Danfoss 120U1296 Scroll Compressor

The Danfoss 120U1296 is a professional-grade R410A scroll compressor engineered specifically for residential air conditioning and high-temperature HVACR applications. Known as a direct drop-in for Model HRH051U1LP6, this unit delivers a nominal capacity of 51,000 BTU/h at 60 Hz under ARI conditions. As a 208-230V single-phase compressor, it features internal motor protection and uses PVE oil to ensure consistent lubrication and chemical stability in high-pressure R410A systems. The hardware is built for hard-wired service with 7/8" ODF suction and 1/2" ODF discharge sweat connections, making it a reliable solution for technicians performing system-side replacements in 4.3-ton residential units.

• Optimized Performance: Designed for an operating envelope of 45/100 degrees Fahrenheit to maintain efficiency in high-ambient residential environments.
• Direct Compatibility: Exact technical match for Danfoss HRH051U1LP6, ensuring no modifications are needed for piping or electrical mounts.
• Thermal Safety: Equipped with internal motor protection to prevent overheating and winding failure during high-load periods.
• Advanced Lubrication: Formulated with PVE oil, which provides better moisture handling than traditional POE oils, reducing the risk of acid formation.
• Proven Scroll Technology: Utilizes scroll compressor geometry for quieter operation and higher reliability compared to reciprocating models.

Is the Danfoss 120U1296 compatible with R22 systems?
No, this unit is specifically designed for R410A refrigerant and high-pressure applications. Retrofitting into an R22 system is not recommended due to pressure and oil compatibility differences.

What electrical components are required for installation?
This residential HVAC compressor utilizes spade terminals for electrical connections. Technicians should verify the run capacitor and contactor ratings match the 208-230V 1-phase specifications before startup.

Can I use POE oil instead of the pre-charged PVE oil?
The 120U1296/HRH051U1LP6 comes charged with PVE oil. While some technicians mix oils, following manufacturer specs for PVE is recommended to maintain the integrity of the 51,000 BTU/h compressor performance.
