Low Dew Point (LDP) Dehumidifiers

Bry-Air Low Dew Point (LDP) Dehumidifiers is the ideal solution for battery cell manufacturing. They are the perfect solution for moisture menace in your high demand Dry Rooms, critical for lithium battery manufacturing.

These high energy saving, customized environmental control equipment – Low Dew Point Dehumidifiers (LDP) along with Dry Rooms can control moisture levels from-40°C to -80°C dew point depending on the hygroscopic material processing being carried out. Tailored exclusively for Lithium Battery manufacturing and embedded with Patented Technology, the LDP from Bry-Air is the most energy efficient dehumidifier for <1% RH dry rooms.

The Super LDP & Green DryPurge (GDP) dehumidifiers are specially designed and engineered to control moisture levels and have the shortest manufacturing lead time vis-a-vis any competitor product available in the world. The equipment is manufactured under the modular approach leading to ease in transportation, faster dispatch and better inventory management.  Assembling on site is far simpler due to the extensive years of R&D put behind making some of the best low dew point desiccant dehumidifiers installed and functioning smoothly across the globe.

Ours is the largest dedicated manufacturing facility in the world for special lithium-ion cell manufacturing dehumidifiers. We have an actual working dry room at one of our facilities in Gurugram, India and dedicated lab for testing low dew point desiccant unit configurations.

We are modest and well equipped in our efforts to support our country and the world with the best air handling units for giga factories mushrooming across the globe for making the environment green and healthier, be it electric vehicles or energy storage systems compensating for the depleting natural resources. Our processes, plants and people are ready to for any multi fold growth which the battery cell manufacturing industry is yet to witness.
