Danfoss SM110-4VI Scroll Compressor

The Danfoss SM110-4VI Scroll Compressor (Model SM110S4VC) is an industrial-grade solution specifically engineered for R22 refrigerant air conditioning and high-temperature refrigeration systems. Operating on a 3-phase, 400-460V power supply at 50/60 Hz, this 9-ton hermetic unit delivers a nominal capacity of approximately 107,850 to 128,330 BTU/H depending on operating conditions. Designed with 1-3/8 inch ODF suction and 7/8 inch ODF discharge brazed connections, it ensures a leak-proof seal in demanding environments. This fixed-speed scroll compressor utilizes a displacement of 144.2 cm³ and is pre-charged with 160P mineral oil, maintaining high volumetric efficiency and thermal stability. The internal motor protection and IP54-rated terminal box provide robust reliability against electrical overloads and environmental moisture, making it a drop-in replacement for existing HVACR infrastructure where an SM110S4VC compressor is required.

• Optimized Performance: Specifically tuned for R22 systems, providing high-efficiency operation in high-temperature applications.
• Drop-in Compatibility: The SM110-4VI is technically identical to the SM110S4VC, ensuring seamless mechanical and electrical integration.
• Durable Construction: Features brazed ODF fittings and internal overload protection to withstand rigorous commercial duty cycles.
• Electrical Versatility: Dual-rated for 400V/50Hz and 460V/60Hz 3-phase power configurations to suit various regional standards.

Common Questions

Is the Danfoss SM110-4VI compatible with modern refrigerants?
This specific model is designed for R22 and R417A applications using mineral oil. Converting to HFCs like R407C would require a complete oil flush and replacement with PVE or POE lubricants; check manufacturer compatibility charts for conversion protocols.

What is the difference between the SM110-4VI and the SM110S4VC?
Technically, there is no difference. The SM110S4VC is the specific model number found on the nameplate, while SM110-4VI often refers to the ordering code for the same 400-460V 3-phase unit.

Can I use this compressor in low-temperature refrigeration?
No, this scroll compressor is optimized for air conditioning and high-temperature segments. Using it outside its design envelope, particularly in low-evaporating temperature ranges, can leading to insufficient motor cooling and premature failure.
