ELL 100861 is the silver indoor unit of the Front air-to-air heat pump, a single-split inverter-controlled system operating on R32 refrigerant. It provides both cooling and heating for a single conditioned space and pairs with its matching outdoor unit. Inverter modulation adapts compressor speed to load, supporting stable room temperature and reduced cycling losses. Typical applications include residential living rooms, home offices and small commercial spaces requiring comfort conditioning year-round.
