Mitsubishi Electric Trane HVAC US (METUS) has expanded the S-Series (PUMY) air-source heat pump outdoor unit to include Hyper-Heating INVERTER® (H2i®) technology in select models. Part of the CITY MULTI® family of products, the PUMY is a single-phase heat pump suited for light commercial or large residential applications.
The addition of H2i technology, now available in PUMY P36 (3-ton) and P48 (4-ton) models, allows the units to provide year-round comfort in cold climates and extreme temperatures. Hyper-heating units offer up to 100% of rated heating capacity at 5ºF and perform at 78% of rated capacity in temperatures as low as -13ºF.
Other enhancements to PUMY units include improved efficiency. Each unit is equipped with an INVERTER-driven compressor that optimizes energy usage for the space, reducing energy waste. The units have also met ENERGY STAR® certification standards. Additionally, PUMY systems use the CITY MULTI Controls Network (CMCN) and can heat or cool up to 12 individual zones with many options for indoor unit sizes and styles.
