Liquid carbon dioxide small steel cylinder filling equipment, gas cylinder filling system, automatic filling machine
1、 Equipment principle
The automatic filling machine is suitable for filling small bottles such as 0.5L/1L/2L and various gas cylinders
Digital pressure control: High pressure upper limit pressure and low pressure lower limit pressure can be set to achieve the purpose of automatic start below the lower limit pressure and automatic stop above the upper limit pressure, which is commonly known as high stop and bottom start.
2、 Scope of application
Low temperature CO2 pressurized transportation, high-pressure filling of small gas bottles, and recovery and use of liquid carbon dioxide
Carbon dioxide, nitrous oxide, refrigerant (Freon), etc
