MULTI 21+ Systems

One of today’s most advanced inverter-driven ductless heat pump systems, our acclaimed MULTI21+ systems will facilitate multiple room continuity for both heating and cooling. The MULTI21+ zone system is a synthesis of indoor units that can be mixed and matched for use in up to five zones, but only one zone is required for start-up– ideal for residential and light commercial application. Ecologically engineered to achieve up to 22 SEER, the MULTI21+ operates with G-10 inverter technology that significantly reduces energy consumption by adjusting the compressor speed according to the total building load. Eco-friendly by design, the Multi21+ uses friendly R401A refrigerant. The MULTI21+’s intelligent engineering means a high-efficiency system with world-class performance that provides comfort, uncompromising personal style, and tremendous energy savings.
