SAC5M-U42SKWA/I

Year-Round Comfort

A top-capacity multi-split outdoor unit designed for stable heating in winter conditions down to -20°C and reliable cooling up to +43°C. Smart electronic expansion valves (EEVs) dynamically balance refrigerant across 5 ports, maintaining precise room temperatures within ±0.5°C without uncomfortable fluctuations.

Technical Advantages & Features

• Energy Efficiency (A++ / A+): Advanced system delivering 12.3 kW cooling and 12.3 kW heating capacity with high seasonal efficiency and low energy consumption.

• Twin-Rotary Compressor: Heavy-duty compressor with enhanced rotor balancing and dual-layer sound insulation to keep outdoor sound pressure levels down to 61 dB.

• Eco-Friendly R32: Optimized for next-generation R32 refrigerant, improving heat transfer efficiency by 10% with a lower charge volume.

• Smart Defrosting: Intelligent auto-defrosting monitors coil temperature to remove ice buildup only when needed during cold winter conditions.

Comparison with SAC4M-36SKWA/I

• 5-Port Capacity: Connects up to 5 indoor units simultaneously (vs 4 ports on the 36 model).

• Maximum Output: 12.3 kW capacity easily covers extensive total areas (up to 120–130 m²).

• High Reserve: Engineered to support simultaneous peak load across 5 separate zones without bottlenecking performance.

Best Suited For:

Spacious 5-room apartments, multi-level private houses, or large commercial offices (up to 130 m²) requiring maximum multi-zone coverage, quiet operation, and effective winter heating down to -20°C.

Might Not Be Suited For:

Smaller setups under 100 m² with up to 4 rooms, where the SAC4M-36SKWA/I is a more compact and balanced choice.
