PLUG & SAVE
ENERGY SAVING IN HOMOGENIZER AT FOOD INDUSTRY PLANT
CLIENT PROFILE
Poliva manufactures and markets raw materials for the bakery industry. The products list includes: margarines, fats, fillings, spreads, baking improvers and other materials. Poliva has various SinuMEC installations on Ammonia compressors, chocolate mixers and homogenizers.
BUSINESS NEED
The ever increasing electricity prices and business demands for increased profitability led Poliva to explore a solution that would provide more functionality than just motor starting. Due to the high starting currents during motor starting and local regulation an advanced energy efficient solution was required.
Poliva chose PowerSines innovative Sinusoidal Motor Efficiency Controller (SinuMEC) due to its industry leading starting solution. The benefits of choosing PowerSines innovative Sinusoidal Motor Efficiency Controller (SinuMEC) included reduced voltage motor starting, high energy savings and improved power quality.
SOLUTION
The homogenizer is used to mix different fluids. Prior to installation, estimations showed that the motor was fully loaded during its entire period of operation. In actuality, the homogenizer was not loaded during 30% of its operating time. During this period SinuMEC was in "Save Mode" and improved motor efficiency.
The SinuMEC system provides harmonics-free motor starting as well as energy savings. SinuMEC controls the voltage supplied to the motor, allowing reduced voltage startup, and while the motor runs it adjusts the voltage according to the load. Due to the structure of electric motors, reducing the supplied voltage while partially loading the motor, increases its efficiency and lowers its internal losses. SinuMEC does not generate harmonics and is EMI/RFI free.
SinuMEC is built around the patented RIGHTVoltage technology, which controls and stabilizes voltage supplied to the AC motor utilizing proprietary methods for combining three-phase voltage vectors (VVC - Voltage Vector Combination), all the while maintaining a pure sinusoidal waveform.
While the motor's control voltage was kept unchanged, the power voltages supplied through SinuMEC were constantly measured for power demand and modified accordingly. Following the success of this installation, SinuMEC became the standard for energy savings devices in the factory.
RESULT

 |
 |
|
Smooth motor starting with reduced voltage. The Startup current was only 1.1 times the motor nominal current.
|
SinuMEC saved 02.8% in line losses and 36.6% in active power.
|
SinuMEC does not generate any side effects and does not require any filters. It improved Poliva’s power quality by filtering harmonics and improving the power factor.
