The MT/MTZ series is a line of hermetic piston compressors from Danfoss, specifically designed for commercial refrigeration equipment. Renowned for its high robustness, strong resistance to liquid slugging, and suitability for frequent start-stop operations, this series is an ideal choice for applications such as refrigerated cabinets, display cases, and small cold storage rooms.
Core Design Features and Advantages
Robust and Durable Structure: Utilizing high-quality components and precision manufacturing processes, the MT/MTZ series ensures long-term, stable operation under demanding commercial environments, extending service life.
Excellent Operational Adaptability: ◦ Strong Resistance to Liquid Slugging: The compressor features a generously sized internal cavity designed to effectively buffer and handle minor liquid refrigerant return, protecting mechanical components. ◦ Wide Operating Range: Optimized for medium to high evaporation temperatures (typically for freezing, refrigeration, and air conditioning applications), enabling reliable performance across a broad range of ambient conditions. ◦ High-Load Start-Up Capability: The motor is engineered to meet the high-load start-up demands common in commercial applications, ensuring reliable performance during startup.
Efficient Internal Cooling and Protection: The motor is entirely cooled by low-temperature suction refrigerant vapor, offering high efficiency without requiring external cooling fans. The compressor integrates essential thermal and overload protection devices.
Low Noise and Vibration: Precision dynamic balancing and optimized operational curves ensure smooth and quiet operation. Some models are available with optional sound-absorbing covers to further reduce noise, meeting the requirements of noise-sensitive environments.
Flexible Power Supply Configuration: The series offers a wide range of power options, supporting both single-phase and three-phase power supplies, and is compatible with 50Hz and 60Hz grid standards. It also accommodates a broad voltage range (e.g., 200-230V and 380-460V), facilitating integration into equipment for diverse global markets.
