Danfoss SM185-4CAI Scroll Compressor

Professional-grade and high-capacity, the Danfoss SM185-4CAI is a high-performance HVAC scroll compressor designed specifically for large-scale commercial and industrial air conditioning applications. Engineered for use with R22 refrigerant, this 460V 3Ph 185,400 BTU unit provides reliable, heavy-duty cooling consistent with the Performer series standards. The advanced internal design features a gas intake architecture that offers superior resistance to liquid slugging, a common cause of premature failure in field operations. Additionally, improved part isolation significantly reduces acoustic vibration levels, making it ideal for noise-sensitive installations. With a swept volume of 249.9 cm³ per revolution, the 15-ton commercial scroll compressor ensures maximum volumetric efficiency and consistent performance across various load conditions. The SM185-4CAI utilizes mineral oil (160P) for lubrication and features 1-5/8 inch ODF suction and 1-1/8 inch ODF discharge brazed connections for simplified integration into existing system manifolds.

• Enhanced Durability: Robust internal components and a reinforced internal pressure relief (IPR) valve design provide long-term operational stability.
• Operational Efficiency: Optimized for high-BTU output with low energy consumption, reducing overall facility overhead.
• Reduced Maintenance: Low vibration and noise profiles minimize mechanical stress on connecting pipework and mounting hardware.
• Direct Compatibility: Exact technical match for heavy-duty 460V three-phase systems requiring dependable R22 performance.

What are the specific line sizes for the SM185-4CAI?
This model features brazed (ODF) connections with a 1-5/8" suction line and a 1-1/8" discharge line to accommodate high-volume refrigerant flow.

Is this compressor compatible with R407C or R410A?
The SM185-4CAI is factory-charged for R22 and R417A applications utilizing mineral oil; it is not recommended for HFC/POE systems without thorough conversion procedures.

What electrical protection is required for this 3-phase unit?
Standard installations require appropriate phase monitors and overload protection to safeguard the 460V motor against phase loss or voltage imbalance.
