BAC driving fan system design


28 July 2020

The Baltimore Aircoil Company (BAC) says its ENDURADRIVE Fan System ensures peace of mind in mission-critical cooling applications through a simplified design.

The system features permanent magnet, direct-drive technology, in which the fan motor is directly coupled to the fan, eliminating the need for intermediary moving parts like gears or belts. The design is engineered so that the motor, VFD, and cooling tower work together to improve reliability.
The design is said to reduce the risk and cost of failures due to moisture ingress, with upgraded insulation, a double O-ring, a drive-end seal, and an integrated drain. BAC also offers an application-specific VFD with firmware designed and tested to optimise system reliability for any application. The system is engineered and CTI certified for extreme duty and to withstand thermal and vibration rigors of cooling tower operation.

BAC says that the ENDURADRIVE, which is suitable for process cooling, data centres, hospitals, laboratories and educational and government buildings, delivers the lowest total ownership cost of any cooling tower fan system on the market.

The direct-drive technology eliminates the need for inspection of fan belts and gears, while the streamlined design allows for easier overall inspection, maintenance, and service compared to other options on the market, thus reducing unplanned downtime.
