/PRNewswire/ -- The new Carrier
10-ton unit exceeds the parameters of the recent Department of Energy (DOE) Rooftop Unit (RTU) Challenge, providing an Integrated Energy Efficiency Ratio (IEER) of 20.8 - more than 15 percent more efficient than the required minimum of 18.0 IEER.
, the world's leader in high technology heating, air-conditioning and refrigeration solutions, is a part of UTC Climate, Controls & Security, a unit of United Technologies Corp. (NYSE: UTX).
In an effort to spur the market introduction of cost-effective, high-performance commercial rooftop air conditioners, the DOE created the RTU Challenge, enlisting manufacturers to develop a 10-ton unit that meets the 18.0 IEER-specifications by
April 1, 2013
. The DOE focused on rooftop units that are used in nearly half of all commercial cooling systems in the U.S. If all the 10-ton units currently sold nationwide were built using this new 18.0 IEER criteria, businesses would reduce energy use by half, compared to current equipment, saving about
annually in energy costs.
As an innovator and market leader, Carrier embraced the RTU Challenge and committed to the energy savings initiative more broadly with its entire line of WeatherExpert models ranging from 3- to 23-ton units reaching a high-IEER rating of 21.0, making the WeatherExpert one of the most efficient packaged rooftop units available.
"When the DOE announced its RTU Challenge, we accepted immediately and enthusiastically," stated
, vice president, commercial sales and marketing, Carrier. "Carrier is committed to developing energy efficient solutions, so this challenge aligned perfectly with our priorities and market position. The DOE has taken a big step forward in improving the efficiency of the commercial cooling industry with the RTU Challenge, and Carrier is proud to be at the forefront of that movement."
