Innovative solution provides new hyper-heating capacity option while advancing sustainability with low‑global warming potential (GWP) refrigerant
Mitsubishi Electric Trane HVAC US LLC (METUS), a leading supplier of all-electric, all-climate Ductless and Ducted Mini-split and Variable Refrigerant Flow (VRF) heat pump and air-conditioning systems, today announced the launch of the Mitsubishi Electric Single‑phase SMART MULTI® 5‑ton Hyper-Heating INVERTER® (H2i) Outdoor Unit (MXZ-SM).
With the addition of the new 5‑ton Hyper‑Heating INVERTER® (H2i) unit, METUS now offers a complete SMART MULTI lineup, allowing engineers, contractors, and building owners to specify right‑sized solutions across a broader range of project needs in colder climates. The system’s H2i technology offers reliable, year‑round comfort even in extreme climates. The new unit delivers 100% heating capacity at 5° F and 80% heating capacity at -13° F, with a heating thermal lock‑out at -24° F. Flash injection technology further enhances compressor performance during cold temperatures.
METUS already offers a 5-ton standard model.
Designed with a low-GWP refrigerant, the new SMART MULTI outdoor unit incorporates built‑in safety features, including shut‑off valves, which meet A2L and UL requirements.
The 5-ton H2i outdoor unit supports multi‑zone configurations, connecting to multiple indoor units to deliver personalized comfort across multiple spaces. Indoor unit versatility is a key advantage of the system, with support for a connected capacity range of 50% to 130% and compatibility with M‑ and P‑Series indoor units (up to eight units) and CITY MULTI® indoor units (up to 12 units).
To support customized operation and easier service, the unit includes enhanced dipswitch configuration options. A USB recorder capable of storing up to two weeks of operational data also streamlines troubleshooting.
All outdoor units include factory‑installed Seacoast Protection, featuring a coated base panel and a Blue Fin–coated outdoor heat exchanger. This anti‑corrosion treatment helps protect against salt, sulfur, and other airborne contaminants and is rated for 2,000 hours in accordance with ASTM B117 standards.
All system combinations are ENERGY STAR® Cold Climate and NEEP certified, with select combinations also meeting ENERGY STAR requirements.
“Contractors are looking for HVAC solutions they can trust from design through long‑term operation,” said Brinnon Williams, Vice President of Residential Business, METUS. “The addition of a 5-ton H2i outdoor unit to the SMART MULTI platform reinforces our focus on flexibility, reliability, and real‑world performance.”
