Danfoss MT50-4VI Compressor

The Danfoss MT50-4VI is a heavy-duty Maneurop reciprocating compressor engineered for medium to high evaporating temperature applications. Operating on 460V 3-phase power, this 4.5 HP unit is a reliable replacement for commercial refrigeration and air conditioning systems. Designed specifically for use with R22 refrigerant and mineral oil, the MT series features a high internal free volume that provides superior resilience against liquid slugging. The low pressure side design ensures cool suction gas passes over the motor, maintaining optimal operating temperatures during high-demand cycles. For contractors performing a retrofit or repair, the rotalock connections facilitate straightforward piping integration. This compressor is built with high-grade valve plates and internal protection to handle the rigors of commercial HVACR service. Prioritize checking the starting capacitor and contactor during installation to ensure the R22 refrigeration compressor operates within specified voltage tolerances for long-term field stability.

• Liquid Handling: Large internal volume protects the reciprocating compressor against damage from liquid refrigerant migration.
• Durable Construction: Built with robust internal components to withstand frequent cycling in industrial refrigeration environments.
• Thermal Management: Suction gas cooled motor design reduces winding stress and prevents overheating during peak load.
• Ease of Installation: Standard Danfoss MT50 footprint and rotalock fittings simplify drop-in replacements for field technicians.

What oil should be used with the MT50-4VI?
This model is factory-charged with mineral oil, specifically intended for use with R22 refrigerant circuits. If converting to an HFC refrigerant, a dedicated MTZ polyolester (POE) series compressor should be used instead.

Are the rotalock valves included with this unit?
Typically, rotalock valves and gaskets are sold separately. It is recommended to replace gaskets during every installation to ensure a leak-free seal on the suction and discharge lines.

Can this compressor handle low-temp applications?
The MT series is optimized for medium and high evaporating temperatures. For low-temp freezer applications, the LT series is the appropriate technical selection to ensure proper mass flow and cooling.
