The Danfoss MT22-4VI is a medium-to-high evaporating temperature reciprocating compressor designed for commercial refrigeration and process cooling applications. This 2 HP compressor operates on a 460V 3-phase 60Hz electrical supply, using mineral oil to maintain lubrication in systems running R22 refrigerant. Built with the Maneurop legacy of durability, the MT22-4VI features a large internal free volume to mitigate risk from liquid slugging, making it a reliable choice for HVACR contractors servicing walk-in coolers or industrial chillers. With its rotolock connections and high-torque motor, this Danfoss Maneurop MT series unit ensures consistent mass flow and thermal efficiency under demanding duty cycles. Utilizing Danfoss compressors with these specifications facilitates seamless drop-in replacements for legacy installations where voltage stability and suction gas cooling are critical for system longevity. Key Benefits for Technicians Large Internal Volume: High tolerance against liquid refrigerant migration and slugging during startup. Suction Gas Cooled: Efficient motor cooling ensures the unit remains within safe operating temperatures across varying load profiles. Robust Valve Design: Engineered to handle high pressure ratios without compromising volumetric efficiency. Versatile Application: Optimized for medium and high suction temperatures, perfect for food preservation and industrial cooling. Rotolock Ports: Simplifies field installation and maintenance for faster service turnaround. Common Technician Questions Is the MT22-4VI compatible with POE oil for HFC conversions? This specific model is the MT variant shipped with mineral oil for R22 systems. For HFC refrigerants like R404A or R134a, the MTZ series with POE oil is the required equivalent. What are the electrical requirements for this 460V 3-phase model? This unit is designed for 460V systems. Ensure your contactor and overloads are sized correctly for the Max Continuous Current (MCC) rating specified on the nameplate. Does this unit come with required mounting hardware? Yes, standard Danfoss MT compressors include the rubber mounting kit to minimize vibration transfer to the refrigeration rack or base.
