Danfoss SZ148T4VC Scroll Compressor | 12 HP
Product Description:
The Danfoss SZ148T4VC (the primary replacement for the SZ148-4VAI series) is a professional-grade 12 HP scroll compressor built to handle heavy cooling loads with ease. Specifically optimized for HFC refrigerants like R407C and R134a, this unit is a standard choice for medium-sized rooftop units, chillers, and large split systems in the UAE. Its advanced scroll set is designed for high volumetric efficiency and low energy consumption, while its robust internal construction provides excellent resistance to thermal stress. Even in the peak of the Middle Eastern summer, the SZ148T4VC maintains stable cooling capacity and low noise levels, ensuring high-quality indoor comfort and reliable industrial process cooling.
Key Features & Benefits:
- Optimized 12 HP Capacity: Perfectly sized for commercial AC systems requiring a balance of high power and compact footprint.
- Extreme Climate Tolerance: Engineered to operate efficiently at high condensing temperatures common in the UAE.
- Advanced Energy Management: High COP (Coefficient of Performance) helps facility managers reduce electricity costs.
- Quiet & Stable Operation: Precision scroll machining minimizes vibration, extending the life of the entire refrigeration circuit.
- Ready for HFCs: Factory-charged with premium POE oil for immediate compatibility with R407C, R134a, and R404A.
