Danfoss 121L3347 Scroll Compressor

The Danfoss 121L3347 Scroll Compressor, known professionally as model HRP047T1LP6, is a high-performance hermetic solution engineered specifically for residential and light commercial air conditioning applications. This 47,000 BTU scroll compressor operates on a 208-230V, single-phase, 60Hz power supply and is optimized for use with R22 and R407C refrigerants. As a veterans’ choice for field reliability, this unit serves as the direct Danfoss HRP047T1LP6 replacement for legacy models including the 120U0951, HRM045U1LP6, and S1-015-03710-004.

Designed for durability in demanding environments, this 3.9-ton HVAC compressor features a fixed-speed scroll mechanism that ensures quiet operation and smooth refrigerant flow. The HRP series Danfoss compressor comes pre-charged with 1.33 liters of PVE oil (160HV), which is critical for maintaining lubrication and compressor longevity when using HFC and HCFC blends. The unit utilizes industry-standard brazed ODF connections, with a 3/4" suction and 1/2" discharge, facilitating a seamless drop-in fit for technicians performing system retrofits or repairs.

Common Questions Regarding the Danfoss 121L3347

What is the primary difference between the HRP and legacy HRM models?
The HRP series, such as the HRP047T1LP6, is built with PVE oil rather than mineral oil, making it fully compatible with newer R407C refrigerants while maintaining support for R22 service applications.

Can this compressor be used for new installations?
Per EPA regulations regarding restricted HCFC refrigerants, if used with R22, this compressor is intended for servicing and repairing existing infrastructure only.

What capacitors are required for this single-phase motor?
Installation typically requires a 60 µF run capacitor (370VAC) and a 100MFD start capacitor for optimal torque during the start sequence.
