XT electrode steam humidifiers use hard or softened supply water. Water conductivity must be in the range of 125 to 1250 μS/cm (roughly equivalent to 3.4 to 36.3 grains per gallon). See “Supply water considerations” on Page 44. Damage caused by chloride corrosion is not covered by your DRI-STEEM warranty. Demineralized, deionized, and reverse-osmosis water cannot be used, because they are not conductive enough for electrode steam humidifiers. Heated supply water cannot be used, because unheated supply water is required for drain water tempering. 1BHF t %3*45&&. 95 &MFDUSPEF 4UFBN )VNJEJGJFS *OTUBMMBUJPO 0QFSBUJPO BOE .BJOUFOBODF .BOVBM Overview 1SPEVDU PWFSWJFX Dispersion options In addition to Rapid-sorb dispersion shown in Figure 2-2, the duct dispersion options below and the open space dispersion options in Figure 3-3 are available for XT humidifiers.

A safety earth grounding system that meets national, state, and local electrical codes is required. The ground connection must be made with solid metal-to-metal connections. Ground wire should be the same size as power wiring. Electrical noise can produce undesirable effects on electronic control circuits, which affects controllability. Electrical noise is generated by electrical equipment such as inductive loads, electric motors, solenoid coils, welding machinery, or fluorescent light circuits.

See the recommendations below and Figure 22-1. Note: DRI-STEEM recommends that you do not interchange room and duct humidity devices. Room humidity devices are calibrated with zero or little airflow, whereas duct humidity devices require air passing across them. Recommended humidity control (transmitter/humidistat) locations: A Ideal. Ensures the best uniform mix of dry and moist air with stable temperature control. B Acceptable, but room environment can affect controllability, such as when sensor is too close to air grilles, registers, or heat radiation from room lighting. C Acceptable. Provides uniform mixture of dry and moist air. If extended time lag exists between humidity generation and sensing, extend sampling time. D Acceptable (behind wall or partition) for sampling entire room if sensor is near an air exhaust return outlet. Typical placement for sampling a critical area. & Not acceptable. These locations might not represent actual overall conditions in the space. F Not acceptable. Do not place sensors near windows, door passageways, or areas of stagnant airflow. Recommended safety (airflow and high limit) sensor location: G Best sensing location for high limit humidistat or humidity sensor and airflow proving switch.

Field-supplied hose may have shorter life and may cause foaming in the cylinder resulting in condensate discharge at the dispersion assembly. Do not use steam hose for outdoor applications. † For XT-150 and XT-200, capacities listed are the maximum steam carrying capacity per tube or pipe attached to each cylinder, with separate steam piping from each cylinder to the connection on the dispersion device. See Figure 35-1. †† DRI-STEEM typically recommends 10' (3 m) maximum steam hose length pitched at 2"/ft (15%). Steam hose has a tendency to sag if it is not supported for its full length. Sagging leads to collecting condensate and system pressure issues. Hard pipe or tubing is less prone to sagging and can allow for 1/8"/ft (1%) pitch minimum with longer runs. ††† Developed length equals measured length plus 50% of measured length to account for pipe fittings. mc_091410_1050-XT 1BHF t %3*45&&. 95 &MFDUSPEF 4UFBN )VNJEJGJFS *OTUBMMBUJPO 0QFSBUJPO BOE .BJOUFOBODF .BOVBM Installation % J T Q F S T J P O *OUFSDPOOFDUJOH QJQJOH SFRVJSFNFOUT Connecting to humidifier with steam hose t 4VQQPSUTUFBNIPTFGPSJUTGVMMMFOHUIUPQSFWFOUTBHTPSMPX spots: – For single dispersion tube without condensate drain, maintain BNJOJNVNQJUDIPGGU UPXBSEUIFTUFBNDZMJOEFS – For dispersion devices with condensate drain, maintain a NJOJNVNQJUDIPGGU UPXBSEUIFEJTQFSTJPOEFWJDF For hard pipe connections, see “Connecting to humidifier with tubing or pipe” on Page 31. t 6TF%3*45&&.TUFBNIPTF0UIFSNBOVGBDUVSFSTPGTUFBN hose may use unacceptable release agents or material mixes that can affect humidifier system performance adversely.

When the call for humidity is satisfied, the controller opens the humidifier contactor but keeps the XTSB running for a preset amount of time, which is adjustable via the Vapor-logic4 Setup menu. As steam is discharged from the XTSB, it quickly cools and turns to a visible fog that is lighter than air. As this fog is carried away from the XTSB by the airstream, it tends to rise toward the ceiling. If the fog contacts solid surfaces (columns, beams, ceiling, pipes, etc.) before it disappears, it can condense and drip. The greater the space relative humidity, the further the fog will rise, spread, and throw. Table 39-1 lists the maximum rise, spread, and throw non-wetting distances for XT humidifiers with XTSBs.

