01 / WORKING ENVIRONMENT
Protect sensitive processes
The sealed gas purification system removes H₂O and O₂ from the chamber to maintain an inert atmosphere. The specified moisture and oxygen concentrations are ≤ 0.1 ppm.
02 / OPERATING PRINCIPLE
Purify. Recirculate. Regenerate.
Recirculating gas purification and a regenerable purification column maintain low moisture and oxygen levels.
Structure & Operating Principle
The 3GBS consists of a sealed main chamber, large and small evacuable antechambers, a rotary vane vacuum pump, and a display with a PLC controller.
The gas purification system combines a single automatically regenerable purification column with a circulation blower to purify and maintain the working environment. The system is designed to establish an inert atmosphere with H₂O and O₂ levels of ≤ 0.1 ppm.
