Unpacking High-Efﬁ ciency Tubes

UNPACKING HIGH-EFFICIENCY TUBES

NOTE: If you have an Ultra-sorb without High-efﬁ ciency dispersion tubes (noninsulated tubes), please skip to the next page.

UNPACKING

• Remove the dispersion assembly from the shipping container; be careful not to damage the PVDF insulating material on the dispersion tubes.

• Some dispersion panels are shipped unassembled. Do not lay HighEfﬁ ciency Tubes across or under anything that could compress or damage the insulating material. Compressed insulating material has a reduced R-value.

• Before start-up, remove the clear poly ﬁ lm covering the insulation by tearing it along the perforation. Do not use a knife or sharp object to remove the

poly ﬁ lm.

CAUTION

Remove clear poly ﬁ lm; do not remove white PVDF insulation.

High-efﬁ ciency tubes are sleeved in clear poly ﬁ lm for protection during, shipping, and installation. Leave the clear poly ﬁ lm on until installation is complete.

Remove and discard the clear poly ﬁ lm before start-up by tearing it along the perforations. Do not remove the white

PVDF insulation.

• Keep ﬂ ame away from the insulation to avoid damage.

• PVDF is resistant to UV light. UV-C light from germicidal lamps will not cause the insulating material to degrade.

• Do not tighten mounting clamps or fasteners to any part of the dispersion tube.

High-efficiency tube option

Dispersion assemblies with the High-Efﬁ ciency Tube option are designed to produce signiﬁ cantly less dispersion-generated condensate and airstream heat gain, which reduces wasted energy by up to 85%.

Ultra-sorb Model MP ﬁ eld assembly

INSERT DISPERSION TUBES INTO AN UNASSEMBLED ULTRA-SORB PANEL

If the Ultra-sorb Model MP panel was shipped unassembled, the dispersion tubes need to be inserted into the panel.

Note: Use soapy water to lubricate end of tubes where inserted into rubber grommet.

1. Insert tube into rubber grommet at panel header, with open end at bottom. Insert at a slight angle to not interfere with top frame of Ultra-sorb panel.

2. Press downward on tube so to clear stud at top of tube. Align tube with rivet nut on top of the header.

3. Once aligned, turn the tube three full rotations into rivet nut for proper engagement.

4. Turn the tube backwards so that the steam tubelets face the next tube, perpendicular to air flow. Face the lowest tubelet of each tube in the same direction so the facing tubelets are at staggered heights.

INSTALLATION

5. Tighten the locknut down to the top header to 10 in-lbs (1.13 N-m). Note: If the rivet nut pulls through, add a ¼"-20 nut on each side of the top flange to secure the tube.

INSTALLATION

Selecting the location

DETERMINE HUMIDIFIER PLACEMENT

Dispersed steam must be absorbed into the airﬂ ow before it comes in contact with duct elbows, fans, vanes, ﬁ lters, or any object that can cause condensation and dripping.

• Install the Ultra-sorb panel in a location where discharged water vapor will be absorbed by the airstream.

• Place the Ultra-sorb panel where the air temperature is capable of absorbing discharged steam without causing condensation at or after the unit. This will normally be downstream from the heating coil where the air is warmest.

• Do not place the Ultra-sorb panel in an outside air intake unless the air is tempered with a preheat coil.

• Do not place the Ultra-sorb panel near the entrance of a high-efﬁ ciency ﬁ lter. The ﬁ lter will remove visible moisture and become waterlogged. See the Caution "Installing the Ultra-sorb panel upstream from ﬁ lter media" on page 21.

• Do not place the Ultra-sorb panel where discharged visible mist will impinge directly on a metal surface.

mc_071111_1710

PLACEMENT IN AN AIR HANDLING UNIT

• Location A is the best choice. Installing downstream from heating and cooling coils provides laminar ﬂ ow through the dispersion unit; plus, the heated air provides an environment for best absorption.

