Danfoss MT64-3VI Compressor

The Danfoss MT64-3VI is a professional-grade hermetic reciprocating compressor specifically designed for medium temperature refrigeration and HVAC applications. This R22 compressor, also identified as OEM model MT64HM3DVE, delivers a robust cooling capacity of 64,366 BTU/h under standard rating conditions (45°F evaporator / 130°F condenser). Engineered for 200-230V, 3-phase, 60Hz systems, this unit utilizes 160P mineral oil and features a dual-cylinder design for balanced operation and long-term reliability in demanding commercial environments.

This Maneurop MT series compressor is built with a high-torque motor capable of a 137A Locked Rotor Amps (LRA) and a 29A Maximum Continuous Current (MCC). Pipe integration is streamlined via 1-3/4" Rotolock suction and 1-1/4" Rotolock discharge ports, provided with 7/8" and 3/4" ODF sleeves respectively. For manifold configurations, the unit includes a 3/8" NPT oil equalization port. Its IP55-rated terminal box and internal motor protection ensure durability against electrical fluctuations and environmental stress.

Common Questions

What oil is factory-charged in the MT64-3VI?
This model is factory-charged with 1.8 liters of 160P mineral oil, specifically formulated for R22 systems to ensure proper lubrication and heat dissipation.

Can this compressor be used with R407C or R404A?
The MT series is designed for mineral oil and R22. For HFC refrigerants like R407C or R404A, the Danfoss MTZ series with POE oil must be used to ensure chemical compatibility.

Is the motor protection internal or external?
The MT64-3VI features internal line break protection that monitors both current and temperature to prevent motor burnout during phase loss or overload conditions.
