The ENDURADRIVE®  Fan 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 advanced design is specifically engineered so that the motor, variable-frequency drive (VFD), and cooling tower work together to provide unparalleled reliability. The design reduces 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. What’s more, the company offers an application-specific VFD with firmware designed and tested to optimize system reliability for any application. ENDURADRIVE is engineered and certified by the Cooling Technology Institute (CTI) for extreme duty and to withstand thermal and vibration rigors of cooling tower operation. The fan system is suitable for all mission critical cooling applications, including process cooling, data centers, hospitals, laboratories, and even educational and government buildings.
