Danfoss MT72-4VI Compressor

The Danfoss MT72-4VI Compressor is a 6 HP reciprocating compressor engineered for medium-to-high temperature refrigeration and HVAC applications. Operating on a 460V 3-phase power supply at 60Hz (400V/50Hz), this Maneurop series unit delivers high volumetric efficiency through its signature circular valve design and large internal volume, which provides excellent liquid hammer resistance. Field-proven as a reliable R22 refrigeration compressor, the MT72-4VI is factory-charged with 160P mineral oil to maintain optimal lubrication across extended operating envelopes. Its robust 2-cylinder construction features Rotolock connections (1-3/4" suction, 1-1/4" discharge) for streamlined installation and maintenance in commercial environments. With a 3500 RPM motor and internal overload protection, this Danfoss 460V 3ph compressor is built to withstand rigorous duty cycles while maintaining consistent capacity in field-service replacements or new builds. Professional contractors rely on this hermetic reciprocating compressor for its high-torque motor performance and compatibility with traditional mineral-oil-based systems.

• Enhanced Liquid Handling: High internal volume and 2-cylinder design minimize the risk of damage from liquid slugging during startup or defrost cycles.
• Superior Gas Management: The circular valve plate design reduces internal pressure losses and improves overall volumetric efficiency.
• Simplified Integration: Equipped with standard Rotolock fittings and a threaded sight glass for quick oil level verification and system connections.
• Durable Motor Protection: Features internal motor protection to safeguard the 6 HP motor against electrical fluctuations and overheating.

Is the MT72-4VI compatible with POE oil for HFC refrigerants?
No, the MT series is specifically designed for use with mineral oil and R22. If your application requires HFCs like R404A or R407C, the MTZ72-4VI (POE charged) is the appropriate alternative.

What are the specific port sizes for suction and discharge?
This unit features a 1-3/4 inch Rotolock suction connection and a 1-1/4 inch Rotolock discharge connection, typically used with 7/8 inch and 3/4 inch ODF sleeves respectively.

Can this compressor be used in parallel rack systems?
Yes, the VE version of the 6hp Danfoss compressor includes an oil equalization port and sight glass, making it suitable for multi-compressor rack configurations.
