Carrier Introduces Next Generation Factory-Installed Energy Recovery Option, EnergyX®, on Centurion® Rooftop Unit

INDIANAPOLIS, IND., March 22, 2010 – Carrier Corp., a unit of United Technologies Corp. (NYSE:UTX), has introduced the next generation of its factory-installed energy recovery system, EnergyX, on its Centurion rooftop unit, complete with environmentally sound Puron® refrigerant. EnergyX is the latest in a long line of innovative energy-efficient packaged solutions produced by Carrier.

The EnergyX system offers several important benefits, including the ability to downsize the base rooftop unit while increasing the ventilation air quantity and providing excellent system efficiencies. This factory-installed system has demonstrated Combined Efficiency Factors (CEF) as high as 22 (as calculated per AHRI Guideline V). CEF is the equivalent of an Energy Efficiency Ratio (EER) when the EER is calculated for a rooftop unit and energy recovery system. EnergyX incorporates a high-efficiency, rotary, silica gel desiccant coated, energy recovery wheel that is certified by the Air-Conditioning Heating Refrigeration Institute.

"EnergyX provides several advantages for both the new construction and replacement markets," said John Mix, product manager, Centurion rooftops. "The conventional approach to energy recovery has been to use separately installed and powered energy recovery modules, adding cost and complexity to the jobsite in the form of additional curb lengths or support rails and wiring. Because it is factory installed, EnergyX incorporates the tremendous benefits of energy recovery: high system efficiencies, variable-speed blowers, and additional capacities, into a unit extending no more than 26 inches from the standard Centurion system. No additional curb or rail support is needed."

Greg Alcorn, vice president of sales and marketing for Carrier Commercial Unitary Systems, added, "Carrier is proud to offer a factory-installed solution for energy recovery via the EnergyX technology, which is available on all sizes of Centurion packaged rooftop units, ranging from 2 to 25 tons. Because EnergyX provides several application benefits including ease of installation, we are confident that this technology will be widely favored by building owners, contractors and engineers."
