Specifications

Fan Motor Starter Control Panel:

6.4Add the following paragraph in the Mechanical Equipment sec- tion: Each cell of the cooling tower shall be equipped with a UL listed control system in a IP14 or IP56 out- door enclosure capable of controlling single-speed or two-speed motors as required, and designed specifically for cooling tower applications. The panel shall include a main fused disconnect or main circuit breaker with an external operating handle, lockable in the off position for safety. Across-the-line mag- netic starters or solid-statesoft-start starters as required shall be controlled with a thermostatic or solid-state temperature controller. Door mounted selector switches shall be provided to enable automatic or manual control and wired for 240VAC control. Control circuit to be wired out to terminal blocks for field connection to a remote vibration switch, overload trip alarms and remote temperature control devic- es. The temperature controller shall be adjustable for the required cold-water temperature. If a thermostatic control- ler is used it shall be mounted on the side of the tower with the temperature sensing bulb installed in the cold water basin using a suspension mounting bracket. If a solid-state temperature controller is used the controller will be door mounted on the control panel. The temperature controller will display two temperatures, one for outgoing water and the other for set point. Water temperature input shall be obtained using a three-wire RTD with dry well in the outlet water piping and wired back to the solid-state tempera- ture controller in the control panel.

■If it is your opinion that the control system for the cooling tower be part of the tower manufacturer’s responsibility, we are in wholehearted agreement with you. Who better to determine the most efficient mode and manner of a cooling tower’s operation— and to apply a system most compatible with it—than the design- er and manufacturer of the cooling tower?

Marley variable speed drives are also available for the ultimate in temperature control, energy management and mechanical equip- ment longevity. See specifications on page 16.
