BRAHM TM BC Central Collector Series
Soft Start The use of a Variable Frequency Drive (VFD) allows the motor ramp up to speed rather than across the line starting contactors. This eliminates starting amperage spikes as well as inertial effects of the blower. In non-VFD systems, these spikes can be as high as eight times the full load amps. Pressure Tracking The Variable Frequency Drive (VFD) inside the control panel allows the unit to track the usage of the filters. This allows the unit to automatically increase the speed of the motor to compensate for the additional air restrictions caused from dirty filters. This feature is an automatic feature and cannot be disabled. This feature alone can save up to 50% of the energy costs over the life of the filters. Reduced Maintenance The Variable Frequency Drive (VFD) manages the motor's operating speed. This in turn controls the airflow inside the unit and allows for more efficient operation through the Pressure Tracking feature. This reduces the impaction of dust upon the filters inside the unit and allows. The reduced impaction means the dust can be cleaned easier and every cleaning cycle is more efficient. This feature can increase the life of the filter by up to 100% which reduces maintenance time and costs. Reduced Noise Noise is created inside a unit by moving parts such as the blower wheel and moving fluids such as the air through the unit. With the VFD, the air flow is managed through the blower control. By managing the airflow, the noise due to moving parts and moving air is reduced.
