Danfoss SM125-4CAI Scroll Compressor

The Danfoss SM125-4CAI is a high-capacity scroll compressor engineered for demanding commercial air conditioning and refrigeration applications. Operating on 460V 3-phase power, this unit delivers a nominal capacity of approximately 126,400 BTU/hr (BTUH), making it a reliable choice for large-scale systems utilizing R22 refrigerant. Designed with a standard 1-3/8" suction and 7/8" discharge ODF brazed connection, the SM125S4CC model ensures a secure, leak-resistant fit in legacy setups. As a veteran technician, you know the importance of internal motor protection and high-efficiency scroll geometry for long-term reliability in the field. This Danfoss Performer scroll is specifically optimized for low-vibration and quiet operation, essential for rooftop and split-system maintenance. Whether you are performing a drop-in replacement or a system overhaul, this 460V HVAC compressor provides the high-torque performance required for R22 HVAC systems without the need for extensive modification.

• Optimized Performance: Specifically engineered for R22 and compatible with mineral oil (OMR) systems to maintain system integrity.
• Durable Construction: Features a high-tolerance scroll design that minimizes internal friction and maximizes compression efficiency.
• Seamless Integration: Standard ODF brazed connections (1-3/8" x 7/8") allow for straightforward installation in existing commercial 460V 3-phase circuits.
• Operational Reliability: Built for continuous duty in air conditioning applications with a high nominal motor speed of 3500 RPM.

Is the SM125-4CAI compatible with R417A?
Yes, while primarily designed for R22 refrigerant, this model is frequently used with R417A in retrofit scenarios, provided the lubricant and system parameters are correctly managed.

What is the connection type for this model?
This unit features ODF brazed (sweat) connections, specifically a 1-3/8" suction line and a 7/8" discharge line, ensuring a robust seal for high-pressure R22 applications.

Does this compressor include a sight glass?
The SM125S4CC typically includes a threaded sight glass port for easy oil level monitoring, a critical feature for large multi-circuit commercial systems.
