Mitsubishi Single Zone Four-Way Ceiling Cassette Systems

A room with a drop ceiling gives you a neat option most people overlook. Instead of hanging a unit on the wall, you can swap one ceiling tile for a cassette and let it push air evenly in every direction. A Mitsubishi Single Zone Four-Way Ceiling Cassette does exactly that. It sits flush in the ceiling, and from below it looks like a clean square grille.

Mitsubishi's SLZ cassette is sized to fit a standard 2' x 2' suspended ceiling grid, and it can also go into a drywall ceiling with an access panel. It pairs one-to-one with an SUZ outdoor heat pump for a single room system. For a mid-size room, the Mitsubishi SLZ-AF12NL 12,000 BTU four-way cassette is a popular indoor unit.

•   Works in drywall ceilings with an access panel

•   Heating and cooling for one room

How a Four-Way Ceiling Cassette Works

The cassette body sits above the ceiling, and only the grille shows. Air gets pulled in through the center and pushed out through four vanes, one on each side. That spread is why a single cassette can keep a room even, without the warm corner and cold corner problem some wall units leave behind.

A refrigerant line set connects the cassette to the SUZ outdoor heat pump. The inverter compressor adjusts its speed to the room's actual needs, so it settles into a steady pace instead of constantly switching on and off. Temperatures stay stable and energy use stays low.

72 Airflow Patterns

Each of the four vanes can be set on its own. Mitsubishi gives you 72 different airflow patterns, so if the cassette sits near a wall or a desk, you can close off or redirect a vane. An optional 3D i-see Sensor grille scans for people and shifts airflow toward or away from them.

•   Four independent vanes for custom airflow

•   Optional 3D i-see Sensor for occupancy based comfort

Where a Mitsubishi Single Zone Four-Way Ceiling Cassette Fits Best

Basements with drop ceilings, home offices, small retail shops, waiting rooms, and open living areas all work well. A Mitsubishi Single Zone Four-Way Ceiling Cassette is especially handy in rooms where wall space is taken up by windows, shelves, or artwork. For long, narrow rooms, a one-way model like the Mitsubishi MLZ-KX18NL one-way ceiling cassette may push air across the space better.

Light commercial spaces use them a lot too. Small offices and restaurants with suspended ceilings can add a Mitsubishi Single Zone Four-Way Ceiling Cassette without cluttering the walls or changing the look of the room.

Getting the Size Right

The SLZ lineup covers 9,000 to 18,000 BTU. Start with square footage, then factor in ceiling height, windows, sun exposure, and how many people use the space. A busy office with computers and big windows needs more capacity than a quiet den of the same size. Avoid oversizing, since that leaves the room feeling damp.

•   Match capacity to room size, occupancy, and sun

•   Stay close to the real load instead of going bigger

Key Features of the SLZ Lineup

These cassettes are quiet, running as low as 24 dB(A). They include a built-in condensate lift that raises drain water up to 33 inches, which helps a lot in finished ceilings. Most systems carry ENERGY STAR certification, and the SUZ outdoor units include Blue Fin anti-corrosion coating. Hyper-Heating outdoor versions are available for cold climates.

For larger rooms up to about 750 square feet, the Mitsubishi SLZ-AF18NL 18,000 BTU four-way cassette gives you the most capacity in the lineup. Every Mitsubishi Single Zone Four-Way Ceiling Cassette here uses R454B refrigerant.
