Energy Efficiency of O General's ARGH CMTA-U Series
In addition, the use of eco-friendly R32 refrigerant means lower environmental impact and improved efficiency, aligning with modern green building standards. Each model in this lineup is built to instill confidence, from premium materials and rigorous certifications to comprehensive warranty coverage (with extended compressor warranties available. The units carry high EER ratings for both standard (T1) and high-temperature (T3) conditions, indicating significant energy savings.



Key Features & Benefits
High Energy Efficiency (Inverter + R32)
All models are equipped with DC inverter compressors and motors, achieving exceptional EER values up to 12.0 (T1 condition). Even under the harsh T3 condition (46 °C outdoor), the new series outperforms previous fixed-speed models by 8–10% higher EER. This means lower electricity bills and adherence to the UAE’s energy efficiency standards. The R32 refrigerant further boosts cooling performance per unit of power while reducing GWP (global warming potential)
Tropical Cooling Performance
Purpose-built for the Middle East, these ducted split ACs provide reliable cooling in ambient temperatures up to 55 °C. The “T3” tropical rating assures that even at extreme heat, the unit maintains comfort for example, the 2 Ton model still delivers ~19,400 BTU/h at 46 °C outdoor. Robust components (e.g. large heat exchangers and optimized compressors) ensure over 80% cooling capacity at 49 °C and stable operation without tripping. Additionally, a built-in compressor pre-heating control protects the system during cooler nights, ensuring a smooth restart on hot days
Slim & Compact Design
The indoor duct units feature an ultra-slim height (only 240 mm for 1.5 to 3 Ton models), fitting into narrow false ceilings and tight spaces. Even the largest 5-ton model has a streamlined profile, minimizing the ceiling space required. The lightweight construction makes handling and installation easier for instance, the 1.5-ton indoor unit weighs just ~30 kg. The outdoor units are also compact and lighter than previous generations, allowing flexible placement on rooftops or balconies. (For example, the 2 Ton outdoor is only 799 mm wide and 31 kg in weight)
High Static Pressure with Easy Adjustment
Designed for ducted installations, these units support a wide range of external static pressures (30 to 150 Pa), suitable for both short and long duct runs. You can adjust the fan static pressure settings directly from the wired remote controller, optimizing airflow for each project’s duct layout. This ensures every room gets adequate cooling, whether it’s a small bedroom or a large hall, without overworking the fan. Multiple fan speed modes (High/Med/Low/Quiet) allow further tuning of airflow and comfort.
Quiet Operation
Enjoy cool comfort without the noise. O General’s ducted units run with remarkably low sound levels thanks to insulated construction and variable-speed fans. In Quiet mode, indoor sound pressure can be as low as 24 dB(A) practically whisper-quiet, ideal for bedrooms at night. Even on high fan speed, the noise stays modest (around 37 - 44 dB for most models, akin to a quiet office. The outdoor units are also engineered for low noise, keeping neighbors happy and meeting strict community noise regulations (all models’ indoor/outdoor sound levels are below 70 dB(A) maximum).
Easy Maintenance & Installation
Simplified service access and installation features save time for contractors and facility managers. Large service panels on both sides of the indoor unit provide convenient access to internal components even in cramped ceiling spaces. The heat exchanger is designed for easy cleaning, and the air filters slide out easily for replacement or cleaning. (Long-life filters) They are available as an optional accessory for extended maintenance cycles. The unit supports two-directional drain piping (left or right) for flexible condensate drain installation, and an integrated drain pump (with auto shut-off) ensures efficient removal of condensate water, preventing leaks even in high-humidity conditions. All refrigeration connections are via standard flare fittings for a quick, secure hookup.
Smart Controls & Connectivity
O General offers multiple control options to suit different users. Each unit can be paired with an optional wired wall-mounted controller for precise settings of temperature, fan speed, and scheduling. Additionally, these models are Wi-Fi ready; simply plug in the optional WLAN adapter to enable smartphone control via the Fujitsu General “AIRSTAGE” mobile app. This allows homeowners and facility managers to monitor and adjust cooling remotely, set timers, and even integrate with smart home systems. The ACs also feature an Auto-Restart function so they resume with previous settings after a power outage, and an Economy mode to conserve energy during mild conditions. For integration into building management systems, a dry contact interface is available for on/off control or error status monitoring (useful in commercial installations).
Durability & Trust
Built with high-quality galvanized steel cabinets and anti-corrosion coated heat exchangers, these ducted units are made to withstand the dusty, hot, and humid conditions of the Gulf. Key electrical components are tropicalized and protected against voltage fluctuations (units operate within a wide voltage range without performance loss, Safety protections like high-temp cut-off, low-temp protection, overcurrent protection, and high-pressure safety are all incorporated to safeguard the system). O General backs this series with a comprehensive warranty (typically 1 year full unit, 5 years on compressor) and has an extensive service network in the UAE. With international certifications and compliance (ISO 9001 manufacturing, ISO 14001 environmental management, and tested per IEC/ISO standards for performance and safety), you can trust these units for long-term cooling performance.
Environmentally Friendly
By choosing this O General R32 inverter series, you are making an eco-conscious decision. R32 refrigerant has zero ozone depletion potential and about 1/3 the global warming potential of older R410A refrigerant, aligning with global and UAE environmental regulations. Moreover, the high efficiency means reduced carbon footprint over the AC’s lifetime. O General also utilizes lead-free solder and recyclable materials in manufacturing these units, supporting sustainability goals. In summary, O General’s ducted split air conditioners provide a perfect blend of energy-saving operation, powerful tropical cooling, quiet and slim design, and smart control all backed by the brand’s renowned reliability. Below is a breakdown of each model in the series, including its features, specifications, and applicable use cases, so you can select the ideal unit for your needs.
