Bonaire 12.5kW Ducted System Overview
The Bonaire 12.5kW ducted system provides central reverse cycle heating and cooling through a concealed indoor unit, matching outdoor unit and professionally designed duct network. It combines the CTG125S1AI indoor unit with the CTG125S1AE outdoor unit as one complete matched system.
With 12.5kW rated cooling capacity and 15.0kW rated heating capacity, this system is designed for appropriately sized whole-home applications and larger residential areas. Conditioned air is distributed through ducts and outlets positioned throughout selected areas of the property.
The indoor fan-coil unit is normally concealed inside a suitable roof or ceiling space, helping preserve a clean interior appearance. When combined with a professionally designed zoning system, occupants may be able to direct conditioned air to selected rooms or areas.
The Bonaire Optima ducted range combines inverter technology, a high-efficiency DC motor, up to 200Pa external static pressure, R32 refrigerant and compatibility with optional Wi-Fi and third-party zoning controllers. The system also includes eco mode, DRED compatibility and quiet night-mode operation.

Why Choose the Bonaire 12.5kW Ducted System?
The Bonaire 12.5kW ducted system is suitable for homeowners wanting discreet climate control across several rooms without installing visible wall-mounted indoor units throughout the property.
The concealed indoor unit connects to a network of insulated ducts. Supply-air outlets distribute heated or cooled air, while a return-air grille draws indoor air back to the system. The duct layout and outlet positions should be designed according to the building’s heat load and airflow requirements.
Inverter technology allows the compressor to adjust its output as demand changes. The system has a published cooling operating range of approximately 4.0kW to 13.5kW and a heating range of approximately 4.3kW to 15.8kW.
This variable operation can help maintain steadier conditions as outdoor temperatures, active zones and household occupancy change. Actual energy consumption depends on the installation, property, selected temperature, zone usage and operating conditions.
Key Features
Whole-Home Reverse Cycle Operation
The system can provide central heating and cooling across multiple rooms through a professionally designed duct and outlet network.
High-Static Airflow Performance
The Sirocco turbine fan design supports adjustable external static pressure up to 200Pa. This helps the indoor unit move air through suitable ductwork and multiple supply outlets.
DC Motor and Inverter Design
A high-efficiency DC fan motor and inverter compressor allow the system to adjust its operation based on changing heating and cooling demand.
Optional Wi-Fi Integration
A compatible optional Wi-Fi controller can provide remote-control functionality. Wi-Fi equipment should be confirmed as a separate inclusion in the quotation.
Third-Party Zoning Compatibility
The system can integrate with suitable third-party zoning controllers. Zone motors, sensors, dampers and smart-control equipment may be separately supplied.
Modular Indoor Design
The indoor unit’s modular configuration supports installation flexibility in suitable roof spaces. Available access, roof clearance and service requirements must be inspected before installation.
R32 Refrigerant
The system uses R32 refrigerant. All installation, commissioning and refrigerant work must be completed by an appropriately licensed air conditioning professional.
Eco Mode and DRED Compatibility
Eco mode supports more economical operation, while DRED compatibility allows the system to participate in suitable demand-response arrangements when correctly connected.
Quiet Night Mode
Quiet night mode can reduce outdoor operating noise when quieter operation is preferred. Actual noise levels depend on operating conditions and installation.
Industry-Leading 7-Year Warranty
Bonaire promotes a seven-year parts and labour warranty for eligible ducted reverse cycle systems. Warranty eligibility may depend on professional installation, registration, proof of purchase, servicing requirements and compliance with the manufacturer’s current warranty conditions. Customers should retain all purchase, installation and maintenance records.
Ideal Applications
- Medium whole-home applications
- Single-storey houses with suitable roof space
- Multiple bedrooms and larger living areas
- New residential construction
- Renovation and replacement projects
- Homes requiring multiple air conditioning zones
- Properties where concealed indoor equipment is preferred
The Bonaire 12.5kW ducted system must be selected using a proper heat-load assessment. Building size, insulation, windows, ceiling height, room orientation, occupancy and duct losses can significantly change the capacity required.
