Fully Automatic Glove Box ZKYQX-I Gas Purification and Circulation System

One. Glove Box Function

Sealed Recirculation

The inert gas within the glove box is circulated and purified through a closed loop by a recirculating fan and purifier, continuously removing moisture and oxygen.

Automatic Control Regeneration

Deoxygenation materials can be regenerated, with the regeneration process controlled by a program.

Cabinet Pressure Control

The glove box's internal pressure is automatically controlled by a PLC. The working pressure can be freely set within +/- 1500Pa, and the system automatically protects against deviations beyond +/- 1500Pa.

Vacuum pump automatic control

Vacuum pumps are required to automatically activate when needed in the system.