• Location B is the second-best choice. However, conditions when both cooling and humidiﬁ cation is needed, the cooling coil will eliminate some moisture for humidiﬁ cation.

• Location C is the third-best choice. Air leaving a fan is usually very turbulent and can cause vapor to not absorb at the expected non-wetting distance. Allow for more distance if installing downstream from a fan.

• Location D is the poorest choice. The cooler air at this location requires an increased non-wetting distance.

INSTALLATION

Mounting and support

INSTALLATION IN A COLD AIR STREAM

When a humidiﬁ er is installed in a duct that will carry cold air, determine the dew point temperature. If the psychrometric chart reveals that saturation may occur, protection should be provided. A high-limit humidistat or humidity transmitter can be used for this purpose. See Figure 8-1.

PLACEMENT UPSTREAM FROM AN ELBOW OR DUCT SPLIT

Installation upstream from elbows or duct splits can be done. See Figure 8-2 if placed upstream a minimum of the non-wetting distance.

INSTALLATION ABOVE VALUABLE EQUIPMENT

Water piping and humidiﬁ ers should not be installed above expensive equipment. A condensing or leaking water pipe or other accidental water spillage could damage the equipment below. When such an installation cannot be avoided, install a drip pan under the humidiﬁ er piping, valve, etc. to catch and drain away unintended water. See Figure 8-3.

PANEL SUPPORT

The duct or air handler section and Ultra-sorb panel must be properly supported to carry the weight of the assembly. The weight of the piping must be supported by the building structure rather than by the Ultra-sorb unit. Excessive weight on the Ultra-sorb panel may stress the connections, causing them to fracture and leak.

Mounting and support

INSTALLATION

The Ultra-sorb panel can operate with air ﬂ ow in either direction. The steam supply and condensate drain connections must be connected to the header assembly. To locate connections, the panel may be rotated 180º to the preferred side of the AHU or duct.

Once installed, verify that all steam discharge tubelets are pointed perpendicular to the airstream (see Figure 9-1). Loosen the jam nut at the top of the tube to allow rotation of the dispersion tubes for proper tubelet orientation.

When removing and installing the dispersion tubes, verify that the replacement grommets are seated in their grooves and lubricated. When sliding the dispersion tube into the grommet, be careful not to cut the grommet.

Note: To prevent leakage, use HVAC caulking or a similar weather sealant to

seal all places where the Ultra-sorb installation hardware and ﬁ ttings penetrate the wall of the duct.

Mounting and support

MOUNTING IN AN AIR HANDLING UNIT

See placement recommendations in Figure 7-1.

The metal support frame should be anchored to the air handler casing. Recommended fasteners for mounting the Ultra-sorb to a metal support frame are 1/4–20 nuts and bolts or #12 self drilling and tapping screws. Due to the possible forces exerted on this application, DriSteem recommends fastener spacing not to exceed 6" (150 mm). On larger Ultra-sorb installations, vertical channels may be required on both the inlet and outlet ends of the humidiﬁ er to provide proper support. See Figure 12-2.

STEAM FROM A PRESSURIZED STEAM

Ultra-sorb panels for pressurized steam have a threaded pipe nipple that extends outside the framework for a steam supply connection. The steam supply line should be dripped immediately ahead of the steam valve through a steam trap. See Figure 14-3.

RECOMMENDED TRAP FOR STEAM MAIN DRIP LEG

Use a ﬂ oat and thermostatic (F&T) trap on the steam supply ≤15 psi and inverted bucket if > 15 psi.

DRIEST STEAM

To ensure driest steam, take humidiﬁ er steam off the top of the steam main (not the side or bottom).

STEAM FROM A NON-ELECTRODE-TYPE EVAPORATIVE HUMIDIFIER

This section provides piping instructions for resistive-element electric, gasto-steam, and steam-to-steam evaporative humidiﬁ ers. For electrode-type (DriSteem XT Series) humidiﬁ er piping, see Page 19.

