Johnson Controls launched the Hitachi SmartFlex Variable Refrigerant Flow (VRF) Gen II, the second generation of VRF HVAC equipment for the North American market. Hitachi SmartFlex VRF Gen II offers many enhancements, including a re-engineered outdoor unit line with an improved operating range and a wider selection of single module sizes, an indoor unit line that includes re-engineered ducted units with greater static pressure, and a full range of multi-port change-over boxes for heat recovery systems and enhanced controllers.

The line has an extended operating range with cooling down to an ambient outdoor temperature as low as minus 4°F with the low ambient kit (for server rooms or other areas that require cooling year-round) and as high as 122°F. The heating operating range extends from an ambient outdoor temperature of minus 13°F to 59° F. This enables customers to select highly efficient VRF systems for more projects, including those with demanding requirements.
