Building owners can increase operating efficiency and comfort control with a Carrier EnergyX® energy recovery ventilator (ERV) system, now offered on Carrier WeatherMaster® 48/50HC rooftops. This factory-installed offering pre-conditions the outdoor air before it enters the rooftop unit evaporator coil, and uses building exhaust air as a heat exchange source. As a result, the system, which is fully integrated into the rooftop unit, operates efficiently under a wider range of ambient temperatures. Based on Air-Conditioning, Heating and Refrigeration Institute (AHRI) guidelines, these EnergyX units achieve Combined Efficiency Factors (CEF) of up to 17.0*. Carrier, the world’s leader in high technology heating, air-conditioning and refrigeration solutions, is a part of UTC Climate, Controls & Security Systems, a unit of United Technologies Corp. (NYSE: UTX).

“The EnergyX system provides the potential to reduce costs by downsizing the base rooftop unit while still meeting ventilation requirements. It can also qualify for utility rebates,” stated Greg Alcorn, vice president, commercial sales and marketing, Carrier.

The EnergyX system comes fully integrated as a single packaged product on Carrier WeatherMaster®48/50HC units and uses standard roof curbs for streamlined installation. Units come standard with ComfortLink controls and have a single-point power connection. Additional options include a true wheel bypass economizer and variable-speed energy recovery fans for optimum Demand Control Ventilation (DCV).

Alcorn added, “We started production of the EnergyX system with some of our most popular WeatherMaster sizes (15 to 25 tons), and we will be rolling out the system on 3- to 12.5-ton units in the coming months, so it will be available on the entire WeatherMaster line by spring.”