TUBING

Standard connections on DriSteem evaporative humidiﬁ ers are 1½" (38 mm) stainless steel tubing. Two inch tubing connections are available as an option on higher capacity evaporative units. Hose cuffs are available for connecting to the tubing connection on the evaporative humidiﬁ er and to the Ultra-sorb (see Figure 18-2). DriSteem can also provide threaded connections on the evaporative humidiﬁ er and on the Ultra-sorb. For threading pipe connection options, see DriSteem’s DriCalc sizing and selection software, available at www. dristeem.com.

When non-threaded pipe is used, steam hose and clamps can be used for connections at the humidiﬁ er steam outlet and at the Ultra-sorb. Due to the difference between the tubing O.D. and the steam hose I.D., multiple hose clamps may be required.

• 90° elbows are not recommended. Use two 45° elbows one foot apart (see Figure 18-2).

Failure to follow the above recommendations may result in excessive back pressure on the evaporative humidiﬁ er. This may lead to loss of water seal or leaking gaskets. When the distance between the Ultra-sorb and the evaporative humidiﬁ er exceeds 20 feet (6 m), consult the factory for special recommendations.

• Thin wall tubing will heat up with less start up heat loss than heavy wall pipe.

• Insulate the tubing to reduce the loss in output caused by condensation in the tubing.

STEAM FROM AN ELECTRODE-TYPE EVAPORATIVE HUMIDIFIER

TUBING

Standard steam hose connects to DriSteem electrode steam humidiﬁ er cylinders (XT series) and to the Ultra-sorb steam inlet directly or with a stainless steel adaptor. Hose cuffs are also available for connecting tubing. If speciﬁ ed when ordered, DriSteem can provide a threaded connection on the Ultra-sorb steam inlet. For threading pipe connection options, see DriSteem’s DriCalc sizing and selection software, available at www.dristeem.com.

Hose and clamps can be used for connections at the steam cylinder and at the Ultra-sorb. Due to the difference between the tubing O.D. and the steam hose I.D., multiple hose clamps may be required.

STEAM HOSE PITCH

Support steam hose to prevent sags or low spots, and pitch at least 2"/ft (15%) toward the Ultra-sorb panel.

TUBING PITCH

• Pitch at least 1/8" /ft (1%) toward the Ultra-sorb.

• 90° elbows are not recommended. Use two 45° elbows one foot apart as shown in Figure 19-2.

Condensate drainage for all applications

Since Ultra-sorb panels operate with virtually zero internal pressure, condensate cannot be piped directly into a return main. It must be piped to a ﬂ oor drain or into a condensate pump and returned to the steam source.

To prevent steam from escaping down the drain line, install a water seal or steam trap in the drain line. The water seal must be of sufﬁ cient height to contain the pressure in the humidiﬁ er.

FIGURE 19-1: CONDENSATE DRAINAGE

Failure to follow the above recommendations may result in faults at the electrode-type humidiﬁ er. This may lead to erratic or stopped operation. When the distance between the Ultra-sorb and the evaporative humidiﬁ er exceeds 20 feet (6 m), consult the factory for special recommendations.

• Thin wall tubing will heat up with less start up heat loss than heavy wall pipe.

• Insulate the tubing to reduce the loss in output caused by condensation in the tubing.

OPERATION

Replacing Ultra-sorb Model MP dispersion tubes

REMOVING A DISPERSION TUBE FROM AN ULTRA-SORB PANEL

A dispersion tube may need to be removed for access to an adjacent coil, or because of tube damage or upgrade to an insulated tube. See page 3 for how to install a dispersion tube.

1. Apply soapy water around the tube grommet to ease turning and removal of the dispersion tube.

2. Loosen the jam nut from the tube nut at top of the tube. Rotate the tube off the top frame assembly bolt (about 4 rotations of the tube).

