Danfoss SZ185-4CAI Compressor
The Danfoss SZ185-4CAI is a heavy-duty commercial scroll compressor engineered specifically for air conditioning and chiller applications. Operating on 460V 3-phase power, this fixed-speed hermetic unit delivers approximately 185,000 BTU/h of cooling capacity. It is exceptionally versatile, approved for use with R407C, R134a, R404A, and R507 refrigerants, and comes pre-charged with 160SZ POE oil. Built for high-ambient performance, the SZ185 features brazed connections (1-5/8" suction and 1-1/8" discharge) to ensure a leak-free seal in demanding environments. Technicians will appreciate the internal thermistor motor protection and the integrated oil sight glass, which simplify monitoring and maintenance. This Danfoss Performer SZ series compressor utilizes a "no contact-no wear" spiral design to reduce internal friction, resulting in high energy efficiency and significantly quieter operation compared to traditional reciprocating models.
Key Benefits:- Multi-Refrigerant Compatibility: Optimized for R407C, R134a, R404A, and R507, providing flexibility for various high-temperature system retrofits and new builds.
- Enhanced Durability: Features lead-free bearings and an internal non-return valve to prevent refrigerant migration during off-cycles.
- Superior Efficiency: The scroll compressor technology ensures continuous compression, reducing vibration and increasing the COP (Coefficient of Performance).
- Ease of Installation: Standard brazed ODF connections and a compact 317mm diameter facilitate a direct drop-in for many commercial liquid chillers and rooftop units.
- What is the maximum charge limit for this unit? The Danfoss SZ185-4CAI has a maximum refrigerant charge limit of 13.5 kg.
- Does this compressor include a crankcase heater? While it features an oil sight glass and leveling port, a crankcase heater is typically recommended for low-ambient starting and should be sourced separately based on system needs.
- What motor protection is integrated? This model uses an internal thermostat/thermistor to protect against overheating, though an external overload protector is often required for full circuit safety.
