the NHTC/NHPC, the humidifiers can be adjusted to obtain an output between 20% and 100% of its rated capacity.

    It is important to note that the drain rate shown includes the make-up water, mixed with the drain water, which tempers the drain water to 140°F (60°C) or less. The electrode steam process provides optimum efficiency because all resistance to current passage is converted to usable energy.

    1. HUMIDITY A. ESTIMATING THE HUMIDIFICATION LOAD Note: The humidification load can easily be calculated by using Nortec’s Humidification Engineering and Load-sizing Program (HELP). The softward can be downloaded at www.humidity.com (1) Relative humidity is the percentage of moisture in the volume of air at a given temperature, compared to the maximum amount of moisture that the volume of air can hold at the same temperature and atmospheric pressure.

    Table 1. Outdoor/Indoor Relative Humidity Conversion Chart 100% -20° -10° -5° Chart shows what the residual indoor RH would be at 70°F under varying outdoor conditions if a proper humidification system were not installed in the building. Studies indicate that the recommended RH should be between 40% and 60% for optimum benefits to the occupants.

    (3) Using the natural ventilation method requires knowing the volume of the humidified space and the type of construction. A tightly constructed building will have a least one air change per hour. A loosely constructed building will have at least one and one half changes per hour, and this same building with a large a amount of incoming or exiting traffic will have at least two air changes per hour.

  • Page 36: Steam Absorption And Distribution

    A. VARIABLES THAT AFFECT ABSORPTION DISTANCES (1) This manual will help in the design of a steam distribution system to provide the optimum performance from the humidifier and absorption of steam within the duct system. (2) Experience has shown that absorption of steam is affected primarily by the psychrometric conditions of the air based on how much residual capacity at a given air volume and temperature exist to hold the moisture being introduced.

  • Page 37: Figure 3. Steam Distributor Location

    Table 9. Typical Absorption Distances, Single Distributor, 100 lbs/hr Humidifier °F °C % RH 1000 1000 1000 2000 5000 (V) = Velocity at distributor location (D) = Absorption distance (visible steam) NOTE: This chart is for reference only; multiple distributors can reduce absorption distances.

  • Page 38: Calculating The Down Stream Humidity Level

    If the load calculation of this system requires a 100 lbs/hr unit, then due to the above possible conditions, the project requires a modulating high limit humidistat to limit the humidifier output to a maximum of 74 lbs/hr and maintain 80% rh. Example 2: Humidification load is 30 lbs/hr.

  • Page 39: Control Of Duct Or Plenum Saturation

    Maximum capacity of the NHTC/NHPC humidifier can be limited through the keypad. C. CONTROL OF DUCT OR PLENUM SATURATION (1) NORTEC always recommends the use of a high limit humidistat set at 85% relative humidity in combination with an air-proving switch to assure air movement. Both of these controls are wired in series across the primary control terminals of the humidifiers so that should either of these conditions not be satisfied the humidifiers cannot operate.

  • Page 40: Steam Runs And Condesnate Returns

    (2) Guidelines for installation are: (a) Locate humidifier as close as possible to the duct system. (b) NORTEC steam hose should only be used on short steam runs below 10 feet. (c) Minimize elbows and turns. (d) Ensure that no condensate produced in the steam line will remain trapped. Steam naturally flows upward and condensate naturally flows downward.

  • Page 41: Table 11. Steam Line Material

    Table 13. Recommended Condensate Line at Distributor(s) Dispersion Method Condensate Hose 1 x Steam Distributor d" NORTEC 1328840 3 x Steam Distributor* d" NORTEC 1328840 NOTE: When using more than one distributor, the condensate line should be trapped before it is joined together.

  • Page 42: Condensate Return

    NOTES: 1. This table gives the maximum recommended length of steam run by unit size. 2. The use of any steam line other than copper or NORTEC supplied steam hose will void the warranty and may adversely effect the operation of the humidifier.

  • Page 43: Figure 7. Steam Line Connection

    (2) Use vertical condensate leg of distributor only. Do not over-tighten clamp. (3) Drip stations on steam mains must be located at all low points in the system, at each elevation change and or directional change. (4) Horizontal runs of steam must have a 2"...
  • Page 44 (7) Vertical drop of the drip station should be 1.5 times the diameter of the steam main but no less then 12". (8) Install the P trap at the botom of the drip station. The P trap height is to be a minimum of 6 inches or 2 “...

    4. STEAM DISTRIBUTORS (ASD, BSD, CSD) A. STEAM DISTRIBUTORS (1) NORTEC’s steam distributors, in use for over twenty years, are a proven design to suit applications for the introduction of atmospheric steam. (2) Features and benefits of steam distributors are: (a) Expanded diameter of tube to reduce steam velocity and the potential for condensate carryover into the duct.

  • Page 46: Distributor Locations And Mounting

    (c) CSD: 115 lbs/hr (45 kg/hr) C. DISTRIBUTOR LOCATIONS AND MOUNTING (1) NORTEC distributors can be mounted in air handlers, supply air ducts or return air ducts. Return air ducts should only be considered if all of the return air enters the building again and is not exhausted by the air handling device.

  • Page 48: Location Of Steam Distributors Within An Air Handler

    UNLESS YOU KNOW THE EXACT ABORPTION DISTANCE REQUIRED FOR THE STEAM ABSORPTION INTO THE AIR STREAM, THE DISTRIBUTOR SHOULD BE LOCATED AT LEAST 8-10 FT (2-3 M) AWAY FROM ANY OBSTACLE IT MAY CONDENSE ON (ELBOW, DIFFUSER, FILTER, ETC.) (2) Duct vertical clearance requirements for standard steam distributors are as follows: (a) ASD - 8 in.

  • Page 49: Typical Applications

    The manufacturer recommends the appropriate distance modification factors when filters or humidification sensors are installed downstream. For applications that are outside of the Nomogram’s range, please consult a NORTEC representative. G. TYPICAL APPLICATIONS (1) Representations of typical applications are found in Figure 15 and Figure 16.

    5. SHORT ABSORPTION MANIFOLD (SAM-e) A. GENERAL (1) NORTEC’s best performing steam absorption system for use in Air Handling Units and duct systems where short steam absorption distance is critical. (2) The SAM-e, Figure 17, distributes clean steam, precisely controlled, uniformly into the entire air stream, void of any condensate spray.

  • Page 51: Determining The Steam Absorption Distance

    (5) The features of the short absorption manifold are: (a) Inlets/Outlets located on same side, one access point required. (b) All stainless steel distributors and nozzles ensure permanent bond. (c) Stainless steel header with rubber grommet seals for easy installation of distribution tubes.

  • Page 52: Static Air Pressure

    2000 (1020) 0.12 (0.30) D. CONDENSATE LOSSES (1) The SAM-e will condense some of the steam generated by the NORTEC humidifiers. To compensate for this loss in capacity, we must increase the calculated humidification load accordingly. Refer to Table 16.
