O General 3.0 Ton (36,000 BTU) – ARGH36CMTA-U / AOGH36CBTA-U
Product Overview: The ARGH36CMTA-U is a 3 Ton (nominal 36,000 BTU/h) ducted inverter split, the largest capacity available on single-phase power in this series. It’s ideal for large open areas, villas with multiple rooms fed by one unit, or small commercial spaces (~50–60 m²). With 9.50 kW cooling capacity at T1, this model provides substantial cooling output while still benefiting from the inverter efficiency and slim design of the 18–30 models (it shares the 1.4 m width chassis with the 30k unit). The outdoor unit (AOGH36CBTA-U) is the most powerful one that can run on 240V, featuring robust components to ensure stability at high loads. Importantly, this 36k BTU unit is tropicalized to handle up to 52 °C ambient without derating thanks to enhanced compressor cooling and a larger condenser – at 46 °C (T3) it still delivers about 8.53 kW (29,100 BTU) of cooling. This makes it a go-to choice for top-floor halls or sun-exposed areas. Despite its power, the indoor noise remains comfortable (41 dB on high, which is quiet for 3 Ton), and installation is similar to the 30k unit.
Key Features:
- High cooling capacity with flexible modulation – it can drop as low as ~2.50 kW output when the load is light, preventing frequent cycling.
- The EER is a solid 12.00 BTU/W at T1 (the highest in the lineup), indicating excellent efficiency for a 3 Ton system.
- This model comes standard with a slightly higher static pressure capability by design (the factory default might be ~50 Pa for optimal airflow, adjustable to 150 Pa) to push air through extensive duct networks.
- The indoor unit’s twin fan design (if applicable) or single larger fan ensures airflow up to ~1,600+ CFM on high, enough for multiple diffusers.
- All standard features apply: quiet DC fan motor, auto-restart, washable filter, optional Wi-Fi control, etc. Many small businesses (restaurants, clinics) choose the ARGH36 for its reliability and because it can run on available single-phase supply, avoiding the need for costly electrical upgrades.

Usage Note: The 36,000 BTU model is often at the cusp of requiring more infrastructure (as it pushes the limits of single-phase). Ensure the electrical circuit is robust and has appropriate breaker (approx 16–20A) and wiring gauge for ~12 A continuous draw. This unit is capable of cooling multiple rooms: e.g., a small 2-bedroom apartment (with ducts into each room) or a large open floor. If using the unit at high static pressure, consider the impact on noise and have your installer tweak the fan settings accordingly. The outdoor unit for 3 Ton is larger and heavier; typically it’s floor-mounted or rooftop (not recommended for wall brackets at ~49 kg). Ensure clearances around the outdoor unit per the installation manual for proper airflow. Regular coil cleaning (especially for the outdoor unit’s large condenser) will keep performance optimal in dusty environments.
