Danfoss 120U1726 Scroll Compressor

The Danfoss 120U1726 Scroll Compressor, specifically the HRP060T4LP6 model, is a high-performance solution for residential and light commercial air conditioning systems. Engineered for high-temperature applications, this hermetic scroll compressor is optimized for R407C and R22 refrigerants, delivering a nominal capacity of 60,000 Btu/h at 60 Hz. Designed for 3-phase power (380-415V/50Hz and 460V/60Hz), it features internal motor protection and a compact footprint that simplifies field installation. This unit is the direct technical replacement for discontinued or legacy models including the 120U1736, 120U1711, 120U1721, and HRM060T4LP6. Utilizing PVE oil (Polyvinyl Ether), it ensures superior moisture tolerance and lubrication stability in demanding HVACR environments. The 7/8" ODF suction and 1/2" ODF discharge sweat connections provide a robust, leak-free interface, making it a reliable choice for contractors looking to restore system efficiency with minimal redesign.

Key Benefits

• Optimized Efficiency: Precision-matched for ARI conditions at 45/130°F, ensuring peak performance in residential scroll compressor applications.
• Dual Refrigerant Compatibility: Designed for seamless operation with R407C and R22, facilitating easier retrofits and service calls.
• Enhanced Durability: Features internal overload protection and high-torque motor characteristics to handle fluctuating thermal loads.
• Simplified Service: Equipped with spade terminals and standard ODF sweat connections for fast, secure electrical and piping hookups.
• Broad Interchangeability: Serves as a Danfoss 120U1726 replacement for multiple older H-series models, reducing inventory complexity.

Common Questions

Is the 120U1726 compatible with mineral oil systems?
This model is charged with 1.57L of PVE oil. When retrofitting an older R22 system that used mineral oil, PVE is preferred over POE because it does not require the same level of moisture-critical handling while providing excellent miscibility with HFCs.

Does this compressor include a crankcase heater?
The standard 121L1726/120U1726 package typically excludes the crankcase heater. For low-ambient operation, a wrap-around or surface sump heater should be sourced separately to prevent liquid migration during off-cycles.

What are the electrical requirements for the HRP060T4LP6?
It is a 3-phase unit requiring 460V at 60Hz. It has a Locked Rotor Amperage (LRA) of 70A and a Maximum Continuous Current (MCC) of 15A. Always verify your branch circuit protection and contactor sizing before installation.