3. Press downward on the tube so to clear bolt at top of frame.

4. Move the tube to a slight angle so that it does not interfere with top frame of Ultra-sorb Model MP panel.

5. Pull the tube out from the rubber grommet.

6. If the grommet shows any sign of wear or damage, replace it before reinstalling the dispersion tube. See Table 29-1 for replacement parts. Note: Grommets are provided with replacement tubes.

Performance data

OPERATION

NON-WETTING DISTANCE

Non-wetting distance is the distance downstream from the leaving side of the steam dispersion assembly to the point where wetting will not occur. This distance is dependent on several application parameters. To determine your dispersion assembly’s non-wetting distance, consult your system’s design engineer or project documentation. Non-wetting distance can also be calculated using DriSteem’s DriCalc sizing and selection application, available at www. dristeem.com. Note that your current design conditions may vary from conditions used for system design.

• Note that the rise in relative humidity (ΔRH) between entering and leaving air has a direct bearing on the non-wetting distance. As the change in relative humidity (ΔRH) increases, the non-wetting distance increases.

• Uneven airﬂ ow over the Ultra-sorb panel cross-section may result in nonuniform mixing of steam with air, which may adversely affect absorption distance.

Table 21-1: Ultra-sorb air pressure loss

Duct air velocity

(55 ˚F at sea level)

• A small amount of duct air pressure loss will be present downstream from the Ultra-sorb panel, depending on air density, velocity, and tube spacing. See Table 21-1.

Startup

1. Turn on humidification steam to the Ultra-sorb supply header:

• Pressurized steam: Open the modulating steam valve.

• Evaporative humidiﬁ er: Follow the startup instructions in the humidiﬁ er's Installation, Operation, and Maintenance Manual.

2. Check for piping leaks.

3. See “Steam traps” on page 24.

4. Check the dispersion tubes for leaks.

5. Ensure that the dispersion tubes are oriented with the tubelets at a right angle to the airflow. See Figure 9-1.

6. Check for any other leaks from steam and drain connections.

7. Ensure that the P-traps are operating.

• At the beginning of the season, ensure there is a stream of water from

condensate drain when operating.

1. If not, verify P-trap is not blocked.

2. If steam is blowing out of the P-trap, it needs to be primed.

3. Verify the P-trap is tall enough to contain panel operating pressure (see page 10 or 11).

4. Duct static pressure > 2.5" ( 63.5 mm) wc may require a taller P-trap.

MAINTENANCE

Inspecting and servicing components

STRAINER

Inspect the strainer screen at least twice during the ﬁ rst year. If fouled, inspect it more frequently.

STEAM TRAPS ON MAIN STEAM SUPPLY

At least twice a year verify that steam traps are functioning properly. A blocked steam trap is cold. A "blowing" steam trap is hot and noisy, and the discharge pipe from it is hot for 30 feet. A properly operating steam trap is hot and makes noise at intervals, and the discharge pipe is progressively cooler beginning at the trap.

VALVES

• Electric modulating:

Inspect annually to be sure that the valve operates freely and closes off

steam tightly and the stem packing is not leaking.

• Pneumatic:

Inspect annually to be sure the valve closes off steam tightly, the stem

packing is not leaking steam, and the diaphragm in the actuator is not leaking air.

HIGH-EFFICIENCY TUBES

• If the insulating material gets dirty or smudged, gently clean it with a damp cloth and a solution of soapy water or diluted non-toxic, biodegradable cleaner/degreaser.

• Do not clean the insulating material with a pressure washer. The direct spray could cause damage.

• If using a torch in the vicinity of the dispersion panel, keep the ﬂ ame away from the insulating material to avoid damage.

• PVDF is inherently resistant to UV light. Indirect, low-intensity UV-C light from germicidal lamps will not cause the insulating material to degrade.

• Do not tighten mounting clamps or fasteners to any part of the dispersion tube.
