Toshiba Ducted Systems – Hidden Power

The Toshiba Ducted Series represents the perfect fusion of performance, efficiency, and architectural discretion. Designed for commercial environments such as offices, hotels, and retail stores, these systems deliver powerful yet silent comfort while remaining completely hidden within ceilings or service voids.

Design and Discreet Operation

Toshiba ducted systems are installed above suspended ceilings, with only discreet air grilles visible.
The low-profile indoor units — as slim as 245 mm in height — make them ideal for buildings where aesthetics matter.
Airflow is distributed evenly through ducts and diffusers, providing smooth and draught-free comfort.

Performance and Efficiency

The latest Inverter Ducted Units (MMU-AP series) achieve impressive seasonal efficiencies:

• SEER: up to 8.3

• SCOP: up to 4.9

• Energy class: A++
  The systems use DC Twin Rotary Compressors and R32 refrigerant, reducing CO₂ equivalent emissions by up to 68 % compared with older R410A systems.
  Heating operation is reliable down to –20 °C, suitable for year-round comfort.

Airflow Control

Airflow pressure can be adjusted between 30–150 Pa, enabling flexible duct design for both short and long runs.
An integrated fan-speed control maintains constant airflow volume regardless of duct resistance, ensuring balanced air distribution across multiple zones.

Noise Reduction

Noise levels are remarkably low — indoor units operate from 23 dB(A) in quiet mode.
Outdoor sound levels are around 46–50 dB(A), meeting urban and office building standards.
This makes Toshiba ducted systems ideal for open-plan offices, meeting rooms, and luxury retail environments.

Control and Integration

Toshiba offers multiple control options:

• Wired Touchscreen Controllers (RB-N104S-G)

• Wi-Fi control via Toshiba Home AC App

• Centralised BMS control (BACnet, Modbus)

Integration with lighting and building management systems ensures full automation and monitoring.

Installation Flexibility

The lightweight indoor unit (from 20–29 kg) simplifies ceiling installation.
Drain pump lift height up to 850 mm provides flexibility in condensate routing.
Piping lengths reach 75 m total, with 30 m height difference, allowing rooftop or basement condenser placement.

Example Use Case

A boutique hotel in Manchester replaced outdated split systems with Toshiba ducted inverters, achieving 32 % lower energy consumption and uniform comfort across all 18 guest rooms.

Conclusion

Toshiba ducted systems deliver hidden yet powerful performance.
Combining compact design, whisper-quiet operation, and intelligent control, they offer architects and facility managers a flexible HVAC solution that preserves interior aesthetics while ensuring year-round efficiency.
