With rising energy costs, corporate sustainability has gone from pleasant theory to widespread practice. Changing light bulbs, implementing motion sensors and monitoring HVAC systems easily solve consumption issues for typical buildings, but solutions are not as simple for factory machines. For the packaging industry, there is a paradox: you must reduce energy use but keep your machines running.


Mitsubishi Electric provides hardware and software solutions that allow a single machine, a line or even an entire factory to be monitored and analyzed for energy usage. These tools provide the opportunity to assign an energy value to every product produced. With this information operations and engineering can take steps to reduce the worst offending processes one at a time and provide a real dollar value to calculate ROI on improvements made.

One of the easiest methods for realizing energy savings is to replace standard motor starters with VFD controlled motors. Already have VFDs? Check out Mitsubishi’s line of VFDs which use real time, optimized excitation control. These VFDs monitor the actual load needs and adjust the voltage and current needs in real time rather than using a predetermined load curve. This provides up to a 30% energy savings over most other VFD vendors.
