Danfoss SM090-3VI Scroll Compressor

The Danfoss SM090-3VI Scroll Compressor is a high-efficiency R22 scroll compressor engineered specifically for medium and high-temperature air conditioning applications. Operating on a 200-230V 3-phase power supply at 60Hz, this 7.5 ton compressor delivers a nominal capacity of 90,000 BTU/hr. Designed for heavy-duty commercial use, the SM090-3VI features a braze-type connection with a 1-1/8" suction line and a 7/8" discharge line. This Danfoss Danfoss Synegy model utilizes mineral oil and is built to handle high load demands while maintaining low sound levels and high energy efficiency ratios. Its internal motor protection and robust mechanical design ensure reliable performance in demanding rooftop units and chillers. When replacing an aging commercial HVAC compressor, ensuring correct voltage and refrigerant compatibility is critical for system longevity and oil return stabilization.

• Optimized Performance: Specifically tuned for R22 refrigerant systems to maintain precise suction and discharge pressure.
• High Displacement: Features a displacement of 7.35 in3/rev, providing consistent mass flow for large tonnage applications.
• Simplified Installation: Standard 3-leg mounting pattern and braze-on stubs streamline the change-out process.
• Thermal Management: Engineered with internal pressure relief valves to prevent damage during extreme operating conditions.

What is the proper oil type for the SM090-3VI?
This model is factory-charged with mineral oil (160P), which is compatible with R22 systems. Always verify oil levels after piping to ensure proper lubrication of the scroll sets.

Can this compressor be used with a VFD?
The SM090-3VI is designed for constant speed operation. For variable speed applications, check for specific Danfoss inverter-rated models to avoid motor overheating.

Is this a direct replacement for other 7.5 ton units?
While it fits most 7.5 ton footprints, always confirm the suction and discharge orientations and electrical terminal box location to ensure matching pipework and wiring.
