Mitsubishi PLA-AE12NL – 12,000 BTU/H Ceiling Cassette Indoor Unit

Enhance comfort and airflow control in any space with the Mitsubishi PLA-AE12NL, a premium 12,000 BTU/H ceiling-cassette indoor unit engineered for quiet operation, intelligent air distribution, and flexible integration with commercial and residential ductless systems.

Powerful & Efficient Performance

The PLA-AE12NL delivers 12,000 BTU/H of nominal cooling capacity and 14,000 BTU/H of nominal heating capacity, ensuring dependable year-round comfort. Designed for ductless and light commercial applications, this cassette uses a high-efficiency DC fan motor with multiple airflow stages (370/460/490/530 CFM) to optimize air movement based on real-time conditions and comfort needs.

Advanced Comfort Control with 3D i-see Sensor®

Equipped with Mitsubishi Electric’s innovative 3D i-see Sensor®, the PLA-AE12NL scans the room to map temperature variations, occupant location, and thermal patterns. It automatically adjusts airflow and temperature output to improve comfort and reduce unnecessary energy usage. This intelligent system helps maintain exceptional climate control in retail areas, offices, classrooms, conference spaces, and other high-traffic environments.

Quiet, Clean & Flexible Operation

Operating as quietly as 26 dB(A), the PLA-AE12NL ensures minimal noise disturbance, even in sound-sensitive areas. Its easy-to-clean washable filter simplifies maintenance, and optional high-efficiency filtration is available for enhanced air quality. The unit includes a built-in condensate lift mechanism and offers knockouts for outside-air intake and branch ducting, giving installers flexibility to adapt to project requirements.

Compact, Ceiling-Ready Design

With a footprint of 33-1/16″ × 33-1/16″ × 10-3/16″ and a lightweight build of just 46 lbs, this cassette is engineered for space-efficient installations. Its subtle, modern design integrates seamlessly into suspended ceilings while providing uniform, 360° airflow distribution through individually adjustable vanes.

Smart Controls & System Compatibility

The PLA-AE12NL supports a wide range of control options—wired, wireless, app-based, and third-party interfaces—including compatibility with the kumo cloud® Comfort App, MA remote controllers, RedLINK wireless controls, and BAS interfaces such as BACnet or Modbus (with appropriate adapters). Whether integrating into a multi-zone VRF setup or a single-zone ductless system, this unit offers broad compatibility and installation flexibility.

Reliable Refrigerant & Piping Configuration

Using R454B refrigerant, the unit pairs with outdoor systems via 1/4″ liquid and 1/2″ gas line connections. A 1-1/4″ drain outlet supports efficient condensate management. Designed for modern system requirements, the PLA-AE12NL fits seamlessly into both retrofit and new-construction ductless applications.

Built for Light Commercial Performance

This model is specifically designed for light commercial environments, providing advanced airflow options for both high and low ceiling applications as well as up-and-down swing mode for improved circulation. Its versatile performance makes it ideal for lobbies, retail stores, open offices, meeting rooms, and similar spaces requiring dependable year-round climate conditioning.
