Danfoss SM120-3VI Compressor

The Danfoss SM120-3VI (also known as the SM120S3VC) is a heavy-duty 10-ton scroll compressor engineered specifically for high-suction commercial air conditioning and chiller processes. This 3-phase, 3500 RPM motor is designed for 208-230V configurations at 60Hz and is optimized for R22 refrigerant applications. Built with a 1 3/8-inch suction and 7/8-inch discharge brazed connection, this unit facilitates a secure, leak-resistant installation for technicians servicing large-scale HVAC systems. It features a displacement of 10.16 in³/rev and utilizes an initial 110 fl.oz. (3.25L) charge of 160P mineral oil to maintain internal lubrication and heat dissipation. The Danfoss SM120S3VC serves as a direct drop-in replacement for part number 1098232, ensuring compatibility with existing mounting footprints. With a maximum continuous current (MCC) of 48A and internal motor protection, it provides the thermal stability required for demanding industrial cycles.

• Direct Compatibility: Functionally replaces part 1098232, reducing downtime during emergency retrofits.
• Superior Liquid Handling: Advanced scroll design manages moderate liquid slugging more effectively than traditional reciprocating units.
• High Thermal Efficiency: Optimized for low-GWP transitions where R22 mineral oil systems remain the primary infrastructure.
• Internal Overload Protection: Built-in line break protects the motor windings against phase loss and excessive current draw.
• Brazed Fittings: Standard ODF connections ensure high-pressure integrity in 30.2 bar (high side) environments.

Is this compressor compatible with POE oil for R407C conversion?
This specific model is charged with 160P mineral oil for R22. If converting to R407C, the mineral oil must be thoroughly flushed and replaced with a compatible POE lubricant per Danfoss manufacturer guidelines.

What is the proper wiring configuration for the 3-phase motor?
The motor is rated for 200-230V/3/60Hz. It is critical to verify phase rotation before startup to prevent the scroll sets from running in reverse, which can cause immediate mechanical failure.

Does it come with the necessary mounting hardware?
Yes, this unit typically includes the mounting grommets and sleeves required to isolate vibration from the equipment chassis.
