Carrier Expands WeatherExpert™ Rooftop Line to 23 Tons

Carrier has released the second size range of its highest efficiency commercial rooftops, the WeatherExpert™ Series, which includes models from 6- to 23-tons; adding to a current model line-up that includes 3- to 5-ton units.  The WeatherExpert line boasts industry-leading Integrated Energy Efficiency Ratio (IEER) ratings up to 21.0 that exceed the Consortium of Energy Efficiency (CEE) tier II performance criteria, which many utilities use for rebates. The product line also meets or exceeds all current ASHRAE 90.1 - 2010 and Energy Star® energy requirements, with some models exceeding standards by more than 84 percent. Carrier, 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).

Similar to other models in the Carrier Weather Series line, the WeatherExpert  6- to 23-ton units were designed to maintain product familiarity by taking advantage of common parts from existing Carrier rooftop designs and were designed in collaboration with customers. Carrier also plans to release its 75- to 150-ton WeatherExpert units later this year. 
“The WeatherExpert rooftop units won recognition in the Cooling Category for the 2013 AHR Expo Innovation Awards Competition, a testament to the advances made as a result of customer collaboration,” said Greg Alcorn, vice president, commercial sales and marketing, Carrier. “With the addition of these 15 models this summer, Carrier will have its most comprehensive and efficient rooftop line ever, with units ranging from 3- to 150-tons.”

The new WeatherExpert 6- to 23- ton units will be available with three stages of capacity control utilizing scroll compressors and electronically commutated motor (ECM) outdoor fan motors. In addition, the indoor fan motor is controlled by Carrier’s Staged Air Volume (SAV™) system to precisely match fan operation to the staging compressors. These units are available in gas/electric, electric/electric or cooling only, and offered with a range of factory options, such as energy-efficient air economizers, smoke detectors, and much more.

“The WeatherExpert units deliver optimal comfort and energy savings at both full- and part-load conditions,” added Alcorn. “Our comfort-control logic operates the multi-stage system to provide what our customers are looking for – smart, efficient operation.”

All WeatherExpert units feature Puron® refrigerant (R-410A), provide easy access for routine maintenance, are supported by Carrier’s eDesign Suite and integrate with Carrier’s i-Vu® system controls.
