 Green DryPurge® Dehumidifier – GDP Series


Bry-Air engineered dehumidifiers maintain stringent Dry Room conditions for Lithium-battery processing. The Green DryPurge® (GDP) dehumidifier from Bry-Air is the most efficient and economical solution to provide dry air required for Lithium-battery production. These engineered dehumidifiers are specially designed to control moisture levels in the lithium-battery manufacturing areas from -40°C to -70°C dew point depending on the process being carried out.
drypurge_diagramLithium-battery processing generates hydrofluoric acid which is carried into the return air (4-6 ppm) damaging the dehumidification media and resulting in 30-50% weight loss in dehumidification capability. However, the heart of the Green DryPurge (GDP) dehumidifier from Bry-Air is the EcoDry Desiccant Honeycomb Rotor which has excellent tolerance to hydrogen flouride, does not deteriorate easily and hence, does not require frequent replacement. The average life of the EcoDry Rotor is 5 years.
