Danfoss MTZ160-4VI Compressor

The Danfoss MTZ160-4VI is a heavy-duty hermetic reciprocating compressor specifically engineered for medium-temperature commercial refrigeration applications. This 4-cylinder unit, also identified as model MTZ160HW4AVE, is designed for high-ambient reliability and broad application flexibility. It is fully compatible with a wide range of refrigerants, including R404A, R134a, R407C, R407F, R448A, R449A, R452A, and R513A. Operating on a 380-400V 3-phase 50Hz / 460V 3-phase 60Hz power supply, it delivers a cooling capacity of 107,631 BTU/h for R134a and 87,421 BTU/h for R404A/R507A under standard rating conditions. The internal 175PZ polyester oil charge ensures proper lubrication for HFC and HFO blends. For installation, the compressor utilizes 1 3/4" Rotolock suction and 1 1/4" Rotolock discharge connections with ODF sweat sleeves, alongside a 3/8" NPT oil equalization port for parallel racking configurations.

• Multi-Refrigerant Versatility: Certified for use with modern low-GWP refrigerants and legacy HFC blends, reducing inventory complexity for contractors.
• Robust Motor Protection: Features internal overload protection and an IP54-rated terminal box to prevent failures in demanding mechanical rooms.
• Drop-in Replacement Compatibility: Exact replacement for MTZ160HW-4AVE, ensuring seamless piping and electrical alignment during field retrofits.
• High-Capacity Performance: Optimized 4-cylinder design provides stable evaporating temperatures in supermarket display cases and walk-in cold rooms.
• Complete Mounting Kit: Ships with grommets, bolts, nuts, and sleeves to ensure a secure, vibration-dampened installation from the start.

What is the LRA and MCC for the MTZ160-4VI?
This compressor has a Locked Rotor Amp (LRA) rating of 130 A and a Maximum Continuous Current (MCC) of 36 A, requiring appropriate contactor and breaker sizing.

Can this compressor be used in parallel systems?
Yes, the unit is equipped with a 3/8" NPT oil equalization connection, making it suitable for manifolding in multiple compressor racks.

Which oil should be used for top-offs?
The MTZ series is factory-charged with Danfoss 175PZ POE oil. Always verify oil compatibility when retrofitting or servicing systems using HFC/HFO refrigerants.
