Fujitsu General America introduces the AIRSTAGE J-7s line of VRF heat pumps. Utilizing the low GWP R-32 refrigerant, the new models offer installation flexibility, efficiency and more compact cabinets than Fujitsu’s previous single-phase offerings. The J-7S line includes two-, three- and four-ton models designed for commercial and light commercial applications. Certified energy efficiency ratings reach up to 15.7 for EER2, 22.2 for SEER2, 11.3 for HSPF2, and 4.64 for COP2. Optimized for a wide range of climates, the systems operate reliably in outdoor temperatures from -15°F to 70°F in heating mode, and 23°F to 122°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. The new heat pumps feature a 16% smaller footprint than earlier models. A single outdoor unit supports up to 12 indoor units for versatile zoning. The four-ton unit allows a maximum total equivalent pipe length of 393 feet. A 50%-130% system connection ratio on three- and four-ton models enhances load matching for varying project needs. Factory refrigerant charge is limited to 5.95 pounds across all models, simplifying regulatory compliance. Sound levels remain as low as 52 dB(A).
