Maneurop MT/MTZ Series Piston CompressorsI. Product Overview The MT and MTZ series are hermetic piston compressors specifically designed for medium- and high-temperature refrigeration and heat pump applications. Known for high reliability, a broad operating range, and long service life, these compressors are suitable for various industrial and commercial scenarios, including commercial refrigeration, display freezers, cold storage, and heat pump systems. Precision manufacturing processes and high-quality materials ensure stable performance under complex operating conditions. II. Core Design and Technical Features
Wide Operating Range and High Adaptability Designed for medium- to high-temperature applications, these compressors operate stably across a wide range of evaporation and condensation temperatures. They are compatible with multiple refrigerants (e.g., R404A, R134a, R448A) and various system configurations.
Reinforced Structural Design and Liquid Slugging Resistance The MT/MTZ series features an optimized cylinder structure and internal volume design, enhancing tolerance to refrigerant return and improving resistance to liquid slugging. This reduces the risk of failure caused by system fluctuations.
High-Efficiency Ring Valve System Equipped with a low-resistance ring valve structure to improve gas flow efficiency, minimize energy loss, and ensure efficient operation under varying load conditions.
Full Suction Gas Cooling Technology The compressors utilize a fully suction-gas-cooled design, eliminating the need for external cooling fans or additional devices. This simplifies system integration, allows for the addition of external sound insulation covers for quieter operation, and prevents motor overheating.
High-Torque Motor and Starting Performance The built-in high-torque motor ensures reliable starting under voltage fluctuations or low-temperature environments, making it suitable for applications with frequent starts/stops or varying loads.
Lubrication System and Refrigerant Compatibility • The MT series uses mineral oil, making it suitable for traditional refrigerant systems. • The MTZ series uses ester oil (POE), compatible with HFO and HFC environmentally friendly refrigerants. It offers excellent refrigerant adaptability and can directly replace older Maneurop® MTE compressors, facilitating system upgrades and retrofits.
III. Reliability and Long Service Life All critical components are manufactured from high-strength, wear-resistant materials. Combined with precision engineering and strict quality control, these compressors maintain low failure rates and extended service life, even under long-term high-load operations. IV. Typical Applications • Medium- and high-temperature commercial refrigeration systems (e.g., supermarket display cases, beverage coolers) • Industrial cold storage and logistics cold chain equipment • Heat pump water heating systems and heating units
