Adopting screw or piston compressors, some models combine magnetic levitation technology to reduce friction losses and adapt to the wide temperature range of -40 ℃ to -160 ℃. Prioritize the use of natural refrigerants (such as ammonia/NH3, carbon dioxide/CO ₂) and low GWP synthetic refrigerants, in compliance with global environmental regulations (such as EU F-Gas). Equipped with PLC+IoT remote monitoring system, supporting adaptive adjustment, fault warning and energy efficiency analysis, reducing operation and maintenance costs. Flexible combination of unit capacity, easy to expand and upgrade, suitable for different scale requirements.
