Mitsubishi Electric 30,000 BTU Hyper Heat Tri Zone Condenser Ductless Mini Split Heat Pump R454B Refrigerant | MXZ-3D30NLHZ

Product Summary

The Mitsubishi Electric MXZ-3D30NLHZ is a Hyper-Heating INVERTER® multi-zone heat pump outdoor unit rated at 28,400 BTU/h for cooling and heating. Designed to connect to up to three compatible indoor units, it supports multi-room conditioning from one outdoor platform. The system uses R454B refrigerant and an inverter-driven compressor to generate the precise capacity needed to maintain the selected temperature set point. Cooling efficiency is listed up to 20 SEER2 in non-ducted configurations, with a listed 10 HSPF2 (IV) for heating efficiency. Rated sound pressure is 56 dB(A) in cooling and 58 dB(A) in heating, supporting outdoor placement near occupied spaces. This outdoor unit can be paired with compatible ducted and non-ducted indoor unit types to build the zone layout that matches the application.

The MXZ-3D30NLHZ is built for variable-load performance, using inverter control to modulate capacity instead of cycling at fixed stages. Maximum cooling capacity is listed up to 30,000 BTU/h depending on the connected indoor unit configuration, with a minimum capacity of 11,600 BTU/h. At 95°F cooling conditions, rated power input is listed at 2,470 W (non-ducted) and maximum power input up to 3,550 W (non-ducted). Efficiency is listed up to 11.50 EER2 (non-ducted) and COP up to 3.50 at 47°F. Airflow rate is listed at 2,239 CFM in cooling and 2,378 CFM in heating to support heat exchange during multi-zone operation. These published ranges help size the system for mixed loads where zones may not call at the same time.

Control precision is supported by the unit’s stated thermal differential of 1°F, which is intended to hold closer temperature control around the set point. In a multi-zone application, each connected indoor unit operates as a separate zone for room-by-room adjustment. The outdoor unit includes fan motor overheating and voltage protection to support stable outdoor fan operation. Refrigeration safeguards include high-pressure protection to help prevent abnormal pressure events. Compressor safeguards include thermal protection and overcurrent detection to reduce the risk of damage during demanding operation. These protections are designed to help keep the system operating within intended electrical and refrigeration limits.

Comfort is supported by both modulation and acoustics, with sound pressure levels listed at 56 dB(A) in cooling and 58 dB(A) in heating. Variable-speed operation helps smooth output by adjusting capacity rather than repeatedly starting and stopping at full load. This steadier approach can reduce noticeable temperature swings during part-load operation in multi-zone applications. Listed airflow performance supports consistent heat transfer when multiple indoor units operate simultaneously. Hyper-heating performance is listed as 100% heating capacity at 5°F and 75% at -13°F, helping maintain comfort during cold snaps. A built-in base pan heater supports winter operation by helping manage ice in the base area.

The MXZ-3D30NLHZ is a practical fit for homes and light commercial spaces that need efficient conditioning across several rooms without multiple outdoor units. It supports layouts such as single-family homes, condominiums, townhomes, and multi-family units where zoning and outdoor space are limited. Connecting up to three indoor zones helps tailor comfort for bedrooms, living areas, basements, or additions with different exposure and occupancy patterns. The unit supports non-ducted, mixed, and ducted application categories, providing flexibility for retrofit and new construction planning. Published cooling and heating performance metrics support selection for a range of climates and load profiles. Because the zoning is built around the connected indoor units, the system can scale comfort where it is needed most.

Value and reliability are supported by layered electrical and refrigeration protections intended to reduce stress on core components. The unit lists compressor thermal protection, compressor overcurrent detection, and high-pressure protection to help prevent damaging operating conditions. Fan motor overheating and voltage protection add a further safeguard for outdoor fan operation. Seacoast protection on the heat exchanger and base panel is rated for 2,000 hours in ASTM B117 testing to support corrosion resistance in coastal environments. A built-in base pan heater supports operation during freezing conditions by helping manage water and ice accumulation. These design elements support serviceability and long-term performance in demanding outdoor installations.

As a complete multi-zone heat pump solution, the Mitsubishi Electric MXZ-3D30NLHZ delivers 28,400 BTU/h rated capacity with efficiency ratings up to 20 SEER2 and 10 HSPF2 (IV) in non-ducted configurations. It consolidates up to three indoor zones onto a single outdoor unit, supporting room-by-room comfort control and flexible system layouts. Hyper-heating performance at low outdoor temperatures helps maintain heating capacity when it matters most. Quiet sound ratings and inverter modulation support residential-friendly operation while still delivering strong airflow for heat exchange. R454B refrigerant and protective monitoring functions align the system with modern refrigerant and equipment expectations. For D2C shoppers and wholesale buyers, it delivers a scalable way to build a multi-room comfort system with one outdoor unit and compatible indoor zones.
