The Hitachi SmartFlex Variable Refrigerant Flow (VRF) Gen II offers a re-engineered outdoor unit line with an operating range. It also offers a wider selection of single module sizes and an indoor unit line, which includes: re-engineered ducted units with greater static pressure; a full range of multi-port changeover boxes for heat recovery systems; and enhanced controllers.
The line is able to cool down to an ambient outdoor temperature as low as -4F with the low ambient kit, and as high as 122F. The heating operating range extends from an ambient outdoor temperature of -13F to 59F. 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.
The new lineup 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.
