Las Vegas-based motor efficiency controller maker Power Efficiency Corp. (Booth W118022) is using NPE2009 to introduce itself to the North American plastics industry a market that company officials said is rife with opportunities to sell its energy-saving devices.
Power Efficiency's patented E-Save technology uses a microprocessor and circuitry to monitor the energy requirements of a motor.
By monitoring both voltage and current being fed to the motor, it can precisely calculate the power the motor requires, a company flier said. The high-speed response circuits continuously monitor the current and voltage to instantly provide the exact amount of energy the motor needs. This reduced unnecessary energy use. As a result, the motor maintains its rated speed and torque under variable loads, while reducing the energy consumption of the motor.
The inrush of electricity to a machine on startup can actually cause a power shutdown in industrial facilities, said Jay Mistry, the company's director of business development, in a June 24 interview at NPE.
Power Efficiency's E-Save creates a soft start and reduces energy consumption throughout its run. The units are best suited for variably or lightly loaded applications, Mistry said, citing the vertical transportation industry elevators and escalators as examples of commonly used applications for Power Efficiency's technology. It is designed for motors that are running constantly but need an influx of electricity in variable doses.
A common example in its early adoption in the plastics industry has been for granulator units, Mistry said. The grinders run constantly and require a jolt of power only when scrap materials are added. During low load times, the unit conserves energy by shutting off the voltage for part of the half cycle.
Power Efficiency technology is being used in plants owned by packaging firms Berry Plastics Corp., Graham Packaging Co. LP and Ball Corp.
Company officials are in the midst of testing their products on injection molding, injection blow molding and extrusion machines.
