Mitsubishi Electric SVZ-AP48NL & SUZ-AK48NLHZ 48,000 BTU 18.1 SEER2 Multi-Position Ducted Air Handler Hyper-Heating H2iSystem - R454B - SVZAP48NL/SUZAK48NLHZ
The Mitsubishi SVZ-AP48NL & SUZ-AK48NLHZ is a powerful 48,000 BTU ducted heat pump system designed to deliver robust year-round comfort in large residential or light commercial spaces. Equipped with Hyper-Heating INVERTER(H2i) technology, it provides 100% heating capacity down to 5°F and continues heating operation down to -13°F, with guaranteed restart at -22°F. This makes it ideal for cold-climate applications requiring reliable performance even in extreme winter conditions.
The SVZ-AP48NL indoor air handler supports multi-position installation and selectable static pressure for tailored airflow, while fiberglass-free insulation improves efficiency and reduces condensation. A unique blow-through design simplifies coil maintenance, and the positive pressure cabinet ensures air leakage of less than 1% at 1.0 in.WG.
The SUZ-AK48NLHZ outdoor unit features Blue Fin anti-corrosion coating, a built-in base pan heater, high-performance grooved piping, and Hot-Start Technology to prevent cold air drafts at startup. With inverter-driven capacity control, Joint Lap DC Motor technology, and Pulse Amplitude Modulation, this system achieves superior efficiency, durability, and whisper-quiet performance.
