Danfoss MT160-4VI Compressor

The Danfoss MT160-4VI is a heavy-duty R22 reciprocating compressor engineered for medium and high-temperature refrigeration and air conditioning applications. Built for 460V 3-phase 60Hz (or 380-400V 50Hz) power supplies, this Maneurop MT series compressor delivers a nominal capacity of 156,820 Btu/h under standard ARI conditions. Designed with a massive internal volume to handle liquid slugging, it utilizes 160 mineral oil for lubrication, ensuring long-term reliability in demanding commercial environments. Technical connections include a 1-3/4" Rotolock suction with a 1-1/8" ODF sleeve and a 1-1/4" Rotolock discharge with a 3/4" ODF sleeve, alongside a 3/8" NPT oil equalization port for parallel racking. This hermetic unit is the industry standard for commercial refrigeration compressor replacement, offering superior thermal protection and mechanical resistance against high discharge temperatures often encountered in older R22 systems.

Key Benefits

• Large Internal Volume: High tolerance for liquid refrigerant return, reducing mechanical wear during flooded starts.
• Rotolock Connections: Simplifies field installation and maintenance with secure, threaded fittings.
• Dual-Frequency Compatibility: Operates efficiently on both 50Hz and 60Hz power grids for versatile application use.
• Mineral Oil Lubrication: Optimized specifically for R22 chemical profiles to maintain consistent viscosity and return.
• Robust Suction Gas Cooling: Internal motor geometry utilizes suction gas to dissipate heat, extending component life.

Common Questions

What is the best way to handle oil equalization on this model?
The MT160-4VI features a dedicated 3/8" NPT port for oil equalization, which is essential for maintaining proper crankcase levels when used in manifolded rack systems.

Can I use this compressor with R407C or other HFCs?
The "MT" series is factory-charged with mineral oil and designed for R22. For HFC retrofits, the "MTZ" series with POE oil is required. Mixing oils or using R22 compressors with HFCs can lead to lubrication failure.

How do I ensure proper electrical phasing?
Since this is a 3-phase motor, verifying rotational direction via suction and discharge pressure differentials is critical at startup to prevent internal damage.
