AN D S PECI FICATION S

M7-10

AV towers are galvanized steel, factory-assembled, general purpose crossflow cooling towers, designed to serve normal air conditioning and refrigeration systems as well as light industrial loads. They evolve from a singleflow concept of towers pioneered by Marley in the 1950s, and incorporate all of the design advancements that our customers have found valuable. They represent the current state of the art in this cooling tower category.

This booklet not only relates the language to use in describing an appropriate AV cooling tower—but also defines why certain items and features are important enough to specify with the intention of insisting upon compliance by all bidders. The left hand column of pages 18 thru 35 provides appropriate text for the various specification paragraphs, whereas the right hand column comments on the meaning of the subject matter and explains its value.

Pages 18 thru 25 indicate those paragraphs which will result in the purchase of a basic cooling tower—one that accomplishes the specified thermal performance, but which will lack many operation—and maintenance-enhancing accessories and features that are usually desired by those people who are responsible for the continued and continuing operation of the system of which the tower is part.

It will also incorporate those standard materials which testing and experience has proven to provide acceptable longevity in normal operating conditions.

Pages 26 thru 35 provide paragraphs intended to add those features, components, and materials that will customize the tower to meet the user's requirements.

Specifications Specification Value

AV Cooling Tower — Specifications: Base 22

7.0 Fill, Louvers, and Drift Eliminators:

7.1 Fill shall be film-type, thermoformed of

PVC, with louvers and eliminators formed as part of each fill sheet. Fill shall be suspended from hot-dip galvanized struc-tural tubing supported from the tower structure, and shall be elevated above the floor of the cold water basin to facilitate cleaning. The air inlet face of the tower shall be free of water splash-out.

7.2 Drift eliminators shall be PVC, triple-pass, and shall limit drift losses to no more than 0.005% of the design GPM flow rate.

Louvers integral with the fill keep the flowing water within the confines of the fill. The separate external louvers used by others permit water to escape the fill and form ice or produce an unsightly situation adjacent to the tower. If you plan to use your tower in the wintertime, particularly for free cooling, integral louvers will put your operating concerns to rest.

Drift rate varies with design water loading and air rate, as well as drift eliminator depth and number of directional changes. A drift rate of 0.001% is readily available on many stan-dard models. If a lower rate is required, please discuss with your Marley sales representa-tive.

The Marley X7™ fan is designed for induced-draft cooling tower and fluid cooler applications offering distinct advantages over other fan designs. The Marley FlareTip™ blade enhancement provides increased performance overcoming tip clearance losses—aiding the movement of air next to the fan cylinder.

The wide chord blade design is well suited for low noise operation as well, delivering superior air flow and pressure capability at reduced speed. The high performance X7 airfoil is one of the most efficient in the industry today.

The hollow 6063-T6 aluminum alloy extruded blade is designed with a deep section airfoil making the X7 robust, yet light and easy to handle. It also withstands the extreme heat and humidity imposed by the rigorous cooling tower environment.

The blade end-caps are injection molded impact-resistant, polypropylene with a section on the upper surface to allow for consistent fan pitch setting.

Additionally, all X7 fan assemblies are statically balanced at the factory to minimize vibration.

Each blade is secured to the hub with two stainless steel U-bolts that allow blades to be easily rotated to adjust desired pitch angle, delivering precise utilization of fan horsepower.

Superior strength, excellent quality, light weight and outstanding performance makes the X7 fan an outstanding choice for cooling tower applications—and best of all it’s made by Marley.

High Efficiency The aerodynamic design optimizes the performance characteristics of the X7 blade.

The FlareTip design, adapted from the well-proven and highly successful Marley HP7i and HP7000 fiberglass fans, is a characteristic unique among extruded aluminum fan designs.

The blade taper and flared tip reduce blade tip losses and distributes airflow evenly across the entire blade length, improving overall fan efficiency.

Lightweight The single-piece X7 hub design was chosen specifically to work in an evaporative cooling environment at the common fan diameter range of factory-assembled package products.

This optimization allowed for a significantly smaller overall hub compared to other manufacturer’s offerings, yielding significant weight savings. Additionally, the simple and proven U-bolt method of blade to hub connection results in a minimum quantity of hardware.

