Danfoss MTZ100-4VI Compressor

The Danfoss MTZ100-4VI is a heavy-duty Maneurop reciprocating compressor designed for medium and high-evaporating temperature applications. Engineered for versatility, this commercial refrigeration compressor is charged with polyester oil (POE), making it fully compatible with R404A, R407C, R134A, and R407F refrigerants. Operating on a 380-400V/3PH/50Hz or 460V/3PH/60Hz power supply, it delivers a robust 63,936 Btu/h using R134a and 52,953 Btu/h using R404A/R507A under standard ARI conditions. This unit serves as a direct MTZ100-4VM cross reference, featuring a 1 3/4" Rotolock suction connection with a 1 1/8" ODF sleeve and a 1 1/4" Rotolock discharge with a 3/4" ODF sleeve. Professionals seeking a reliable Danfoss MTZ100-4VI replacement will appreciate the internal motor protection and high-volume internal pressure shell, which provides excellent resistance to liquid slugging during demanding cycles.

• Multi-Refrigerant Compatibility: Supports R134a, R404A, R407C, and R507A, simplifying inventory and field retrofits.
• Rotolock Valving: Simplifies installation and maintenance with 1-3/4" suction and 1-1/4" discharge ports.
• Oil Equalization: Includes a 3/8" NPT connection for stable oil management in parallel rack configurations.
• Efficient Thermal Management: 100% suction-gas cooled motor ensures lower operating temperatures and long-term winding integrity.

Can the MTZ100-4VI handle low-temperature applications?
This model is optimized for medium to high evaporating temperatures. For dedicated low-temp racks, verify the mass flow requirements and operating envelope to ensure the internal motor cooling remains sufficient.

Is this compressor compatible with mineral oil?
No. The MTZ series is explicitly designed for use with POE oil and HFC refrigerants. If your system still utilizes HCFCs and mineral oil, refer to the MT series equivalent.

What is the difference between the 4VI and 4VM designations?
The MTZ100-4VI is the current technical cross for the 4VM. While primary performance specs are identical, always verify the port orientations and electrical terminal box placement during a field swap.
