Danfoss MT64-1VI Compressor

The Danfoss MT64-1VI Maneurop compressor is a heavy-duty reciprocating compressor engineered for medium to high evaporating temperature applications using R22 refrigerant. Designed for high-reliability industrial and commercial refrigeration cycles, this 5.5 HP 230V 1-phase HVAC compressor features a 108.29 cm3/rev displacement and a robust 1-3/4" Rotolock suction connection paired with a 1-1/4" discharge. As a Maneurop MT series motor, the MT64HM1-DVI is built with large internal free volume to handle liquid slugging risk better than scroll equivalents. The mineral oil (160P) lubrication system ensures consistent performance in commercial refrigeration systems, while the internal motor protection and high-efficiency valving provide stable operation under demanding thermal loads. For contractors replacing existing Maneurop units, ensure your system utilizes the correct mineral oil charge and verify the 208-230V single-phase power supply matches the 1-phase 60Hz technical specifications of this specific model to prevent starting torque issues.

• High Liquid Tolerance: Designed with a large internal volume to survive liquid refrigerant return without internal mechanical failure.
• Rotolock Connections: Features 1-3/4" in and 1-1/4" out threaded connections for simplified piping and rapid field replacement.
• Reliable Motor Cooling: Suction gas-cooled motor design ensures thermal stability even during high-load cycles in ambient-intensive environments.
• Optimized for R22: Specifically valved and lubricated with 160P mineral oil for peak performance in legacy R22 medium-temp systems.

Is the MT64-1VI compatible with POE oil for HFC refrigerants?
No, the MT series is factory-charged with mineral oil for R22. For R404A or R407C applications, you must use the MTZ series which is optimized for polyolester oil.

What are the electrical requirements for this 1-phase model?
This unit requires a 208-230V single-phase supply. Always verify the run capacitor and start relay specifications to ensure the high starting torque required for reciprocating loads is met.

Can I use this compressor in low-temperature applications?
The MT64 is rated for medium to high evaporating temperatures. Using this model in low-temp evaporator configurations may lead to insufficient motor cooling and eventual failure.
