Open commercial spaces create a different HVAC challenge from a typical bedroom or living room. Air needs to reach people in multiple directions, equipment should not compete with valuable wall space, and the system needs to stay comfortable without becoming a distraction.
That is exactly where the TOSOT Aoraki Light Commercial Ceiling Cassette is designed to fit. Available in 9,000, 12,000, 18,000, and 24,000 BTU capacities, the ceiling cassette combines the Aoraki platform’s extreme-weather heat pump performance with 360° airflow, quiet operation as low as 27 dB, and a built-in condensate pump.
For offices, restaurants, retail stores, studios, showrooms, and other light-commercial spaces, it brings comfort into the room from above while keeping the HVAC system largely out of sight.
360° Airflow for Open Commercial Spaces
One of the key advantages of a ceiling cassette is its multi-directional airflow.
A traditional wall-mounted mini split delivers conditioned air mainly from one side of the room. In an open commercial space, that can make it harder to distribute airflow evenly across seating areas, workstations, displays, or other occupied zones.
The Aoraki Ceiling Cassette uses 360° airflow, allowing conditioned air to spread outward around the cassette rather than being directed from a single wall.
Positioned near the center of the space, this multi-directional airflow can help reduce noticeable hot and cold spots and provide more balanced comfort throughout the room.
For restaurants, open offices, boutiques, salons, and similar layouts, this is one of the main reasons to choose a cassette over a conventional wall-mounted indoor unit.
Quiet Operation as Low as 27 dB
HVAC noise can matter just as much as temperature in offices, meeting rooms, studios, cafés, and customer-facing environments.
The Ceiling Cassette mini split is designed for quiet operation. It operates at sound levels as low as 29 dB, depending on operating conditions and fan settings.
Combined with its recessed ceiling installation, this allows the system to provide heating and cooling without becoming a dominant visual or acoustic presence in the room. The goal is simple: people should notice the comfort, not the equipment.
Built-In Condensate Pump
Because ceiling cassette units are installed overhead, condensate management becomes an important part of the installation.
During cooling operation, moisture removed from indoor air collects inside the unit and must be drained properly. The Aoraki Ceiling Cassette includes a built-in condensate pump, helping move collected water toward the drainage point instead of relying entirely on gravity.
This gives installers more flexibility when routing condensate lines, particularly in commercial projects where the ideal cassette location may not provide a simple downward drain path.
For suspended ceilings, remodeled spaces, offices, restaurants, and other light-commercial applications, the integrated pump can make installation planning considerably easier.
Proper drain piping, service access, and maintenance are still essential for long-term reliability.
Ultra Heat Performance Down to -40°F
The Aoraki Light Commercial Series is designed for both summer cooling and extreme-cold-weather heating.
Its Ultra Heat technology is engineered for heating operation down to -40°F, extending heat-pump capability into severe winter conditions. Combined with inverter-driven operation, the system can adjust output according to changing demand rather than relying solely on full-on/full-off operation.
This makes the Ceiling Cassette Mini Split suitable for businesses that need year-round heating and cooling across a wide range of outdoor temperatures.
Four Capacities for Different Applications
The Aoraki Ceiling Cassette is available in four capacities:
- 9,000 BTU
- 12,000 BTU
- 18,000 BTU
- 24,000 BTU
The range allows the same ceiling cassette platform to serve different light-commercial applications, from smaller offices and consultation rooms to larger retail, dining, and studio spaces.
The range allows the same ceiling cassette platform to serve different light-commercial applications, from smaller offices and consultation rooms to larger retail, dining, and studio spaces.
Actual capacity selection should be based on a proper heating and cooling load calculation. Factors such as ceiling height, insulation, glass area, solar exposure, occupancy, lighting, equipment, door openings, and local climate can all affect system requirements.

Designed for Spaces Where Appearance Matters
Commercial interiors often need to balance HVAC requirements with design and usable space.
Restaurants may need wall space for décor, while retailers need room for merchandise and signage. Offices, showrooms, and studios may prioritize windows and clean visual lines.
Because most of the ceiling cassette is installed above the ceiling, only the finished panel remains visible inside the room. This helps preserve wall and floor space while creating a more integrated appearance.
Backed by GREE Manufacturing Experience
TOSOT products are backed by the manufacturing experience of GREE, one of the world’s largest HVAC manufacturers.
That manufacturing background brings decades of experience in compressors, inverter controls, heat-pump systems, indoor airflow design, and large-scale HVAC production into the Aoraki platform.
For the Aoraki Light Commercial Series, that foundation supports a product designed not only around headline specifications, but around the everyday requirements of commercial HVAC: airflow, low-temperature performance, installation flexibility, drainage management, quiet operation, and long-term use.
Conclusion
Choosing the right indoor unit is about more than heating and cooling—it is about finding a solution that fits the space, layout, and daily needs of the business.
With 360° airflow, quiet operation as low as 29 dB, a built-in condensate pump, and Ultra Heat performance down to -40°F, the TOSOT Aoraki Ceiling Cassette is designed to bring flexible, year-round comfort to a wide range of light-commercial spaces. With 9K, 12K, 18K, and 24K BTU options, it offers contractors and building owners more flexibility when planning a ductless HVAC solution.
For spaces where wall space, aesthetics, airflow distribution, and extreme-weather performance all matter, the Aoraki Ceiling Cassette mini split offers a practical way to design comfort around the space—not the other way around.
Frequently Asked Questions
Q: What is the required ceiling clearance for installing the Aoraki Ceiling Cassette?
A: For 9,000–18,000 BTU models, a minimum ceiling clearance of 11½ inches is required. The 24,000 BTU model requires 10½ inches of clearance. This provides sufficient space for piping, drainage, and panel installation.
Q: What are the energy efficiency ratings and coverage areas for each model?
A:
- 9,000 BTU: 24 SEER2 / 9.2 HSPF2 | Up to 194 sq. ft.
- 12,000 BTU: 23 SEER2 / 9.0 HSPF2 | Up to 258 sq. ft.
- 18,000 BTU: 21 SEER2 / 9.0 HSPF2 | Up to 366 sq. ft.
- 24,000 BTU: 22.5 SEER2 / 9.0 HSPF2 | Up to 452 sq. ft.
Actual coverage can vary depending on factors such as insulation, ceiling height, climate, windows, occupancy, and heat-generating equipment. A professional load calculation is recommended for proper sizing.
Q: Can I install the Aoraki Ceiling Cassette myself?
A: This is not a DIY system. We strongly recommend installation by a licensed HVAC professional to ensure proper refrigerant connections, electrical work, drainage, system setup, efficiency, and safe operation.
Q: What accessories are included with the Aoraki Ceiling Cassette?
A: The package includes a 16.4 ft line set and most essential installation accessories. Please note that power cables and electrical wiring are not included and must be sourced separately.
Q: How do I clean and maintain the Aoraki Ceiling Cassette?
A: We recommend routine maintenance at least once each season. Clean the air filters, inspect the evaporator and condenser coils, and remove debris from around the outdoor unit. Regular maintenance helps maintain airflow, efficiency, and reliable operation.
