09-18: Recent Development in Motor Technology Allow Direct Drive of Low Speed Sidestream SofteningImproved reliability of cooling tower systems is now possible due to a new development in motor technology. This paper will discuss the development of low speed, permanent magnet motors and how they can be used in direct drive applications to eliminate the gearbox, NEMA motor, driveshaft, and disc couplings from cooling tower designs. A case study will be presented where an existing tower was refurbished using a direct drive motor which fit the exact

Both stress and vibrations are strictly related to the blade's dynamic response to the aerodynamic force's pulses

Understanding where to use bromine chemistry can produce an enhanced water management program

This paper also addresses issues relevant to the determination of the rate of the efflux from cooling towers of chemicals entrained in the drift

This paper reviews the chemistry of dispersion and the current methods and products for controlling deposition and presents data confirming the improved performance observed with recently developed polymer chemistry
