Johnson Controls has launched the Hitachi SmartFlex™ VRF Gen II, the second generation of VRF HVAC equipment for the North American market. The company says the Hitachi SmartFlex™ VRF Gen II offers significant enhancements including a re-engineered outdoor unit line with a greater operating range and a wider selection of single module sizes and an indoor unit line that includes re-engineered ducted units with greater static pressure. The product also includes 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 -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 -13°F to 59° F. This extended operating range enables customers to select highly efficient VRF systems for more projects including those with demanding requirements. For further flexibility, single modules are now available in 6-, 8-, 10-, 12-, 14-, and 16-ton capacities enabling heat pump or heat recovery systems up to 36 tons to be configured more economically.
In addition to offering higher-static ducted indoor units in multiple sizes, the new lineup also includes non-ducted units in more capacities. This enables equipment to be precisely sized to project specifications. The line offers a full line of change-over box options: single-port change-over boxes in two capacities and multi-port change-over boxes with 4, 8, and 12 ports for more heat recovery system design options.
