When designing comfort systems for large commercial spaces, specifiers often run into the same challenge, how do you deliver high-capacity heating and cooling when the building has limited ceiling depth, no accessible void, or an open structure that simply isn’t compatible with ceiling cassettes or ducted systems? Toshiba’s RAV Floor Standing Digital Inverter Series 1 answers this problem with a combination of power, flexibility and reliability that fits seamlessly into modern commercial environments. The Series 1 range brings together consistent cabinet dimensions, strong airflow and air throw performance and advanced R32-based inverter heat pump technology, making it one of the most versatile floor-standing solutions available on the market.
What sets these units apart is their ability to deliver controlled, large-volume airflow at comfortable sound levels, while occupying a relatively compact footprint. Whether they’re placed against a wall, positioned within a retail layout, or installed in multi-room complexes such as schools and healthcare settings, the units ensure reliable all-year-round performance. The indoor range includes four models, 5.0 kW, 6.7 kW, 9.5 kW and 12.1 kW cooling capacities, each sharing the same cabinet size and overall design. For engineers and installers, this creates a predictable and uniform installation experience, no matter which capacity is selected.
To make system design even easier, each unit pairs directly with Toshiba’s Digital Inverter outdoor units, available in both single-phase (220–240V~50Hz) and three-phase (380–415V~50Hz) variants. This means the same indoor unit can be installed across multiple voltage types, from older retail units still running single-phase supplies to newer commercial facilities equipped with three-phase distribution. The compatibility with Digital Inverter and Super Digital Inverter outdoor units gives the range a scale of flexibility rarely seen in floor-standing systems.
Toshiba RAV Floor Standing Digital Inverter – Indoor Unit Comparison:
| Indoor Model | Cooling Capacity | Heating Capacity | UK Cooling | UK Heating | Airflow (H–M–L) | Sound Pressure (H–M–L) | Dimensions (HxWxD) | Weight | Pipe Size (Gas–Liquid) |
|---|---|---|---|---|---|---|---|---|---|
| RAV-HM561FT-E | 5.0 kW | 5.3 kW | 4.72 kW | 4.27 kW | 172 / 153 / 130 l/s | 43 / 39 / 35 dB(A) | 1750 × 600 × 390 mm | 59–68 kg | 1/2" – 1/4" |
| RAV-HM801FT-E | 6.7 kW | 7.7 kW | 6.41 kW | 5.89 kW | 194 / 167 / 144 l/s | 46 / 42 / 38 dB(A) | 1750 × 600 × 390 mm | 59–68 kg | 1/2" – 3/8" |
| RAV-HM1101FT-E | 9.5 kW | 11.2 kW | 9.00 kW | 8.01 kW | 461 / 394 / 325 l/s | 51 / 46 / 41 dB(A) | 1750 × 600 × 390 mm | 59–68 kg | 5/8" – 3/8" |
| RAV-HM1401FT-E | 12.1 kW | 13.0 kW | 12.03 kW | 10.68 kW | ~500 l/s class | ~52 / ~46 dB(A) | 1750 × 600 × 390 mm | 59–68 kg | 5/8" – 3/8" |
Each unit features automatic louvre control, allowing consistent temperature distribution regardless of where the unit is placed. The inclusion of five fan-speed settings gives users control ranging from whisper-quiet operation to full-power airflow, making the systems adaptable to meeting rooms, open-plan spaces and high-traffic commercial areas. The design places a strong focus on airflow stability and directional control, which is particularly important in long or deep rooms where thermal drift is often an issue.
One of the most useful aspects, consistently present in your technical notes, is the built-in R32 refrigerant leak detection system, complete with a stirring-fan operation to prevent stagnation in the event of a leak. This is increasingly important in environments such as classrooms, hospices, surgeries and multi-occupancy spaces where safety and compliance form a critical part of system design. The units also include the RBC-AMS55-ES wired controller as standard, offering a fully integrated control interface without requiring additional accessory purchases. This enhances usability, reduces installation time and gives the end user a reliable point of control directly from the cabinet.
The replacement-technology pipe capability is another advantage worth highlighting. The ability to re-use existing R410A, R22 or R407C pipework in suitable installations makes these units ideal for refurbishment projects, particularly in older commercial buildings where pipe runs are embedded in structure or access is restricted. With rising demand for sustainable upgrades and lower-emission refrigerants like R32, this compatibility offers a valuable bridge between legacy installations and modern energy-efficient systems.
The Series 1 outdoor Digital Inverter units complement the indoor range perfectly, scaling from 5 kW to 13 kW in single-phase and three-phase options. This makes the system suitable for both small commercial rooms and significantly larger installations requiring capacities beyond. Overall, the Toshiba RAV Floor Standing Digital Inverter Series 1 is a robust, flexible and technically refined solution for the modern commercial HVAC landscape.
Its design solves practical installation challenges, its performance supports demanding environments, and its compatibility across electrical types and legacy pipework makes it as versatile as it is powerful. With a combination of strong airflow, dependable capacities and intelligent control features, it stands out as a dependable choice for engineers and decision-makers looking for a future-proofed comfort system.
