−70°C dew point N₂ inerting for lithium battery production. PSA + catalytic gas purifier combo prevents moisture-related defects in cell assembly and electrolyte filling.
PSA + catalytic purifier achieves −70°C dew point at point-of-use. Classifies as ISO Class 0 dry room environment for lithium battery production.
N₂ inerting prevents moisture reaction with lithium electrodes and electrolyte. Reduces battery defect rate from 5% to <0.5% in cell assembly areas.
N₂ dry room consumes 40% less energy than conventional desiccant wheel systems. Smaller HVAC load, lower electricity costs, simpler maintenance.
Automatic dew point monitoring and alarm. N₂ flow adjusts automatically based on room humidity sensors. No humidity spikes during shift changes.
PSA produces 99.99% N₂
