1250 CFM, 2 HP, TWO CARTRIDGE AUTO PULSE DUST COLLECTOR

1. Soft motor starting: The amperage draw will not exceed the motor name plate rated amperes at any time. This reduces the initial cost of copper wiring because it is no longer necessary to consider the initial startup load. The initial startup requirements may exceed 5 times the rated name plate amperes when hard starting a variable torque application like high speed impellers. This requires oversizing of electrical wiring, fuses and breakers to prevent motor starvation and premature failure of electrical components on startup.
2. On-Off Switch: Conveniently located on the dust collector, this is a simple 24 volt relay loop that engages the variable frequency drive with the push of a button. After the start comand is triggered the motor will ramp to maximum velocity over ~ 20 seconds. When the stop command is received the unit will again decelerate over ~ 90 seconds and come to a complete stop.
3. Thermal Motor Protection: The motor drive will constantly monitor the motor and the drive itself for any unusual spike in temperature throughout. If the temperature rises above acceptable perameters the drive will default and shutdown before any damage to the unit is sustained.
4. Motor Fault and Report Monitoring: The motor drive is capable of displaying motor torque, hours of operation, actual amperage draw, percentage of motor capacity used, percentage of drive capacity used, the motor frequency in hertz, delivered line voltage and several other programable LED display readouts. Factory settings are always in hertz frequency unless specified otherwise.
5. Automatic Load Compensation Controls: The motor drive is programed to compensate for changing load conditions. These conditions include but are not limited to extended length or reduced diameter of piping, blast gates and other restrictions in the air lines, atmospheric humidity, temperature and altitude adjustments, filter cartridge dust cake levels, and power supply brownout or overcurrent conditions.  With our VFD electrical package these conditions are corrected automatically through direct motor communication with the drive system. As a result, if the cfm should fall below rated levels, the motor drive will increase the motor speed to correct for this condition. The speed of the motor will continue to increase until 150% of the rated water column vacuum is achieved to restore air flow and maintain 100% load on the motor. The LED display will show this reading in real time with .1 hertz accuracy. This reading can also be used as a baseline to determine the most effective time to pulse the filters.  We highly recommend the use of this system when possible. This can only be used when unit is placed inside as the contoller has a Nema 1 electrical rating.
