determined Polyflor’s site had a 269,827kWh annual load which would benefit significantly from voltage optimisation. They guaranteed the installation of the Powerstar system would provide energy consumption savings of 9%. To verify these guaranteed savings Polyflor requested on/off testing at the site to compare data both with and
machinery operates more efficiently, and reducing the business’s carbon footprint. EMSc found that a correctly valuated and implemented VO unit would reduce electricity consumption by a minimum of 6%, ensure machinery was operating more efficiently while maintaining existing output and, as less energy would be consumed, the company would be promoting its commitment to the

without the Powerstar. Both periods were run over duplicate days to ensure like for like comparisons could be made. The results from the tests indicated the potential for annual energy consumption savings of 34,619kWh, equating to a12.8% reduction and annual financial savings of £3,635. Another business, PALRAM Polycarb, was a significant consumer of electricity through the manufacturing process of thermoplastic sheets at the company’s main production plant in Doncaster. They turned to EMSc with very specific goals that they wanted to achieve from a voltage optimisation system which included: reducing electricity consumption and its associated costs, ensuring existing
environment; meaning all three of PALRAM’s targets would be achieved. With that in mind, a tailor-made voltage optimisation solution was designed and installed and in the first six months a Powerstar 1500kva unit achieved energy savings in excess of 180,000kWh. This enabled the company to reduce its energy consumption by over 6% and save some £18,000 in electricity costs. With machinery running at the optimum voltage and with harmonic distortions smoothed, maintenance costs were also lowered. Furthermore, the real time monitoring system which is a standard feature of all Powerstar units, is enabling PALRAM to take further steps to reduce overall
electricity consumption; independently. Matthew Healey,
PALRAM Polycarb’s technical manager, spoke of his surprise at actually being able to increase manufacturing output despite using less power: “With continual monitoring we expect to see savings in excess of the 6% guarantee – a great level of return on investment. We are now able to produce up to 50 tons more product with the same kWh usage and are well on track to achieve payback in 20 months which is quite phenomenal. Importantly, by reducing energy consumption, Powerstar is also helping PALRAM’s commitment to help conserve the environment.” Dr Alex Mardapittas, managing director of EMSc and the man responsible for the development of the
Powerstar voltage optimisation range, says that the technology is now more efficient than ever and hopes more people will look at the various VO options available as an effective means of reducing CO2 emissions and costs in an ever-changing climate, both financially and environmentally.
“Many organisations have yet to take
steps to reduce their energy consumption and emissions associated with their operations. It is vital that businesses learn to embrace these new technologies and adopt a new way of thinking if they are to remain profitable and meet government energy efficiency targets.”
