Bry-Air Low Dew Point (LDP) Dehumidifier 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) can control moisture levels from-40°C to -80°C supply air dew point in a dry room 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 a 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 gigafactories 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 for any multi fold growth which the battery cell manufacturing industry is yet to witness.

What is the ideal environment needed for Li-Battery Production?

Lithium battery cell production is undertaken in a very critical and controlled (dry room) environment conditions. Non maintenance of the desired RH during Li-ion cell manufacturing (<1%) and battery assembling (<10%) may lead to consequences such as:

  • Degradation in power storage characteristics of Lithium
  • Reduced performance and battery life
  • Explosion in batteries in extreme cases

We understand the core technology and know how to implement it

  • Our patented Honeycomb Desiccant Rotors are pH neutral & inert to gases such as Hydrogen Fluoride (HF) generated during the production of Li-batteries
  • Largest & Own Rotor manufacturing, no dependence on any overseas supplier
  • >50 OEMs globally, and nearly 7 of the top 10 leading manufacturers have been sourcing the rotors from them
  • Patented technology for the most energy efficient <1% RH low dew point jobs; no post cooling coil requirement
  • Customised engineered systems having highest CFM/sq. ft. floor area thereby saving huge real estate costs; robust & durable, >20 years life
  • Having capability of shipping fully integrated & tested single piece dehumidifier units
  • Vapour tight construction for Zero leak
  • Anti-static floor
  • Insulated modular PUF prefab panels (fire retardant – optional)
  • PPGI or stainless steel interior and exterior sheet protection for panel
  • Ante/Air lock room
  • Lighting (400 lux level)
  • Duct work with proper insulation
  • PLC based control, dew point sensor
