Danfoss MT50-3VI Compressor

The Danfoss MT50-3VI is a medium-temperature Maneurop reciprocating compressor engineered for high-suction gas cooled environments. Operating on a 200-230V 3-phase power supply at 60Hz, this unit delivers a nominal capacity of 50,503 BTU/hr when utilized with R22 refrigerant. Designed for durability in commercial refrigeration and process cooling, the MT50-3VI features a large internal free volume that provides superior resilience against liquid slugging. The mineral oil (160P) lubrication system is optimized for HCFC applications, ensuring consistent piston and bearing protection. This workhorse model utilizes rotolock connections for straightforward field installation and serviceability. With its four-cylinder design, the compressor maintains high volumetric efficiency across a broad operating envelope, making it a reliable drop-in replacement for existing medium-temperature mechanical systems requiring a robust 230V 3-phase configuration.

• High Thermal Stability: The 100% suction gas-cooled motor prevents overheating during heavy-duty cycles.
• Liquid Handling: Large internal volume protects the mechanical assembly from occasional liquid floodback.
• Standardized Fit: Features industry-standard rotolock ports and mounting footprints for rapid swaps.
• Durable Crankshaft: Reinforced internal components designed for continuous operation in demanding environments.
• Acoustic Performance: Internal discharge mufflers reduce gas pulsation and operational vibration.

Is the MT50-3VI compatible with POE oil for HFC conversions?
This specific model comes pre-charged with 160P mineral oil for R22. For HFC refrigerants like R404A or R134a, the MTZ series with POE oil is required.

What are the specific port sizes for this compressor?
The MT50-3VI typically utilizes a 1-3/4" rotolock suction connection and a 1-1/4" rotolock discharge connection.

Does this unit require a crankcase heater?
For outdoor installations or systems where refrigerant migration is a concern, a 65W or 75W PTC crankcase heater is recommended to maintain oil integrity.
