    Fujitsu General America introduces the AIRSTAGE J-7s line of VRF heat pumps. The new models, which use the low-GWP (Global Warming Potential) refrigerant R-32, offer improved efficiency in more compact cabinets than Fujitsu’s previous single-phase offerings.

    The J-7s line includes two-, three-, and four-ton models for commercial and light commercial applications, featuring certified energy efficiency ratings up to 15.7 EER2, 22.2 SEER2, 11.3 HSPF2, and 4.64 COP2. The units operate reliably in outdoor temperatures from -15 to 70 degrees F. in heating mode and 23 to 122 degrees F. in cooling mode. A built-in base pan heater ensures reliable winter performance. Most models are ENERGY STAR and ENERGY STAR Cold Climate certified. Sound levels are as low as 52 dB(A).
