SAC2M-U18SKWA/I

Year-Round Comfort

Engineered as a highly efficient air-to-air heat pump, this unit is certified for stable heating operation at outdoor temperatures down to -20°C...-22°C and cooling up to +43°C. Thanks to an intelligent refrigerant distribution system, the outdoor unit smoothly regulates capacity for each room individually, maintaining target parameters with an accuracy of up to 0.5°C and eliminating sudden startup loads on the local power grid.

Technical Advantages & Features

• High Energy Efficiency Class (A++ / A+++): Full DC inverter control ensures outstanding seasonal efficiency, delivering a SEER of up to 6.1 (for cooling) and a SCOP of up to 4.0 (for heating).

• Reliable Japanese Brand Compressor: The unit is equipped with a highly efficient GMCC (Toshiba) or Highly (Hitachi) compressor with enhanced rotor balancing, guaranteeing an extended operational lifespan.

• Eco-Friendly R32 Refrigerant: The system is fully optimized for next-generation, ozone-safe R32 refrigerant, which increases overall capacity by 10% and significantly lowers energy consumption.

• Winter Kit: Factory-installed intelligent crankcase and basepan heaters prevent condensate freezing and protect crucial mechanical components from damage during sub-zero startups.

Installation & Operation Insights

• From our engineering teams' experience: The SAC2M-U18SKWA/I outdoor unit weighs approximately 34-38 kg and features a relatively compact footprint. It is mounted exclusively on reinforced metal brackets with specialized rubber vibration dampers to completely isolate micro-oscillations and ensure absolute quietness inside the home.

• When designing the refrigerant lines, we carefully calculate the total pipe length and elevation drops to both rooms, utilizing high-quality, thick-walled copper piping to guarantee reliable operation under the high working pressure of R32 refrigerant.

Comparison with Other SENSEI Solutions

The SAC2M-U18SKWA/I model holds a massive advantage over installing two separate split systems, as it allows you to air-condition two rooms using only one outdoor unit. 

Best Suited For:

• Owners of 2-room apartments and small cottages who face strict developer restrictions regarding exterior wall aesthetics but want full independent climate control in two rooms.

• Properties with strict power consumption limits, where the simultaneous startup of two conventional space heaters or ACs would trip the circuit breakers.

Might Not Be Suited For:

• If you plan to air-condition more than two rooms, or if the total combined area exceeds 50-55 m², the capacity of this 5.2 kW unit will be insufficient; it is better to opt for a higher-capacity multi-split model.
