Danfoss MT32-1VI Compressor

The Danfoss MT32-1VI Maneurop MT series compressor is a high-performance R22 reciprocating compressor designed for medium and high evaporating temperature applications. Operating on 208-230V single-phase power, this unit delivers a nominal 33,044 Btu/h cooling capacity at standard ARI conditions (45°F evaporator / 130°F condenser). Designed as a direct replacement for COM3690, it features 1-1/4" Rotolock suction and 1" Rotolock discharge ports, pre-configured with 5/8" and 1/2" ODF sweat sleeves for field flexibility. The internal motor protection and large internal free volume allow this Maneurop MT32-1VI compressor to handle liquid slugging and high return gas temperatures better than standard hermetic units. Utilizing mineral oil (160P), it is engineered for field-proven reliability in demanding HVAC refrigeration systems. This single-phase HVAC compressor includes a 3/8" NPT oil equalization port, making it suitable for parallel rack or tandem installations where maintaining consistent oil levels is critical.

• High Liquid Tolerance: Large internal volume and robust valve plates handle liquid refrigerant carryover without mechanical failure.
• Standardized Fit: Rotolock fittings allow for quick installation and easy integration into existing R22 systems.
• Field Versatility: Direct drop-in MT32 replacement for various OEM brands and the legacy COM3690 model.
• Thermal Protection: Internal line break motor protection prevents overheating during high-compression cycles.

Common Questions

Is the Danfoss MT32-1VI compatible with POE oil for R407C conversion?
This specific model comes charged with mineral oil for R22. If converting to R407C or other HFCs, the oil must be thoroughly flushed and replaced with 160PZ POE oil to ensure proper lubrication and miscibility.

Can this compressor replace a standard hermetic pot compressor?
Yes, provided the frame size and Btu/h rating align. The MT32-1VI offers superior durability in harsh environments compared to standard light-duty hermetic units.

What are the wiring requirements for this single-phase model?
The MT32-1VI requires a permanent split capacitor (PSC) or start kit setup depending on the system's starting torque requirements. Always verify the run capacitor MFD rating against the nameplate before energizing.
