Suzhou Linsay Thermal Co., Ltd. Upgrades AC Production with ChunMu CM8600 Refrigerant Charging Machine
Suzhou Linsay Thermal Technology Co., Ltd. is a professional manufacturer engaged in air conditioner production. For a long time, the workshop has been running a complete refrigerant processing workflow with an third-party refrigerant charging machine and one set of ChunMu CM-VP601 automatic vacuum pre-evacuation unit. The existing CM-VP301 vacuum device delivers steady performance and fully meets the factory’s vacuuming demands.
However, the aging third-party charging machine has gradually exposed prominent drawbacks amid daily mass production. The factory needs to frequently switch among three mainstream refrigerants: R410A, R134a and R407C. Frequent refrigerant replacement brings complicated manual operations and lengthy conversion time. Worse still, the ageing equipment suffers from drifting charging accuracy after each switch, leading to unqualified products and unstable production quality. To resolve these long-standing pain points and expand production capacity, the company decided to add a new high-performance refrigerant charging machine and finally chose the professional version ChunMu CM8600 Refrigerant Charging Machine.
Delivered Solution & Core Advantages
The factory deployed the professional-grade ChunMu CM8600 Refrigerant Charging Machine to work alongside the existing ChunMu CM-VP601 vacuum pre-evacuation unit, serving the mixed production of R410A, R134a and R407C. This upgraded model is equipped with dual cylinder pushing hardware and optimized control logic, bringing three major advantages over ordinary charging machines: Higher charging speed & strong expandability
The additional two sets of cylinder pushing hardware greatly accelerate the overall charging speed and improve line throughput. Meanwhile, the enhanced structure can cope with larger refrigerant filling volumes for future product upgrades, eliminating the need for secondary equipment renovation.
Ultra-fast full-range calibration
Different from ordinary models that require multiple test shots to complete full-range calibration, this professional version only needs two test shots to finish calibration across the entire charging range. It drastically shortens the preparation time after refrigerant switching and simplifies daily operation.
Constant charging pressure against temperature changes
Refrigerant saturated pressure fluctuates obviously with ambient temperature changes. Ordinary machines require manual air valve pressure adjustment to avoid abnormal pressurization errors under extreme temperature conditions. Benefiting from the dual alternating cylinder pushing design, CM8600 refrigerant charging machine maintains a stable charging pressure at 5-6 times the air source pressure all the time. It adapts to large temperature differences on site and completely removes the trouble of frequent pressure regulation.
Solved Customer Pain Points
1. Complicated operation & low efficiency of refrigerant switching
The optimized program and fast calibration function of CM8600 refrigerant filling machinesimplify the switching process between R410A, R134a and R407C. The workshop no longer spends plenty of time on repeated debugging, which significantly improves production line efficiency.
2. Poor charging accuracy after refrigerant replacement
Relying on precise calibration and stable pressure output, the new machine keeps excellent filling accuracy even after frequent refrigerant switching, effectively cutting defective products caused by inaccurate charging.
3. Troublesome pressure adjustment under temperature variation
The constant pressure output realized by dual cylinder pushing adapts to complex on-site temperature environments. The maintenance team no longer needs to adjust air valve pressure repeatedly, reducing manual intervention and potential operational errors.
4. Hidden risks for future production upgrade
The dual cylinder pushing structure supports larger charging volume demands, reserving sufficient performance space for the company’s subsequent new air conditioner projects.
Customer Feedback
After installation, commissioning and formal operation, the ChunMu Refrigerant Charging Machine has perfectly coordinated with the original CM-VP301 vacuum pre-evacuation unit. The production supervisor of Suzhou Linsay Thermal Technology commented:
“We are deeply impressed by the performance of ChunMu CM8600 charging machine. It solves all the problems of our old charging equipment. Fast calibration makes refrigerant switching much easier, and the constant pressure design saves us a lot of daily adjustment work. The charging accuracy stays stable all the time. With faster charging speed and expandable performance, this machine fully meets our current production and future upgrade needs. We are very satisfied with this purchase.”
