Mesa Energy Systems Wins Danfoss EnVisioneer of the Year Award


IRVINE, Calif. — Danfoss, a manufacturer of high-efficiency electronic and mechanical components and controls for air-conditioning, heating, refrigeration, industrial and water systems, announced EMCOR Services Mesa Energy Systems, of Irvine, Calif., is the winner of the sixth annual EnVisioneer of the Year award.

Launched in 2010, the EnVisioneer of the Year award competition recognizes North American end users, municipalities, building owners or original equipment manufacturers that have introduced a new product, opened a new facility or invested in a building or system upgrade using Danfoss products or solutions to realize significant energy and/or environmental savings.

EMCOR Services Mesa Energy Systems, a licensed commercial HVAC contractor offering HVAC maintenance and services, building automation systems, commercial refrigeration repair and chiller services, has used energy-efficient variable speed, oil-free, magnetic-bearing technology in a variety of retrofit applications, including the MacArthur Plaza commercial office building in Irvine, Calif.

To combat increasing maintenance and energy costs in the nine-story, 154,530-square-foot structure, Mesa Energy Systems replaced 400 tons of existing reciprocating compressors with six oil-free centrifugal compressors. In addition to boosting the HVAC system's cooling capacity to 500 tons, the solution also provided the flexibility to operate efficiently at loads ranging from 50 to 500 tons. The new system dramatically reduced energy consumption, resulting in the building owner reporting energy savings, a shortened payback period, and the acquisition of utility incentives. The system design and implementation also won the ASHRAE Southern California Technological Design Award.

Mesa Energy Systems also has experienced similar success in other retrofit projects using energy-efficient variable speed, oil-free, magnetic-bearing technology, including in a data center for a worldwide telecommunications provider that included the installation of eight 300-ton air-cooled chillers using oil-free centrifugal compressors. In combination with new chilled water pumps, flow meters and DDC controls, the data center reported substantial energy savings and utility incentives, which they cited as contributing to a payback period of less than three years.

"These examples reflect EMCOR Services Mesa Energy Systems' winning approach to energy efficiency, especially in the retrofit market," said Lisa Tryson, director, corporate communications, Danfoss. "They prove that, when properly applied, innovative technology can breathe new, more energy-efficient and cost-effective life into old buildings and produce impressive results."
