A company specializing in automotive tech R&D and component sales has enhanced its lab refrigerant workflows by adopting ChunMu’s CM8600(ExS) Flammable Refrigerant Charging Machine and CM-V400 Oil-free Explosion Proof Refrigerant Recovery Machine—tailored solutions for its lab’s strict safety and precision needs.

The firm’s lab focuses on testing automotive HVAC systems and refrigerants (e.g., R290, R32, R1234YF)—and faced two critical pain points:

• Precision for Lab Testing:
  Existing equipment couldn’t meet the ±1g accuracy required for consistent, reliable refrigerant performance data.
• Safety for Flammable Refrigerants:
  Lab environments demand explosion-proof compliance (ATEX/CE) to handle high-risk refrigerants safely.

ChunMu’s CM8600(ExS) and CM-V400 were designed to align with these lab-specific requirements.

The CM8600(ExS) Refrigerant Charging Machine is ideal for the lab’s controlled testing scenarios:

• Lab-Grade Accuracy:
  Delivers ±1g precision (for doses <100g) via RRT turbine flowmeters, ensuring test data consistency for automotive HVAC prototypes.
• All-in-One Workflow:
  Integrates vacuum pumping, leak detection, and auto-charging—streamlining lab setup for repeated refrigerant testing cycles.
• Certified Safety:
  CE, ATEX, and ZEx certifications meet the lab’s explosion-proof standards for flammable refrigerant handling.

The CM-V400 Recovery Machine supports the lab’s sustainable, compliant refrigerant reuse:

• Lab-Safe Design:
  ATEX-certified, oil-free 4HP compressor eliminates contamination risks—critical for preserving refrigerant purity in repeated tests.
• Thorough, Auto-Shutoff Recovery:
  Automatically stops at -0.04Mpa to ensure complete refrigerant retrieval from test units, reducing waste in the lab.
• High Compatibility:
  Handles multiple refrigerants (R290/R32/R1234YF) without cross-contamination, matching the lab’s diverse testing portfolio.

By pairing the CM8600(ExS) (for precise lab charging) and CM-V400 (for safe lab recovery), the firm has streamlined its refrigerant testing workflows: reducing manual errors, ensuring compliance with lab safety protocols, and improving the reliability of its automotive HVAC R&D data.