Output consistency and efficiency %3*45&&.TDPOUSPMMFSBMHPSJUINPQUJNJ[FTTUFBNPVUQVU consistency, water efficiency, and energy efficiency by managing the frequency and duration of drain and fill events for the supply water being used. The frequency and duration of drain and fill events is proportional to the conductivity of the supply water. Less conductive supply water requires less frequent drain and fill events, resulting in more consistent steam output and more efficient use of energy and water. Cylinder life Hard water scale coats the electrodes and eventually requires a cylinder replacement. The harder the water, the more frequent the need for a new cylinder. Softened water is an option in some facilities. Because softened water ions stay in solution to much higher concentrations than hard water ions, softened water does not coat the electrodes nearly as much as hard water, potentially extending cylinder life. There are benefits and tradeoffs to consider when the application allows a choice between hard and softened water: t 5IFCFOFGJUPGTPGUFOFEXBUFSJTMPOHFSDZMJOEFSMJGFEFQFOEJOH on water chemistry), but the trade-off is more frequent drain and fill events. t 5IFCFOFGJUPGIBSEXBUFSJTMFTTGSFRVFOUESBJOBOEGJMMFWFOUTCVU may result in more frequent cylinder replacement.

Controller receives a call for humidity Figure 46-1: XT humidifier principle of operation 4 When the RH level in the humidified space drops below set point, the humidifier controller receives a call for humidity and calculates a corresponding electrical current. The controller closes the contactor, which energizes the electrodes. If there is not enough water in the steam cylinder, the fill valve opens and water enters the steam cylinder. 2. Energized electrodes boil water into steam 1 2 3 When the water level in the steam cylinder rises to touch the electrodes, electrical current flows through the water between the electrodes. Electrical resistance in the water causes the water to heat up and boil into steam. The steam flows through the steam outlet and through steam hose, tubing, or piping to the XTSB or dispersion assembly, where it is discharged into the airstream. 3. Electrical current increases to meet demand 5 (fill) As the amount of water covering the electrodes increases, current flow increases. The fill valve remains open until the amperage increases to 10 percent above the current corresponding to the demand signal. Then the fill valve closes, and the water boils into steam. 5 (drain) mc_111610_0455 4. Water continues to boil into steam OM-7641X Staging multiple XT humidifiers Up to four XT humidifiers can be staged to operate in sequence. In a sequenced application, one control input signal is divided into user-selectable control input signals for the connected humidifiers. See the Vapor-logic4 Installation and Operation Manual for instructions on staging multiple XT humidifiers. As the water boils into steam, the amount of water covering the electrodes decreases, and current flow decreases. When current flow decreases to 10 percent below the current corresponding to the demand signal, the fill valve opens to increase the water level in the steam cylinder, which increases current flow and steam production. 5. Controller initiates drain/fill events to flush conductive ions As steam production continues, the concentration of conductive ions in the water increases, eventually leading to increased electrical current through the water. An algorithm monitors water conductivity and auto tunes drain and fill events to keep electrical current within demand parameters.

Verify that the humidifier is mounted level and securely supported before filling with water. See operating weights in Table 4-1. 5. Verify that the humidifier is level front to back and side to side after it is full of water. Safety functions XT humidifiers are protected against running dry — current does not flow if the electrodes in the steam cylinder are not submerged in water. If the current rating exceeds 120% of nominal current, the drain valve opens automatically. As the water level drops, the current rating drops back to the nominal value. If the current rating exceeds 120% of the nominal current after several drainage operations, the humidifier shuts down automatically. Capacity limitation XT humidifier capacity can be limited to a user-specified maximum: 6. Read the “Operation” section of the Vapor-logic4 Installation and Operation Manual. Note: During start-up, do not leave the humidifier unattended. 7. Perform all applicable “Start-up checklist” items. See Page 49. 8. Monitor humidifier operation through multiple fill cycles. The humidifier operating status appears on the keypad/display. 9. Perform the cleaning procedure as follows: a. Operate the humidifier long enough for steam to be produced. b. Drain the cylinder completely using the keypad/display: – At the Main menu, select Tank Status, and press Enter. – Select Mode Auto, and press Enter. – Select Drain, and press Enter. – Let the cylinder drain for 5 to 10 minutes until empty. c. Restart the humidifier, and repeat Steps a and b.
