High Accuracy Automatic Refrigerant Charging Machine in the Rail Transit Industry

CRRC Qingdao Sifang Rolling Stock Research Institute Co.,Ltd mainly engages in manufacturing of rail transit, and their main business scope covers rail transit special equipment, core systems and components sales; high-speed rail equipment and accessories sales; R&D for mechanical equipment; high-speed rail equipment and spare parts producing and sales; Auto parts and accessories producing; wind turbine generating systems and accessories manufacturing; generator and its spare parts selling; wind power generating technology service; industrial automatic control system manufacturing, etc.

Due to the following client’s on-site condition, we recommend them our CM8600 series high speed accuracy refrigerant charging machine:

On-site application: uses in laboratory, to fill refrigerant into electrical of high-speed rail

Refrigerant types: R134a/R245fa/R22/R513A/R404A/R410A,etc

Single charging amount per each refrigeration units: 0.1-50kg

Required filling accuracy: ≤0.5% for 0.5-2kg; ≤0.3% for above 2kg

Required resolution: ＜1g

Vacuum rate: ≥5L/S

Vacuum pressure: ≤10Pa

Power supply: 220V50Hz

Charging amount:20-30kg

Our CM8600 series refrigerant charging machine integrates the function of vacuum, leak detection and automatic charging, also our refrigerant charging machine has the more features as follows

1) it has wide charging ranges from 10g-9999999g can satisfy different clients’ demands.

2) It adopts high speed charging gun technology and optimized booster pump technology to provide stable technical support for high speed refrigerant charging machine, so the single charging amount can reach 999kg

3) With intelligent linear algorithm technology to ensure the accuracy of each charging point not the accuracy of designated points.
4) Also has whole-day real time temperature compensation function to make sure the charging accuracy under the different temperature, no need for frequent calibration, save time and labor cost.
5) we have own laboratory, in which we can do out factory lab by simulating temperature from -10℃~50℃ when we finish production, to guarantee the accuracy of each temperature point and the stable charging performance, otherwise the accuracy and stability of refrigerant charging machine can not be guaranteed totally.
  The automatic high accuracy refrigerant charging machine applies different industries such as air conditioning of rain transit, water dispenser, coffee machine, beer machine, frozen cabinet, heat pump,etc.

Our refrigerant charging machine has passed CE certificate, also has been exported to Spain, the United States, France, Switzerland, Mexico, Tunisia and other 35 countries and regions around the world.
