1. The system is equipped with a liquid filling pump and a gas filling pump. It does not need to be pressurized with nitrogen. The remaining gas in the raw material barrel can be directly returned to the manufacturer or recycled by yourself. This is a good energy saving and consumption reduction. measure.
2. The equipment has manual and automatic control systems. The filling valve adopts high-pressure pneumatic solenoid valve and realizes program automatic control through PLC. In addition, you can also manually operate each step individually for filling.
3. Filling steps: Place the bottle to be filled on the electronic scale and connect the pipeline, start the system - automatically perform the filling process - and sound and light alarm after filling is completed.
4. Recovery of gas phase heptafluoropropane: When the pressure in the raw material barrel is lower than the current normal value, start the gas phase pump. When the pressure is zero, it means that the gas has been pumped out and stop the pump.
