The Zero 6 Zone Ductless Multi-Zone Hyper Heat Pump System (Z4SOV-53HDMB-USHH) is a high-capacity, energy-efficient HVAC solution designed for large homes and commercial spaces requiring independent climate control across multiple rooms. With a total capacity of 53,000 BTU, this system includes six 9,000 BTU indoor units, making it ideal for whole-home comfort, multi-room layouts, and office environments.
This multi-zone system allows a single outdoor unit to support up to six indoor units, reducing installation complexity while optimizing outdoor space usage. Each indoor unit operates independently, enabling customized temperature settings for every room.
Built with next-generation R454B refrigerant, the system delivers high efficiency with significantly lower global warming potential (GWP), making it an environmentally responsible and future-ready HVAC solution.
