4 Port Double Station Glove Box

Function

• Closed loop

The inert gas in the glove box is circulated in a closed loop by the circulating fan and purifier to continuously remove water and oxygen

• Automatic control of regeneration

The water and oxygen removal materials can be regenerated, and the regeneration process is controlled by the program

• Automatic cleaning

The atmosphere replacement in the glove box is completed by an automatically controlled cleaning valve

• Cabinet pressure control

The pressure in the glove box is automatically controlled by PLC, which can be set freely, if it exceeds +/- 16mbar, the system will automatically protect it.

• Automatic control of vacuum pump

The vacuum pump is required to be automatically turned on when the system needs it

‍

• Gas purification circulating system

◦ Purification column

Function: gas seal, water removal, oxygen removal Container material: 304 stainless steel

Purification material: copper catalyst: 4.8 kg; molecular sieve: 4.8 kg

Purification capacity: oxygen removal: 60L; water removal: 2Kg Water and oxygen index: less than 1ppm

◦ Circulation system

Working gas: nitrogen, argon, helium

Circulation capacity: integrated fan flow 90m³/h, variable frequency, it can adjust the fan flow according to the water and oxygen content.

◦ Regeneration

Operation: PLC automatically controls the regeneration process

Regeneration gas: working gas mixed with hydrogen (hydrogen 5-10%)

◦ Valve

Main valve: DN 40 KF, electropneumatic angle valve

Control valve: solenoid integrated valve, reduce leakage rate

‍

• Control system:

◦ Function: including self-diagnosis, power-off and self-starting features, with pressure control and adaptive functions; automatic control, cycle control, password protection, unit control adopts SIEMENS PLC touch screen

◦ Pressure control: The working pressure of the control box and transition bin can be set freely within +/- 15mbar, and the system will automatically protect if it exceeds +/- 16mbar;

◦ Foot pedal: Control the pressure of the box body, convenient to operate the pressure increase and decrease

‍

• Display system:

SIEMENS PLC touch screen smart 700 is used to display operating status, box pressure, system records, etc.

• Control of vacuum system

UK EDWARDS vacuum pump, type:RV12, which can be started manually or through PLC, with a flow of 12m³/h, which can vacuum the transition bin and maintain the pressure balance of the box body. The ultimate acuum of the vacuum pump is less than or equal to 2x10-1pa.

• Oxygen Analyzer

Measuring range: 0~1000ppm

The use of ZrO2 sensor avoids the problem that the fuel cell has a short life and cannot be exposed to the air.

• Moisture Analyzer

Measuring range: 0~500ppm

It has a wide range of applications, especially for users in lithium battery manufacturing and metal-organic fields, it can be restored to the original state through the cleaning and regeneration process, avoiding the problem of crapping after one pollution

• Organic solvent absorber

Dimension: diameter 238 mm, height 407 mm, filled with 7.3 kg absorption material, Placed under the box, connected with the main circulation pipeline, the circulating gas can first flow through the organic solvent adsorber device to absorb the organic solvent in the gas and with internal solvent trap (1.25KG Absorbent Activated carbon).
