4.0Fan Deck and Fan Cylinder:

4.1The fan deck shall act as a working platform for maintenance personnel. It shall be fabricated of no less than 12 gauge steel, and shall be designed for a uniform live load of 60 psf.

4.2Fan cylinders shall be molded FRP.

They shall be through-bolted to the fan deck structure to provide a consistent- ly stable operating shroud for the fan.

5.0Mechanical Equipment:

5.1Fan(s) shall be propeller-type, incorpo- rating heavy duty blades of cast alumi- num or high strength, inert composite material. Blades shall be individually adjustable and replaceable. Fan(s) shall be driven through a rightangle, indus- trial-duty, oil-lubricated, geared speed reducer. Speed reducers employing pulleys and belts will not be accepted.

5.2Motor(s) shall be ____ hp maximum,

TEFC, 1.15 service factor, and specially insulated for cooling tower duty. Speed and electrical characteristics shall be 1800 (1800/900) RPM, single winding,

___ phase, ___ hertz, ___ volts.

The indicated design values for framing and decking not only give you assurance that the tower can withstand long term operation in a hostile environment — but that it will accept many years of inspection and maintenance traffic by your operating personnel.

Fiberglass-reinforced polyester fan cylinders provide the close tip clear- ances and smooth airflow contour necessary for good fan performance. The inert, noncorroding nature of FRP assures that these characteristics will persist. Their 6' to 7' height also provides protection for operating personnel.

Propeller-type fans require only half the operating HP of blower-type fans.

They should be readily adjustable to permit compensation for job site conditions that may tend to overload the motor. The fans of one manu- facturer require the purchase of special positioners for each increment of fan blade pitch.

Standard fan drives of other manufacturers may use V-belts. Considering the size of fans involved — and the horsepower applied — this is not good design practice. Geareducer® drive is far more reliable and trouble free, and is currently offered as an option by at least two other cooling tower manufacturers.

Unless otherwise specified, motor speed will be 1800 RPM in 60 Hertz areas and 1500 RPM in 50 Hertz areas. If you prefer the operating flex- ibility of two-speed operation, please specify the RPM to be 1800/900 (1500/750 in 50 Hertz regions).
