CACL-788C- T4 series double system refrigerant charging machine has been design to charge R134a, R22, R404A, R410A or other HCFC, HFC refrigerants and to be used in any type of cooling unit assembly line (water dispenser, refrigerator, freezer, heat pump etc.) performing evacuation, leak tests and refrigerant charges. Thanks to double charging system design (double IDB balance cylinder, double CA-5AG charging gun, double pneumatic booster pump and double flowmeter), T4 series achieve dual refrigerant charging online, greatly improved the production efficiency. The fastest charging speed is 120g/s, the biggest charging volume is 9999g (Extensible), and the charging precision is 100g ≤±0.5g, 100g outside ≤±0.5%.R513a、R22、R404A、 R406A、R410A等HCFC、HFC系列主流冷媒，适用于饮水机、电冰箱、冷柜、热泵等各类制冷机的冷媒充注。T4系列配备双路充注系统（双路 IDB智能双级平衡缸、双路CA-5AG后导顶杆充注枪、双路纯气动高效增压泵、双路红宝石流量计），实现了双冷媒的在线充注，极大地提升了生产效率，满足混线生产需求。
