The Danfoss MT72-3VI is a heavy-duty R22 reciprocating compressor designed for medium and high evaporating temperature applications in commercial refrigeration and air conditioning systems. Operating on a 200-230V 3-phase 60Hz power supply, this Maneurop Series unit delivers a nominal cooling capacity of 74,561 Btu/h under standard ARI conditions (45°F evaporator, 130°F condenser). Built with high-grade internal components to handle liquid slugging, the MT72-3VI utilizes 160P mineral oil for superior lubrication and thermal stability. The physical interface includes a 1-3/4" Rotolock suction port with a 7/8" ODF sweat sleeve and a 1-1/4" Rotolock discharge port with a 3/4" ODF sleeve, ensuring high-pressure seal integrity. This model also features a 3/8" NPT oil equalization connection, making it ideal for parallel rack installations where oil management between multiple compressors is critical for system longevity. For technicians performing a Danfoss MT72-3VI replacement, the large internal volume provides excellent resistance to liquid return, maintaining reliability in demanding environments. High Thermal Stability: Engineered specifically for R22 refrigerant systems using 160P mineral oil to minimize carbonization at high discharge temperatures. Robust Liquid Handling: The Maneurop reciprocating compressor design features a large internal free volume that protects against liquid hammer. Versatile Professional Grade: Includes a 3/8" NPT oil equalization port, allowing for seamless integration into multi-compressor parallel systems. Standardized Fitment: The 74,561 Btu/h capacity and 200-230V 3-phase electrical profile match a wide range of commercial HVACR condensers. Secure Connections: Industry-standard Rotolock fittings with ODF sweat sleeves provide leak-resistant transitions for suction and liquid lines. Common Questions What are the specific port sizes for the MT72-3VI? This compressor utilizes a 1-3/4" Rotolock suction connection (7/8" ODF sleeve) and a 1-1/4" Rotolock discharge connection (3/4" ODF sleeve). Can this compressor be used with POE oil for R407C retrofits? The MT72-3VI is factory-charged with mineral oil for R22. For R407C or other HFC applications, the MTZ series with POE oil is generally the specified alternative. Is this model suitable for parallel rack configurations? Yes, the inclusion of the 3/8" NPT oil equalization connection allows this unit to be piped into a shared oil management system across multiple compressors. This item must ship via truck.
