Delta’s High-efficiency Medium Voltage Drives (MVD) Enhance Energy Savings

by up to 54% in a Refuse Incineration Plant in Taiwan

TAIPEI, Taiwan — Delta, a global leader in power and thermal management solutions, announced today its medium voltage drive (MVD) technology has successfully enabled annual energy savings in motors of three induced draft (ID) fans in a refuse incineration plant in Taiwan by up to 54%. Such impressive improvement ratio, achieved through the energy-efficient motor speed control realized by the three units of Delta’s MVD1000 series drives, translates into annual savings of approximately 1.7 million kWh in electricity consumption for the first unit installed and to a valuable investment payback period below one year.

Victor Cheng, General Manager of Delta’s Power System Business Group (PSBG) remarked, “Delta has leveraged its core competence in high-efficiency power electronics and commitment to R&D-based innovation to become the only manufacturer of cutting-edge branded MVDs in Taiwan because the industrial sector is one of the most energy-intensive fields in the world, and therefore, pivotal in the crusade for lower carbon emissions. We are delighted to see that such efforts are paying off and look forward to nurturing energy efficiency in a wide spectrum of applications within the metallurgy, cement, power generation, mining and oil & gas fields with our MVD technology.”

Delta’s MVD1000 boasts input power quality with up to 97% energy efficiency, multi-pulse input rectification and a built-in PID controller to improve productivity and energy savings in 3.3~11kV motors operating in industrial fans and pumps, in contrast with the relatively inefficient conventional damper or valve control. Lower stress on motors resulting from that energy-efficient speed control can also enhance the lifetime of crucial equipment and minimize maintenance time and costs. Delta also offers value-added services that help customers assess ROI and energy savings estimations before actual system integration.

Other sites in Taiwan have recently obtained relevant benefits from the utilization of Delta’s MVD1000. A cement manufacturing plant experienced up to 51% annual energy savings through the management of motor speed in a rotary kiln cooling ID fan while an international airport implemented a compact all-in-one MVD solution that decreases the input harmonics in the chiller equipment of its air conditioning system.
