A professional cabinet air conditioner manufacturer encountered prominent production bottlenecks on its assembly line. The workshop produces two core cabinet AC models with fixed refrigerant filling volumes: 1kg and 3kg per unit, requiring stable charging for R134a, R407C and R410A.

Their old charging equipment featured narrow adjustable filling range, poor accuracy between 1kg and 3kg specification, no automatic warning for low refrigerant supply, and lacked scheduled maintenance reminders, triggering frequent downtime, inconsistent filling volume and excessive refrigerant waste. Meanwhile, incomplete pre-evacuation became another defect source, pushing the client to source integrated charging + vacuum pre-evacuation solutions: one set of CM8600 refrigerant charging machine plus four CM-VP automatic vacuum pre-evacuation units.

• Wide continuous charging range 10~9999999g, fully covers 1kg and 3kg filling requirement, reserves surplus range for future new product without equipment upgrade.
• Intelligent linear algorithm ensures consistent high precision across full weight span for both 1kg & 3kg cabinet AC filling.
• Auto-alarm system triggers prompt once refrigerant cylinder runs low on liquid, avoiding abnormal under-filled products.
• Customizable scheduled maintenance reminder function guides regular equipment upkeep to cut unexpected breakdown.
• Optional built-in refrigerant recovery module effectively cuts unnecessary refrigerant loss and running cost.

• 1. Wide filling range avoids future equipment upgrade cost The ultra-wide 10~9999999g charging span perfectly matches existing 1kg and 3kg cabinet AC production, and reserves enough capacity for upcoming new-spec cabinet air conditioner projects. Client saves large capital spent on later equipment replacement or modification.
• 2. Full-range precision eliminates unqualified products Relying on intelligent function linear algorithm, CM8600 keeps stable filling accuracy on both 1kg small-volume and 3kg large-volume working condition, drastically reducing defective AC units caused by overcharge or insufficient refrigerant.
• 3. Intelligent warning design minimizes unexpected production halt Auto reminder for insufficient cylinder refrigerant prevents sudden half-way charging failure; timed maintenance alert helps workshop arrange routine servicing during off-production hours, cutting unplanned line downtime obviously.
• 4. Built-in recovery reduces long-term refrigerant expenditure Integrated refrigerant recovery option collects leftover medium during commissioning and test, curbing raw refrigerant waste and lowering monthly material cost.

Besides, matched four CM-VP vacuum pre-evacuation machines finish deep evacuation before charging, removing residual air and moisture inside cabinet AC loop, further improving finished product cooling performance and reducing after-sales failure rate.

After commissioning and months of full-load running on cabinet AC production line, the client gives positive evaluation: “Chunmu CM8600 solves all our past filling troubles. The wide filling range saves our future upgrade budget, stable precision makes reject rate drop sharply, and multiple intelligent reminder functions greatly simplify our daily workshop management. Matched four vacuum pre-evac units perfectly coordinate with charging process. We are fully satisfied with overall machine performance and plan to purchase extra identical units for our second production line expansion.”
