Danfoss MTZ22-3VI Compressor

The Danfoss MTZ22-3VI is a professional-grade hermetic reciprocating compressor engineered specifically for medium and high evaporating temperature applications. Operating on a 200-230V 3-phase power supply, this 2 HP Maneurop compressor delivers robust performance across a versatile range of HFC refrigerants, including R134a, R404A, R407C, and R507A. Utilizing 175PZ polyolester (POE) oil, the MTZ22-3VI features a high-torque motor design and a large internal free volume that effectively mitigates the risk of liquid hammering. The 100% suction-gas cooled motor ensures thermal stability without the need for additional airflow, making it an ideal drop-in for commercial refrigeration and air conditioning plant maintenance. With a 1-inch Rotolock connection and a 3500 RPM rotational speed at 60Hz, this unit provides dependable volumetric efficiency for demanding contractor installations.

• Multi-Refrigerant Compatibility: Designed for seamless operation with R134a, R404A, R407A/C/F, R448A, R449A, and R452A, providing maximum field flexibility.
• Advanced Motor Protection: Includes an internal overload protector to prevent winding failure during high-load or off-cycle ambient spikes.
• Liquid Handling Capabilities: The large shell design and circular valve technology allow the unit to handle liquid refrigerant return better than standard scroll alternatives.
• Simplified Installation: Standardized 1-inch Rotolock suction and discharge ports allow for fast replacement in existing Maneurop footprints.

What is the difference between MT and MTZ Maneurop compressors?
Technically, both series share the same mechanical design and high-torque motor. The critical difference is the lubricant; the MTZ22-3VI is factory-charged with POE oil for HFC refrigerants, whereas the MT series uses mineral oil for R22 applications.

Does this compressor require a crankcase heater?
While the 100% gas-cooled motor provides excellent thermal management, a PTC crankcase heater is highly recommended for systems where the compressor is exposed to low ambient temperatures to prevent refrigerant migration during the off-cycle.

Can I use this compressor in a single-phase system?
No. The MTZ22-3VI is a 3-phase motor. Attempting to wire this to a single-phase supply, even with a start kit, will result in immediate motor failure and winding burn-out.
