Since EC motors are 90% more efficient there is a short pay-back period due to the significant energy savings and cost savings over the lifetime of the product. In addition, the electronics in the motor allow for speed control, sensor control, and MODBUS integration. This can link directly up to the BMS (Building Management System) of a facility. The fan can operate in constant flow, temperature control, or pressure control applications. Alarm relays and tach-out signals can also be monitored to ensure proper operation.
