Maneurop Hermetic Reciprocating Compressor | MTZ56-4VM | 3-Phase | R404A/R134a/R407C
Product Description: The MTZ56-4VM is a core model in the Danfoss Maneurop MTZ series, specifically optimized for use with HFC refrigerants such as R404A, R134a, R407C, and R407A. In the UAE—where stable cooling is vital for food safety and industrial processes—the MTZ56 excels due to its large internal free volume, which provides industry-leading protection against liquid refrigerant slugging. The “-4VM” designation indicates it is designed for 380-400V 3-Phase (50Hz) power, ensuring the high starting torque and balanced electrical efficiency required for industrial sites in Dubai, Abu Dhabi, and Sharjah. Its 100% suction-gas cooled motor ensures the unit stays cool even when outdoor temperatures reach peak summer levels.
Key Features & Benefits:
- HFC & POE Optimized: Pre-charged with 160PZ POE oil, making it perfectly compatible with modern environmentally friendly refrigerants.
- Superior Liquid Handling: The large internal housing acts as a built-in accumulator, preventing mechanical damage from liquid refrigerant return.
- Industrial 3-Phase Performance: Offers high efficiency and stable operation for continuous-duty commercial refrigeration racks and chillers.
- Rotolock Flexibility: Equipped with Rotolock valves to allow for rapid installation and easy maintenance without extensive pipework modification.
- High Ambient Resilience: Specifically engineered to perform under the high-pressure conditions typical of the Middle Eastern climate.
