Danfoss MTZ22-1VI Compressor

The Danfoss MTZ22-1VI Compressor is a professional-grade hermetic reciprocating compressor specifically engineered for medium and high-temperature refrigeration applications. Designed to handle a versatile range of refrigerants including R404A, R407C, R134A, and R407F, this Maneurop MTZ series unit is pre-charged with polyester oil (POE) to ensure optimal lubrication and compatibility with HFC systems. Running on a 208-230V single-phase 60Hz power supply, it delivers a robust cooling capacity of 14,849 Btu/h on R134a and 12,306 Btu/h on R404A/R507A under standard operating conditions. The large internal free volume provides superior protection against liquid hammering, while the 100% suction gas-cooled motor ensures reliable thermal management even in demanding environments. Featuring 1 1/4" Rotolock suction and 1" Rotolock discharge connections with ODF sweat sleeves, this unit simplifies field installation for contractors requiring a high-torque, durable solution for replacement or new builds.

• Multi-Refrigerant Compatibility: Fully rated for R134a, R404A, R407C, and R407F, providing maximum flexibility for various system retrofits.
• Enhanced Durability: The Danfoss Maneurop design features a large internal volume to mitigate risks associated with liquid slugging and mechanical wear.
• Efficient Thermal Management: Gas-cooled motor design ensures consistent cooling across the electrical windings, extending the compressor motor life cycle.
• Simplified Installation: Technical Rotolock connections with sweat sleeves allow for faster piping and secure sealing in the field.
• Integrated Oil Management: Equipped with a 3/8" NPT oil equalization port, making it ideal for parallel rack configurations or oil level monitoring.

Can I use this compressor to replace an older MT series unit?
The MTZ series is designed for HFC refrigerants and uses polyester oil (POE). While physically similar to the MT series (which uses mineral oil for R22), you must ensure the system is properly flushed and converted if switching between lubricant types to avoid mechanical failure.

What are the specific port sizes for suction and discharge?
This unit utilizes a 1 1/4" Rotolock suction port with a 5/8" ODF sleeve and a 1" Rotolock discharge port with a 1/2" ODF sleeve.

Is a crankcase heater required for this model?
While not always included, a crankcase heater is highly recommended for any HVACR refrigeration compressor installed in ambient conditions where refrigerant migration could occur during the off-cycle.
