Maneurop Hermetic Reciprocating Compressor | MTZ22-4VM | 3-Phase
Product Description: The MTZ22-4VM is a key model in the Danfoss Maneurop MTZ series, specifically engineered for use with modern HFC refrigerants such as R404A, R134a, R407C, and R407A. In the UAE’s demanding high-ambient environment, the MTZ22 stands out for its robust construction and large internal free volume, which provides exceptional protection against liquid slugging. The “-4VM” designation indicates a 380-400V 3-Phase (50Hz) power supply, offering the balanced electrical load and high starting torque required for small industrial chillers, cold rooms, and milk cooling tanks in Dubai and Abu Dhabi. Its 100% suction-gas cooled motor ensures the unit operates safely even during the peak of the Middle Eastern summer.
Key Features & Benefits:
- HFC & POE Optimized: Factory-charged with 160PZ POE oil, ensuring perfect chemical compatibility with environmentally friendly refrigerants.
- Superior Liquid Handling: The large internal shell volume prevents mechanical damage by providing a massive safety buffer for returning liquid refrigerant.
- Industrial 3-Phase Power: Delivers higher energy efficiency and more stable operation for continuous-duty commercial use compared to single-phase versions.
- Rotolock Serviceability: Equipped with Rotolock suction and discharge ports for fast, clean, and flexible installation and maintenance.
- High Ambient Resilience: Specifically engineered to perform under the high-pressure conditions typical of the Middle Eastern T3 climate.
