The Danfoss MTZ32-4VI (also identified as MTZ32JF4BVE) is a heavy-duty, single-cylinder reciprocating compressor designed for medium-temperature commercial refrigeration. Built for versatility, this unit is compatible with a wide array of refrigerants, including R404A, R407C, R134A, R448A, and R452A, making it a reliable choice for retrofitting or new installations. Operating on a 380-400V/3ph/50Hz or 460V/3ph/60Hz power supply, it delivers a cooling capacity of 20,949 Btu/h on R134a (at 45°F/130°F) and 17,480 Btu/h on R404A (at 20°F/120°F). The assembly features Rotolock connections, specifically a 1 1/4" suction and 1" discharge, both supplied with ODF solder sleeves for secure integration. Pre-charged with 0.95 liters of polyester oil (POE), the MTZ32-4VI includes an internal overload protector and a 3/8" NPT oil equalization port, ensuring stable performance in multi-compressor racks or standalone condensing units. Key Benefits for Technicians: Multi-Refrigerant Certification: Simplifies inventory by supporting R404A, R134A, R407A/C/F, R448A, R449A, R452A, and R513A. High-Ambient Reliability: Engineered with a large internal free volume to protect against liquid slugging and ensure refrigeration compressor longevity. Flexible Connection Options: Features Rotolock valves and solder sleeves to accommodate various piping configurations and facilitate faster field replacements. Robust Electrical Design: IP55 rated terminal box provides superior protection in demanding mechanical room environments. Common Questions Regarding the Danfoss MTZ32: What is the difference between Danfoss MT and MTZ series? The MT series uses mineral oil for CFC/HCFC refrigerants like R22, while this MTZ32-4VI is charged with 160PZ polyester oil for HFC, HFO, and blend refrigerants. Can this compressor replace a 1-phase unit? No, this is a 3-phase HVAC compressor; verify your site voltage is 460V (60Hz) or 400V (50Hz) before installation. Does it include mounting hardware? Yes, the Danfoss MTZ32-4VI ships with a mounting kit, including rubber grommets, nuts, and sleeves to minimize vibration transfer. This item is not eligible for free shipping.
