13-17: Low-Speed Motor ExperienceMost of the cooling towers used all around the world are operating by using of standard fan unit solution such as fan impeller, gear box, driving shaft and motor. As presented in the previous paper, later fan unit development in the cooling tower industry can be slow running motor, which is directly coupled with fan impeller. This paper discusses slow running motor experiences of one of the European cooling tower manufacturer.

Inorganic phosphate is the most widely used mild steel corrosion inhibitor for open recirculating cooling water systems

while the CTI-ATC 105 (and also 140

The pulsation force is a combination of the aerodynamically generated pressure difference between the upstream and downstream side of the fan blade and the velocity (under) pressure generated by the surface of the blade tip

it only uses common sodium chloride salt as a feed stock

Cooling tower models were used to simulate industrial conditions and evaluate the efficacy of commercially available biocides against adherent (sessile) populations of microorganisms
