Key Features and Benefits of the Pioneer 18,000 BTU Quantum Ultra Ceiling Concealed Mini-Split

• Ultra-Slim Profile: At less than 8 inches high, the indoor air handler installs easily above drop ceilings, preserving valuable space and architectural aesthetics.
• High Efficiency: Lower your operating costs with an ultra-efficient heat pump that has a 21 SEER2 cooling efficiency rating and an 8.1 HSPF2 heating efficiency, which meets today’s strict performance standards.
• Inverter Technology: This model’s variable speed inverter compressor maintains precise temperatures and quieter sound levels by only ramping up the compressor when it’s needed.
• Four Operating Modes: Switch between cooling, heating, dehumidification, and ventilation modes to handle seasonal changes with one system. Operation can be directed up, down, left, or right using motorized louvers.
• DC Fan Motor: Enjoy a consistent and powerful airflow regardless of the duct length and static pressure without exceeding 41 dB, thanks to the efficient and quiet DC motor and blower wheel design.
• Dual Air Intake: You can choose to install the air handler with either rear or bottom air intake configurations to match your duct layout and simplify installations.
• Built-In Drain Pump: The Quantum Ultra’s air handler features a built-in condensate pump that can lift condensate up to 30 inches. The pump can be disabled if you’d prefer to use a gravity drain instead, and the system will automatically shut down if it senses a clog in the line.
• R-454B Refrigerant: The Pioneer Quantum Ultra Concealed Mini-Split uses R-454B, a lower-GWP refrigerant that helps meet environmental regulations and goals, without sacrificing performance.
• Wired LCD Controller: Wall-mount the included Pioneer 540L Wired Controller where it is convenient for daily adjustments and a clear view of the system’s status. It can also be controlled by Pioneer’s Pioneer Airlink app, 3rd party voice control platforms, and a handheld wireless remote.
• Low Temperature Operation: This model heats in outdoor temperatures as low as -13 degrees F, and cools in temperatures as high as 131 degrees F.
• Auto-Restart Memory: If the power is interrupted, the system resumes the previous settings automatically.
• Line Set Included: This model includes the 16-foot 1/4 x 1/2 line set that is required for installation.

Hidden Climate Control

Choosing the Pioneer Quantum Ultra ceiling concealed mini-split means your occupants experience comfortable airflow without ever seeing the air handler. The Quantum Ultra’s low-profile chassis leaves only grilles in view, offering a clean architectural finish that appeals to designers and owners alike. Because the system can be ducted to multiple rooms, you can condition multiple rooms, open plan areas, and offices, using a single concealed air handler while keeping noise and visual impact to a minimum.
