DH系列低温高压冷媒充注机，可充注R170、R23、R23、R13、R508b、R744等冷媒。超低温制冷剂

的制冷温度可达-80℃以下，超低温冷媒由于临界温度低，其充注模式与常规冷媒不同，充注精度约为

100g≤±1g ，已经极大的提升了充注精度。主要用于：环境试验箱、超低温冷柜、血库冰箱、热管、鱼灯散热

、通讯技术、太阳花、芯片散热、基站热交换、HR热能效应等

Ultra low temperature double gun refrigerant filling machine

DH series low temperature and high pressure refrigerant filling machine can fill R170, R23, R23, R13, r508b, R744 and other refrigerants. Ultra low temperature refrigerantThe refrigeration temperature can reach below - 80 ℃. Due to the low critical temperature, the charging mode of ultra-low temperature refrigerant is different from that of conventional refrigerant, and the charging accuracy is about100g ≤± 1g, which has greatly improved the filling accuracy. It is mainly used for heat dissipation of environmental test box, ultra-low temperature freezer, blood bank refrigerator, heat pipe and fish lamp, communication technology, solar flower, chip heat dissipation, base station heat exchange, HR heat effect, etc
