Danfoss MTZ36-4VI Compressor

The Danfoss MTZ36-4VI is a professional-grade hermetic reciprocating compressor specifically engineered for medium and high evaporating temperature applications in commercial refrigeration. This 3-HP unit is chemically and mechanically identical to the MTZ36JG4AVE, providing a direct drop-in replacement for contractors servicing Danfoss Maneurop systems. Optimized for use with POE (Polyester) oil, the compressor offers broad refrigerant flexibility, supporting R404A, R407C, R134A, R407F, and R507A. This versatility makes it an ideal refrigeration compressor replacement for a wide array of existing equipment.

Built for global compatibility, the MTZ36-4VI features a versatile motor design capable of operating on 380-400V 3-Phase 50Hz or 460V 3-Phase 60Hz electrical supplies. Performance benchmarks include a capacity of 24,482 Btu/h when utilizing R134a (at 45°F evaporator and 130°F condenser) and 20,189 Btu/h with R404A/R507A (at 20°F evaporator and 120°F condenser). The hermatic compressor is equipped with a 1-1/4" Rotolock suction connection (5/8" ODF sleeve) and a 1" Rotolock discharge connection (1/2" ODF sleeve), along with a 3/8" NPT oil equalization port to facilitate parallel installations. Its internal motor protection and circular valve design ensure high volumetric efficiency and protection against liquid hammering during intensive duty cycles.

• Multi-Refrigerant Compatibility: Engineered for seamless operation with R404A, R134A, R407C, and other modern HFCs using Polyester Oil.
• Robust Protection: Features a high-volume internal design that mitigates the risk of liquid hammering, extending the service life in demanding environments.
• Dual Frequency Motor: High-torque motor supports both 50Hz and 60Hz 3-phase power, suitable for international and domestic industrial applications.
• Simplified Connection: Standard Rotolock fittings with sweat sleeves allow for faster field installation and reliable sealing.

Is the Danfoss MTZ36-4VI a direct replacement for the MTZ36JG4AVE?
Yes, the MTZ36-4VI is the identical technical equivalent to the MTZ36JG4AVE model, sharing the same physical dimensions, electrical requirements, and performance curves.

Can this compressor be used with R22?
No, the MTZ series is specifically designed for HFC refrigerants and comes pre-charged with POE oil. For R22 applications, the MT series (using mineral oil) is the appropriate choice.

What is the purpose of the 3/8" NPT connection?
This is an oil equalization port used primarily in tandem or manifolded compressor racks to maintain consistent oil levels across multiple units.
