Hisense Tianrui Maglev Intelligent Technology focuses on the R&D and production of high-performance maglev refrigeration equipment. Its production workshop involves frequent recycling and refilling of flammable refrigerants such as R32, R290 and R1234ze. These high-risk refrigerants put forward strict explosion-proof standards for all supporting process equipment. Traditional recovery equipment carries hidden risks of oil contamination and insufficient safety protection, which cannot match the company’s strict production safety and product quality standards. To standardize the refrigerant processing procedure, the enterprise introduced the ChunMu CM-V400 oil-free explosion-proof refrigerant recovery machine.

The CM-V400 offers robust features for demanding industrial environments:

• Equipped with a 4HP dedicated oil-free compressor, supporting cross-recovery of multiple refrigerants without medium pollution.
• Adopts a reversing valve structure, allowing free switching between gas recovery and push-pull liquid recovery without pipeline replacement, greatly simplifying workshop operation steps.
• The device automatically stops working when the suction pressure reaches -0.04MPa to guarantee thorough refrigerant recycling.
• Built-in oil separators and filters effectively remove frozen oil, moisture and sundries inside refrigerants to guarantee clean recovered media.
• The whole machine is built in full compliance with explosion-proof specifications and holds CE and ATEX authoritative certifications, fully fitting the safety management requirements of Hisense’s production site.
• Its liquid push-pull recovery speed reaches 1300kg/h, meeting the batch production rhythm of maglev units steadily.

After deploying the CM-V400, Hisense Tianrui Maglev achieves safer, cleaner and more efficient refrigerant recovery and filling work. It cuts hidden safety hazards in the production line, improves the reutilization rate of refrigerants, and supports stable, standardized mass manufacturing of maglev refrigeration products.
