Danfoss 195B0059 Compressor Kit

The Danfoss 195B0059 Compressor Kit is the high-performance SC18G 220V R134a solution designed for demanding commercial refrigeration applications. As a direct 104G8820HS replacement, this hermetic reciprocating compressor features a high starting torque (HST) motor, ensuring reliable starts under differential pressure—critical for MBP and HBP systems. Built with a 17.70 cc displacement, it delivers a robust cooling capacity of approximately 6,000 BTU/h, making it a staple for walk-in coolers and display cases.

Engineered for technical precision, the Danfoss 195B0059 utilizes a CSIR motor configuration and is optimized for POE lubricant. This kit includes the necessary electrical components—such as the start capacitor and potential relay—to streamline field installation. Its 1/2 HP rating and 220-230V 50/60Hz dual-frequency compatibility provide the versatility needed for diverse international and domestic industrial environments, maintaining stable refrigerant R134a evaporation across a wide temperature range.

Key Benefits for Contractors:

• Universal Compatibility: Serves as the updated equivalent for the legacy 104G8820HS, fitting standard mounting footprints without extensive piping modification.
• Enhanced Starting Reliability: The HST (High Starting Torque) design prevents stalls during heavy-duty cycles in high-ambient conditions.
• Efficiency Optimized: Specifically tuned for R134a systems to provide high COP (Coefficient of Performance) and reduced energy consumption.
• Complete Installation Kit: Comes with pre-matched electrical accessories to ensure motor protection and optimal starting characteristics.
• Low Noise Signature: Designed with internal vibration damping to meet noise constraints in commercial environments.

Common Technical Questions:

Does this compressor require a specific oil type?
Yes, the SC18G is designed for use with Polyol Ester (POE) oil to ensure proper lubrication and return when used with HFC refrigerants like R134a.

Is this a drop-in replacement for the 104G8820HS?
The 195B0059 is the official updated version. While it maintains the same technical performance metrics, always verify the footprint and port sizes (Suction: 10.2mm, Discharge: 6.2mm) before brazing.

Can I use this for Low Back Pressure (LBP) applications?
While optimized for MBP/HBP, the SC18G has a broad operating envelope; however, always consult the specific Danfoss technical datasheet for mass flow and capacity ratings at LBP setpoints.