Corrosion Resistance Marley X7 fans are designed for continuous duty in all cooling operating environments. Available in diameters from 66" through 168", the X7 utilizes a single-piece galvanized ductile iron hub with series 300 U-bolts. Blade shanks are galvanized carbon steel, and all blade hardware is series 300 stainless steel. 316 stainless hardware and triple-epoxy hub coating is available as an option for more corrosive environments.

Fan Assembly Instructions

The following instructions apply to installations having straight bores or tapered output shafts without split taper bushings.

It is convenient to preassemble the fan prior to installation on the driving shaft.

Marley X7 fans are statically balanced as a complete assembly. If fan is shipped unassembled, blades and hubs are match-marked to insure proper re-assembly.

1—Select a large open area corresponding to the fan diameter.

2—Position the fan hub 1 in the center of the work area with the blade sockets up.

3—Place a blade 2 in a blade socket on the hub. On fans where the blades overlap at the hub be sure to have the leading edge under the trailing edge of the forward blade. Refer to Figure 2.

4—Ensure the blade shank safety collar is inboard of the inner hub rim.

Refer to Figure 3.

5—Lubricate U-bolt threads and bearing surface of self-locking nuts.

Install U-bolt through inner row of holes in the hub. Finger tighten the self-locking nut with flat washer onto U-bolt threads. Progressively tighten each leg of the U-bolt until blade is held in place.

6—Pull blade radially outward to be certain the shank safety collar is in contact with hub inner ring. Refer to Figure 3.

7—Repeat steps 5 and 6 as required with the outer U-bolt 4.

8—Repeat steps 3 through 7 for all blades.

Fan Installation Instructions

1—Be sure motor is locked out.

2—Clean the hub bore and driving shaft extension for the full length of the key.

3—Insert the key in the keyway. The top of the key must be below the top of the shaft by not more than 1/8″ (3 mm) . The key is a tight fit across the width and must never be altered.

4—After cleaning, apply a coat of anti-seize compound to the engage-ment portion of the shaft.

5—Raise the fan assembly above the shaft and slowly lower the hub onto the shaft with the keyways aligned. Make certain the key does not slide down during installation.

6—Install the Hub Retention Cap Screw with Lock Washer. Torque hub retention cap screw to 40 ft·lbƒ (54 N·m).

Adjusting Fan Blade Pitch

The trial pitch is the calculated setting for design conditions (water rate , heat load, air density, and brake horsepower). The trial pitch is provided by SPX (see page 2).

1–Select a position on the fan circumference and rotate each blade to this common location when setting or checking blade pitch. Support the blade tip to maintain a common rotation plane while setting the fan pitch. The pitch is set by placing a protractor on top of a straight edge or with a digital level that extends across blade near the tip. For flare-tip blades, the pitch is measured across the end cap as shown in Figure 4.

For full chord blades, the pitch is measured across the aluminum airfoil about 1” inboard of the end cap as shown in Figure 5.

2–Be sure all blades are positioned correctly on hub, then set the pitch.

Blades should be within ± 1/4° of the desired pitch angle. After the de-sired setting is obtained, progressively tighten the U-bolt nuts according to Table 6. Recheck the pitch angle. If required, loosen the hex nuts and reset the pitch as necessary until the proper pitch angle is obtained.

Fan Maintenance

Preventative maintenance will prolong useful life and assure continued trouble-free operation. After the first week and subsequently at six month intervals:

cylinder segments, and corrosive attack. Correct any situations deter-mined detrimental to fan operation.

Service

Proper identification of your fan is necessary to insure you receive cor-rect replacement parts. The Marley cooling tower serial number can be used to determine the fan and any components installed and maintained as original equipment on a Marley cooling tower. Please provide the Marley sales representative the necessary information when ordering replacement fans or components.

Replacement of individual fan blades may require rebalancing the entire fan.

If rebalancing is desired, contact the Marley sales representative in your area.

Motor Load

The corrected horsepower should be close to but not exceed the con-tract horsepower specified by SPX. Determine corrected horsepower using the following equation.

Actual volts and amperage must be obtained with the fan running and the specified rate of water flowing over the tower after the motor and Geareducer have reached operating temperature (approximately 30 minutes of operation).

Note Measurements taken on motors operating with Variable Fre-quency Drive controls may read up to 15% high from errors in measuring the approximated sine wave. Instruments capable of measuring a squared off wave form accurately should be used for measuring power in this situation.

Do not start the motor more than four to five times per hour (each low speed start and each high speed start count as one start).
