Danfoss 120F0238 Compressor

When you are looking for a high-performance solution for low-temperature applications, the Danfoss 120F0238 NTZ108A4LR1A is the industry standard for reliability. Built as a hermetic reciprocating compressor, this unit is engineered specifically for low evaporating temperature (LT) systems, operating efficiently with R404A and R507A refrigerants. This 460V/3Ph workhorse serves as the direct replacement for the legacy Danfoss 120F0004, ensuring a seamless drop-in fit for existing refrigeration racks and walk-in freezers. Its 108cc swept volume and 2-cylinder design provide the suction gas cooled motor protection needed to handle harsh operating cycles without the need for liquid injection.

The Maneurop NTZ series is optimized for performance at -30°F, featuring a large internal free volume that effectively mitigates the risk of liquid hammering. Technicians appreciate the Rotolock connections (1 3/4" suction, 1 1/4" discharge) which simplify field piping and component swaps. With a maximum continuous current of 12.1A and internal overload protection, this low temperature refrigeration compressor maintains high volumetric efficiency throughout its extended evaporating range of -50°F to +15°F.

• Direct Replacement: Fully replaces discontinued 120F0004 models with identical mounting footprints.
• Refrigerant Versatility: Qualified for use with R404A, R507, and R452A for modern compliance.
• Robust Design: 100% suction-gas cooled motor ensures lower operating temperatures and longer component life.
• Technical Precision: Equipped with a 3/8" flare oil equalization port and a threaded sight glass for fast oil level diagnostics.
• Simplified Installation: Standard Rotolock fittings allow for quicker brazing and decreased system downtime.

Common Questions

Is the 120F0238 compatible with R507?
Yes, the Danfoss NTZ108A4LR1A is fully qualified for R404A/R507 and R452A using 175PZ polyolester oil.

What are the electrical requirements for this model?
This unit requires 460V / 3-Phase / 60Hz (also rated for 400V / 3-Phase / 50Hz) and features an internal overload protector for motor safety.

Does this unit require additional cooling for low-temp operation?
No, the Maneurop NTZ design is a "true" low-temp compressor; its suction-gas cooled motor removes the need for external blowers or liquid injection under standard LT conditions.
