The next generation of the company’s factory-installed energy recovery system, EnergyX, is available on its Centurion rooftop unit. The system offers 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 Air-Conditioning, Heating, and Refrigeration Institute (AHRI) Guideline V. According to the manufacturer, 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 AHRI. The energy recovery system incorporates 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. It is available on all sizes of Centurion packaged rooftop units, ranging from 2 to 25 tons.
