As a professional manufacturer in the air conditioning industry, Suzhou Linsay Thermal Technology Co., Ltd. continuously focuses on improving production efficiency and charging accuracy. To support its expanding production requirements, the company recently introduced the ChunMu CM8600 Refrigerant Charging Machine Professional Edition into its manufacturing line.

Customer Industry

Industry: Air Conditioning Manufacturing

Refrigerants Used

• R410A
• R134a
• R407C

Customer Challenges

Before adopting the CM8600, Suzhou Linsay had been operating a refrigerant charging machine from another brand together with the ChunMu CM301 Vacuum Pre-Evacuation Machine. The existing setup had been running reliably for years.

However, as production diversified, several challenges emerged:

• Multiple refrigerants required frequent switching during production.
• Refrigerant changeovers became increasingly time-consuming and inconvenient.
• The existing charging machine had been in service for many years, resulting in reduced charging accuracy after repeated refrigerant conversions.
• Growing production demands required an additional charging solution capable of supporting future expansion.

The company needed a more advanced charging system that could maintain precision, improve operational convenience, and adapt to future production upgrades.

ChunMu Solution: CM8600 Refrigerant Charging Machine Professional Edition

To address these requirements, ChunMu recommended the CM8600 Professional Edition, designed specifically for manufacturers seeking higher efficiency and greater flexibility.

Key Advantages

1. Dual-Piston Hardware for Higher Capacity

Compared with the standard version, the Professional Edition features two additional piston systems, enabling faster charging performance. Even if future products require larger refrigerant charge volumes, the machine can easily handle increased demands.

2. Faster Calibration Across the Full Charging Range

The CM8600 Professional Edition significantly simplifies calibration procedures. Operators only need to perform two charging cycles to establish the complete charging range.

In contrast, conventional systems often require multiple calibration shots to cover the entire charging spectrum, increasing setup time and reducing productivity.

3. Stable Performance Under Temperature Variations

Temperature fluctuations can affect refrigerant saturation pressure. On standard charging machines, operators may need to manually adjust gas valve pressure to prevent abnormal boosting conditions.

The CM8600 Professional Edition eliminates this issue through its dual-piston alternating charging technology. Since charging pressure remains constant—typically 5 to 6 times the air supply pressure—the system maintains stable operation without additional pressure adjustments.

Results

By implementing the ChunMu CM8600 Refrigerant Charging Machine Professional Edition, Suzhou Linsay Thermal Technology has gained:

• Improved charging accuracy across different refrigerants
• Reduced downtime caused by refrigerant switching
• Faster calibration and setup processes
• Greater operational convenience for production personnel
• Enhanced capability to support future increases in charging volume

For air conditioning manufacturers handling multiple refrigerants, choosing a charging solution that combines precision, flexibility, and scalability is essential. The ChunMu CM8600 Professional Edition delivers exactly that—helping customers optimize production today while preparing for tomorrow's manufacturing challenges.

ChunMu Refrigeration remains committed to providing intelligent refrigerant charging solutions that improve efficiency, accuracy, and long-term value for customers worldwide.
