In response to the demand to operate as efficiently as possible, freezing systems have stepped up to aid in energy management. Most of the improvements that have been made to modern freezing systems are in the areas of control and automation, says Eldon Roth, founder and chairman of Beef Products Inc.
"Today, it is possible to continuously monitor and record all operating parameters of the system so that historical comparisons can be made to identify opportunities for greater efficiency," he explains. "Related to this is the automation of motors using variable-frequency drives (VFDs). The use of VFDs on all motors allows for the adjustment of motor speed to maintain optimal operating conditions."
