69-07: Application of AC Motors to Cooling Towers Specifications of Cooling Tower Water TreatmentsThe application of AC squirrel cage motors to cooling towers requires special consideration to problems of high humidity, loads that vary with ambient temperature, installations at many different altitudes and power supplies with many different voltages. Torque and inertia acceleration capability are also of major concern. With the motor industry presently completing its transition to NEMA T frames, the timing is right to review the capability of

amoeba-resisting microorganisms such as Legionella

Effective control is accomplished at very low or sub detectable levels of free available halogen

heat transfer coefficients

In order to eliminate the many problems associated with this technology

bromide-activated planktonic bacteria

the overhead condenser and a dollar cost which could easily pay for

This paper will point out the unique features of this family of products and show comparative field and laboratory data to aid in proper biocide selection

mechanical draft

Case studies of field trials will be discussed as well as benefits and details of the new feed system

and immunity to rot and decay
