The Danfoss MT28-1VI Compressor is a 2.5 HP hermetic reciprocating compressor engineered for medium and high evaporating temperature applications. Operating on 230V single-phase power, this Maneurop series unit delivers a cooling capacity of approximately 16,370 BTU/h at a 20°F evaporator temperature. It is specifically optimized for R22 refrigerant using 160P mineral oil, though it can be adapted for R22-based blends when using alkylbenzene lubricant. The MT28-1VI features a 100% suction-gas cooled motor, which eliminates the need for external cooling and protects the internal components from overheating during high-demand cycles. Designed with a high-torque motor and large internal free volume, it provides superior resistance to liquid hammering. This model includes a VE configuration with an oil sight glass and a 3/8" flare oil equalization port, and it utilizes 1" rotolock suction and discharge connections for secure, leak-proof integration into commercial refrigeration and HVAC systems. Key Benefits Suction-Gas Cooled Motor: Ensures the 2.5 HP motor remains within optimal temperature ranges without requiring additional fans or airflow. Large Internal Volume: Minimizes the risk of mechanical damage caused by liquid refrigerant slugging. Versatile Application: Ideal for walk-in coolers, industrial process cooling, and medium-temperature refrigeration racks. Enhanced Monitoring: Integrated oil sight glass allows for immediate visual verification of lubricant levels during routine maintenance. High Torque Performance: Robust starting torque ensures reliable operation even under high-head pressure conditions. Common Questions What is the primary refrigerant and oil compatibility for the MT28-1VI? This unit is factory-charged with 160P mineral oil and is designed for R22. If retrofitting with R22 replacement blends, the oil must be replaced with 160 ABM alkylbenzene oil. Is this compressor compatible with R404A or R410A? No. The MT series is designed for HCFC applications. For HFC refrigerants like R404A or R134a, the MTZ series using polyolester (POE) oil is required. What electrical components are required for the single-phase motor? As a 230V 1ph unit, it requires a dedicated start capacitor and run capacitor suited for 2.5 HP loads to ensure proper starting torque and motor efficiency.
