330 Service and Maintenance of Cooling Towers
Phil Rodin, United Association
The objective of this course is to provide the instructor with the information necessary to teach students the
principles of Cooling Tower Service and Maintenance. Course topics will include: Safety, Tower Configuration,
Water Quality, Inspection Procedures, Repair Procedures, and Tower Retrofit Guidelines. The objective of a
mechanical refrigeration system is to remove heat from a space or product and to reflect that heat to the en-
vironment in some acceptable manner. Cooling towers are frequently used to reflect heat from mechanical
refrigeration and air-conditioning systems in many commercial buildings, hospitals, and universities. Cooling
towers, because of their mode of operation, can create ideal conditions for microbial growth.
