Johnson Controls Launches Next Generation of Variable Refrigerant Flow Technology

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.
