Mitsubishi PLA-AE48NL & PUZ-AK48NLHZ 48,000 BTU 20.1 SEER2 Four-Way Ceiling Cassette Hyper Heat Heat Pump System (w/ Grille) - R454B

Mitsubishi PLA-AE48NL & PUZ-AK48NLHZ: 48,000 BTU Ceiling Cassette Hyper-Heat Pump System

The Mitsubishi PLA-AE48NL indoor cassette paired with the PUZ-AK48NLHZ Hyper-Heat outdoor unit delivers powerful, high-capacity heating and cooling with 48,000 BTU of output. Engineered for large commercial and residential spaces up to ~2,400 sq ft, this system is ideal for lobbies, conference centers, classrooms, restaurants, retail environments, and expansive living areas requiring strong performance, quiet operation, and reliable cold-climate heating.

The indoor cassette features Mitsubishi’s advanced 3D i-see Sensor®, which analyzes heat signatures, temperature gradients, and room occupancy to automatically fine-tune airflow and output. Individual vane control, high/low ceiling airflow modes, and swing-mode distribution provide uniform cooling and heating across large rooms. With a slim 33" × 33" ceiling footprint, built-in condensate lift, and available knockouts for fresh-air intake and branch ducting, the unit installs cleanly in demanding light commercial environments. The washable filter and filter indicator also simplify ongoing maintenance.

The PUZ-AK48NLHZ utilizes Hyper-Heating INVERTER® technology to deliver rapid heating start-up and maintain strong performance down to –13°F, averaging 80% heating capacity in extreme cold. A built-in base pan heater protects the unit during freezing conditions, while the inverter-driven compressor provides precise efficiency and smooth operation. Seacoast protection—including 2,000-hour ASTM B117 rated components and Blue Fin coil coating—ensures long-term durability in coastal or industrial environments. The unit arrives pre-charged for up to 100 ft of line length, and features pressure/temperature protection systems, wide operating ranges, and reliable low-ambient heating and cooling.

Despite its high capacity, the system operates quietly with indoor sound levels starting at 34 dB(A). It supports flexible control options including wired and wireless controllers, third-party thermostat integration, and Mitsubishi’s Comfort App for remote operation. With a SEER2 rating of 20.1 and robust heating output—up to 60,000 BTU at 47°F and 52,000 BTU at 5°F—this Hyper-Heat system provides dependable, efficient year-round comfort for large, high-demand spaces.
