For companies working with flammable and explosive refrigerants such as R290, R600a, R32, R1234ze, and R1234yf, selecting a safe, certified, and efficient recovery and charging solution is essential. Nanjing Jiuding recently introduced one unit of the CM-V400 series explosion-proof refrigerant recovery machine, manufactured by ChunMu Refrigeration, to support its large-scale handling of hydrocarbon refrigerants. According to customer feedback, the equipment has performed exceptionally well, delivering both operational efficiency and enhanced safety.

The CM-V400 series explosion-proof refrigerant recovery machine is designed specifically for medium- and large-size refrigerant systems that require fast, clean, and reliable recovery. The unit is equipped with a 4HP high-power, oil-free compressor designed exclusively for refrigerant recovery applications. This oil-free configuration ensures stable performance, eliminates risks associated with lubricant contamination, and increases long-term reliability—an especially important advantage for hydrocarbon refrigerant processing.

Another core strength of the system is its ability to recover multiple refrigerants in cross-application scenarios without causing contamination. This capability is highly valued by customers like Nanjing Jiuding, whose operations may involve several refrigerant types. The integrated reversing-valve design allows operators to perform both gas recovery and push-pull liquid recovery without switching pipelines, significantly reducing downtime and simplifying daily workflows. This design innovation has become one of the most recognized advantages of the CM-V400 series explosion-proof refrigerant recovery machine.

Safety remains a top priority in ChunMu’s engineering philosophy. The CM-V400 system incorporates comprehensive protection mechanisms that ensure stable operation even under demanding conditions. The machine completes the recovery process when the suction pressure reaches –0.04 MPa and shuts down automatically, preventing over-operation and enhancing equipment longevity. In addition, the system comes standard with an oil separator and filter to remove refrigerant impurities, moisture, and residual oil, ensuring cleaner refrigerant and more reliable downstream use.

Every unit in the CM-V400 series explosion-proof refrigerant recovery machine is manufactured strictly in accordance with explosion-proof requirements. The product has passed EU CE certification and ATEX explosion-proof certification, demonstrating compliance with international safety standards. These certifications are key reasons why many European and global customers trust ChunMu equipment for flammable refrigerant handling.

By adopting the CM-V400 system, Nanjing Jiuding has significantly enhanced its refrigerant recovery efficiency, improved safety assurance, and reduced risks often associated with hydrocarbon refrigerant operations. The customer reported high satisfaction with the stability, speed, and safety of the equipment, reinforcing ChunMu’s reputation as a reliable supplier in the refrigerant recovery sector.

In conclusion, the CM-V400 series explosion-proof refrigerant recovery machine represents a robust solution for enterprises requiring high-efficiency and high-safety refrigerant recovery equipment. With advanced oil-free compression technology, convenient switching design, strong purification functions, and internationally recognized explosion-proof certification, ChunMu continues to support customers in achieving safer, greener, and more efficient refrigerant management.
