Fan?Drive System
? ?BALTIDRIVE? Power Train System
The fan drive system provides the cooling air necessary to reject unwanted heat from the system to the atmosphere. The standard fan drive system on the Series 1500 is the BALTIDRIVE? Power Train. This BAC engineered drive system consists of a specially designed powerband and cast aluminum sheaves located on minimum shaft centerline distances to maximize belt life. A premium efficient cooling tower duty fan motor provides maximum performance for cooling tower service.

? ?Independent Fan Operation
Models 15296 through 15425 are provided with one fan motor driving two fans as standard. The independent fan option consists of one fan motor and drive assembly for each fan to allow independent operation, adding an additional step of fan cycling and capacity control.
? ?BALTIGUARD? Fan System
The BALTIGUARD? Fan System consists of two standard single-speed fan motor and drive assemblies. One drive assembly is sized for full speed and load, and the other is sized approximately 2/3 speed and consumes only 1/3 the design horsepower. This configuration allows the reserve capacity of a standby motor in the event of failure. As a minimum, approximately 70% capacity will be available from the low horsepower motor, even on a design wet-bulb day. Controls and wiring are the same as those required for a two-speed, two-winding motor. On some units the standby fan motor can be increased to the size of the main motor for 100% redundancy.
