This Pakistan-based industrial refrigeration manufacturer specializes in cold storage and industrial cooling system production. As the business expanded into projects using ammonia (R717) and other challenging refrigerants, the company faced growing safety and operational challenges.

Traditional charging equipment lacked explosion-proof design and reliable material compatibility for corrosive and potentially hazardous working fluids like R717, R134a, and acetone. This created significant risks to worker safety, compliance with local safety regulations, and product consistency. The client urgently needed a robust, explosion-proof refrigerant charging solution that could handle multiple challenging refrigerants safely and accurately.

The client selected the Chunmu CM8600 Explosion-Proof Refrigerant Charging Machine, configured to meet their multi-refrigerant requirements:

• Supported Working Fluids: R717 (ammonia), R134a, and acetone
• Certifications: CE, ATEX, and ZJEx certified explosion-proof design
• Charging Speed: ≥40g/s (up to 80g/s depending on model configuration)
• Charging Accuracy: ±1g (for <100g fills) / ±0.3% (for >2000g fills)
• Core Features: Integrated evacuation, leak detection, and automatic charging; isolated electrical control system; explosion-proof vacuum pump
• Application: Industrial refrigeration system assembly, cold storage equipment, and special cooling system production

The CM8600(ExS)’s explosion-proof construction and versatile refrigerant compatibility made it the ideal choice for the client’s demanding operational environment.

1. Safety & Compliance for Hazardous Refrigerants

   Working with R717 (ammonia) and acetone introduces significant safety risks, including flammability and corrosiveness. The CM8600’s ATEX-compliant explosion-proof design, isolated electrical controls, and dedicated safety monitoring systems eliminated these risks. The machine helped the client meet strict local safety regulations, reducing workplace hazards and compliance concerns.

2. Multi-Refrigerant Compatibility & Operational Flexibility

   With support for all three required working fluids in a single unit, the CM8600 eliminated the need for separate charging equipment. The client can now seamlessly switch between R717, R134a, and acetone setups, streamlining production workflows and reducing downtime between different product lines.

3. Precision & Consistency for Industrial Cooling Systems

   The machine’s high-accuracy charging ensures consistent fill levels across all applications, even with varying refrigerant types and fill amounts. This eliminates product defects caused by overcharging or undercharging, improving the reliability and performance of the client’s industrial cooling systems and reducing costly rework.

After installation and commissioning, the CM8600 has been fully integrated into the client’s daily production operations. The equipment’s stable performance, robust safety features, and reliable multi-refrigerant handling have exceeded expectations.

The client’s engineering team shared: “The CM8600 has completely transformed our refrigerant charging process. We can now work safely with R717, R134a, and acetone with the precision and reliability we need for our industrial systems. The machine’s explosion-proof design gives us peace of mind, and its ease of use has made it an indispensable part of our production line. We are very satisfied with the performance and support from Chunmu.”

This successful deployment highlights Chunmu’s expertise in providing safe, reliable refrigerant charging solutions for challenging industrial applications worldwide.
