Danfoss Recognizes MultiStack as the 2nd Annual EnVisioneer of the Year

Danfoss recognized MultiStack LLC, of Sparta, WI, as the winner of the second annual "EnVisioneer of the Year" award competition, for its success in implementing energy-efficient practices. The award was presented on October 5, 2011 in Washington, D.C., following the annual Alliance to Save Energy's Stars of Energy Efficiency black-tie gala.

MultiStack installed two MultiStack chillers at Valley High School, Las Vegas, NV. The installation included eight Danfoss Turbocor compressors, four Danfoss VLT® variable frequency drives and the MultiStack FlexSys controller, which incorporates Danfoss Turbocor software.

By switching to the magnetic levitation-powered chillers and a central plant control system, school administrators hoped to reduce energy use at the 45-year-old building by 50%. In fact, the school exceeded its goal by 20%, reducing energy consumption from 1.5 kW/ton to .443 kW/ton.

"We are excited to recognize MultiStack's winning approach to energy efficiency," said John Galyen, president, Danfoss North America. "This application is particularly interesting, because it demonstrates the impressive savings that can be achieved in existing buildings by investing in and applying energy-efficient technology available on the market today. It's proof that upgrades that can be made right now will have a big impact on the future of the building and the environment."

The "EnVisioneer of the Year" award competition was launched in 2010 by Danfoss to recognize end users, building owners and original equipment manufacturers (OEMs) that exemplify the Danfoss EnVisioneering core values and have used Danfoss products to realize significant energy and/or environment savings.
