Mitsubishi Electric Trane HVAC US (METUS) has announced a lineup of redesigned PFKY wall-mounted indoor units in capacities from 4,000 to 18,000 BTU/H. The small, quiet and smart units bring sleek aesthetics and efficiency to commercial buildings. Newly designed for small spaces, PKFY wall-mounted indoor units deliver optimized comfort and efficiency in light commercial and commercial applications. The units operate efficiently and are whisper-quiet. PKFY units connect to CITY MULTI® R2-Series, Y-Series, WY-Series, WR2-Series and S-Series VRF zoning systems. Designed to vary compressor motor speeds and capacity according to heating and cooling loads, these systems use only the minimal amount of energy needed to maintain a zone’s desired set point, thus saving energy and operating costs.
