Fujitsu General has added to its J-Series Airstage VRF line with introduction of the smaller J-IIS series. The J-IIS avails variable refrigerant flow technology for smaller residential, multi-housing and light commercial uses with equipment now available in 3 and 4 ton sizes.
The larger J-II VRF series – introduced earlier with 3, 4 and 5 ton sizes – helped to bridge the gap between its Halcyon multi-zone systems, and larger VRF technology. The J-IIS further enhances the offering with its compact size.
The J-IIS’ shorter height provides easy installation in smaller spaces, or when condensing units are stacked vertically. Also, the J-IIS provides significantly higher efficiency than equivalent single-fan VRF systems.
Both J-II and J-IIS equipment are single-phase Airstage VRF products. Both are designed for superior energy efficiency, provide great year-round comfort, and are easily installed.
Also, both of the J-II and J-IIS are used in the same applications and with the same types of controls. The J-Series VRF systems offer up to 19.8 SEER and 11.4 HSPF, significantly exceeding other equivalent VRF products and rooftop units of comparable size.
Installers can connect up to eight indoor units to each condensing unit and choose from 11 indoor-unit styles to create individually zoned comfort for any size, space or decor. Indoor units range in size from 7 kBtu to 46 kBtu. Fujitsu General’s VRF controls offer additional energy savings and comfort features, including scheduling, sleep timer, economy operation and automatic season changeover.
