Not every commercial space should have an HVAC unit in plain sight.
Restaurants may want clean walls and ceilings. Offices may need conditioned air delivered to several areas from one indoor unit. Retail stores, studios, and renovated commercial spaces may have layouts where a traditional wall-mounted or ceiling cassette system simply does not fit the design.
That is where the TOSOT Aoraki Light Commercial Concealed Ducted Mini Split AC comes in.
Available in 18,000 and 24,000 BTU capacities, this concealed ducted mini split system places the indoor unit out of sight while using ductwork and supply grilles to deliver conditioned air where it is needed.
But hiding the equipment is only part of the story.
With 0–200 Pa adjustable external static pressure, a built-in condensate pump, up to 82 ft of vertical separation, and an operating range from -40°F to 140°F, the Aoraki Concealed Ducted Series is designed for commercial spaces where airflow and installation flexibility matter just as much as appearance.
Hide the Equipment, Not the Comfort
A concealed ducted indoor unit is typically installed above a ceiling or inside another service space, leaving only the supply and return grilles visible inside the room.
This allows contractors, designers, and property owners to integrate the HVAC system more discreetly into the space instead of designing the interior around a visible indoor unit.
It is particularly useful for:
- Offices and meeting rooms
- Restaurants and cafés
- Retail stores
- Studios and salons
- Hotels and hospitality spaces
- Renovated commercial properties
- Spaces requiring multiple air outlets from one indoor unit
The result is a cleaner interior while retaining the efficiency and flexibility of a ducted heat-pump system.
Up to 200 Pa Static Pressure for More Flexible Duct Design
One of the key specifications of a concealed ducted HVAC system is external static pressure.
Static pressure affects how effectively the indoor fan can move air through ductwork, fittings, filters, and supply outlets. The Aoraki Concealed Ducted Series supports an adjustable external static pressure range from 0 to 200 Pa, giving installers more flexibility when working with different duct configurations.
Commercial projects may require multiple supply outlets, duct bends, transitions, or longer duct sections that add airflow resistance. Adjustable static pressure allows the system to be configured more closely to the actual duct design.
The 18K model also supports high/low static pressure switching, providing additional flexibility when matching fan performance to the installation.
For contractors, this makes the Aoraki a purpose-built concealed ducted solution for commercial HVAC applications where duct layout and airflow requirements need greater flexibility.
Built-In Condensate Pump
Concealed installations can also create drainage challenges.
During cooling operation, moisture removed from indoor air collects inside the unit and needs to be routed safely to a drain. Both Aoraki Concealed Ducted models include a built-in condensate pump, helping lift and move collected water when gravity drainage is not practical.
This can provide additional flexibility in suspended ceilings and other commercial spaces where the unit location does not align perfectly with the available drain.
Proper drain routing, service access, and regular maintenance are still important, but an integrated pump can simplify condensate management for many concealed ducted HVAC installations.
Built for Extreme Conditions From -40°F to 140°F
Commercial spaces may need heating and cooling throughout the year, even under demanding outdoor conditions.
The Aoraki Light Commercial platform is engineered around an operating range from -40°F to 140°F. The series also features intelligent defrost and forced defrost functions to help manage frost accumulation during low-temperature heating operation.
For spaces that may remain unattended for periods of time, an 8°C / 46°F freeze-protection mode can help maintain a minimum indoor temperature and reduce the risk of frozen pipes.
Together, these features support year-round temperature control for commercial applications in a wide range of climates.
Flexible Installation for Commercial Spaces
Both the 18K and 24K models support up to 82 ft of maximum vertical separation between the indoor and outdoor units, providing more flexibility when the outdoor unit needs to be installed at ground level, on a rooftop, or in a designated mechanical area away from occupied spaces.
For more demanding cold-weather applications, the 24K model also includes auxiliary electric heat, providing additional heating support when needed.
Backed by GREE HVAC Manufacturing Experience
The Aoraki Light Commercial Series uses GREE compressors, bringing GREE's HVAC manufacturing and engineering experience into the platform.
The system combines inverter operation, airflow control, low-voltage startup, intelligent defrost, wide operating temperatures, and commercial-duty installation features into a single concealed ducted solution.
Frequently Asked Questions
Q: Does this concealed duct unit support smart app control?
A: Yes! You can conveniently control the unit via the Gree+ App from your smartphone. A tethered wall-mounted controller (wired remote) is also included for easy access.
Q: How do I choose the right size concealed duct mini split for my space?
A: The right size depends on the space's dimensions, insulation, layout, climate, and heating and cooling needs. The Aoraki Concealed Ducted Series is available in 18,000 BTU and 24,000 BTU models. Proper sizing by a qualified HVAC professional is recommended.
Q: What is the static pressure range of the Aoraki Concealed Ducted Series?
A: The system supports 0–200 Pa adjustable external static pressure, providing greater flexibility for different duct layouts and airflow requirements. The 18K model also supports high/low static pressure switching.
Q: Can I install this system myself, or is professional installation required?
A: This is not a DIY system. Professional installation by a licensed HVAC technician is strongly recommended to ensure proper setup, performance, and safe operation.
Q: How efficient is the Aoraki Concealed Ducted Series?
A: The 18K model reaches up to 22.5 SEER2 / 9.0 HSPF2, while the 24K model reaches up to 19.5 SEER2 / 9.0 HSPF2.
