The Zero 2 Zone Ductless Multi-Zone Hyper Heat Pump System (Z4SOV-18HDMB-USHH) is an advanced and energy-efficient HVAC solution designed for precise climate control across two rooms. With a total capacity of 18,000 BTU, this system includes two 9,000 BTU indoor units, making it ideal for bedrooms, offices, and small living areas.
This multi-zone system allows a single outdoor unit to support multiple indoor units, reducing installation complexity and saving outdoor space. Each indoor unit operates independently, allowing personalized temperature control for each zone.
Built with next-generation R454B refrigerant, the system delivers high efficiency with a significantly lower global warming potential (GWP), making it an environmentally responsible choice.
