III. Detailed Explanation

Feature – Technical Characteristics

The SZ Series inherits the core technological DNA of Danfoss S-Series scroll compressors: an intermediate thermal shield design for high energy efficiency and low noise levels; an internal check valve to prevent refrigerant leakage from the high-pressure side; a "contact-free and wear-free" scroll design to reduce friction; lead-free eco-friendly bearings; and oil sight glasses and oil equalizers for easy parallel unit setup. Factory-charged with POE ester oil (160SZ), which is key to adapting to HFC refrigerants, the SZ Series is compatible with various refrigerants such as R407C, R134a, R404A, and R507A.

Advantage – Technical Advantages

The multi-refrigerant compatibility of the SZ Series makes it an ideal choice for OEMs and contractors—a single compressor model can adapt to multiple refrigerant solutions, greatly simplifying inventory management and reducing refrigerant switching costs. Models SZ084–SZ110 achieve a COP of 3.15–3.17, delivering solid energy efficiency. Covering a complete power spectrum from 7 HP to 30 HP and available in both single and dual-unit parallel configurations, the SZ Series meets the needs of projects of all sizes. For markets undergoing an eco-friendly refrigerant transition, the SZ Series provides a one-stop compatible solution for transitioning from R22 to R407C/R134a.

Benefit – User Benefits

For OEMs: The SZ Series means one compressor fits multiple refrigerant solutions, reducing R&D costs and inventory complexity.
For Contractors: It means no need to change compressor brands or installation methods when transitioning from R22 to HFC systems, lowering technical risks and training costs.
For End-Users & Service Technicians: It means no worries about refrigerant compatibility during compressor replacement, drastically reducing downtime.

IV. Application Scenarios

Application Scenario	Recommended Models	HP Range	Why It Fits
Small Commercial AC	SZ084–SZ100	7–8	R407C/R134a compatible, COP 3.15+
Medium Commercial AC / Rooftop Units	SZ110–SZ125ac	9–10	Compact design, flexible installation
Large Commercial AC / Water Chillers	SZ148–SZ185	12–15	Full compatibility with R407C/R134a/R404A/R507A
Large Chillers / Industrial Cooling	SZ240–SZ380	20–30	Extra-large cooling capacity, multi-refrigerant adaptation

The SZ Series is widely used in commercial air conditioning, water chillers, rooftop units, precision air conditioning, industrial cooling, and more.
