for low dew point dehumidifier requirement
Bry-Air, the leader in dehumidification…worldwide, with 60 years of experience in providing moisture control solutions for the most complex and critical industrial applications, helps support you with all your Battery Dry Rooms requirement under a single roof.
Bry-Air has the capability to build state-of-the-art Dry Rooms and provide complete solution for achieving low dew point control for your hygroscopic and moisture sensitive material processing.
Bry-Air Dry Rooms are equipped with patented Environment Control Dehumidification System, including refrigeration system. Bry-Air has proven success in meeting the stringent requirement of dew point lower than (-) 75℃ and has recently provided dry room solution to one of the most advanced and reputed Indian Defence Laboratories, Defence Research and Development Organization (DRDO). Bry-Air also takes pride in being the fastest growing adsorption technology group in the world and having over 141 patents applications filed in 15 new technologies of which 74 have been granted/ allowed already.
Dry Rooms are being used by pharmaceutical companies, automotives and selective other industries which have very low dew point requirements for their hygroscopic material processing and storage. Lithium and alternative battery manufacturers are today the most vulnerable and hence, are driving the high requirement for Dry Rooms. Every Dry Room is unique and there is a great amount of detailing and specialization requirement. Only few players who have the desired experience and subject knowledge are able to get the design and configurations of such units correct in the first instance. Safety is paramount in Dry Rooms, as a minor glitch or error may lead to major hazardous risks.
Bry-Air Airgineers are well trained and equipped to deliver any size of Dry Rooms, be it for use in research laboratories or large scale production areas. Our Airgineers develop turnkey dry room solutions ensuring highest standards of safety and design competencies. Working closely with the clients directly, they are able to design, install and retrofit some of the most advanced dry rooms with fully automated systems.

Don’t Let Moisture Reduce The Performance of Lithium Batteries
There are four critical legs on which the lithium battery production space stands on:
Bry-Air has the product and global standard technology for dry rooms.
The Green DryPurge (GDP) dehumidifier technology which is the most energy efficient dehumidifier for <1% RH dry rooms is patent of Bry-Air (Asia).
Bry-Air has the capability to build state-of-the-art Dry Rooms, and provide complete solution for achieving low dew point control for your hygroscopic and moisture sensitive material processing.
Bry-Air is the only total solution provider for dry rooms with environment control equipment incorporating patented technology critical for Lithium battery manufacturing.
In manufacturing of Lithium batteries there is a requirement of very low humidity conditions – typically below 1% RH or lower (- 35°C or -80°C dew point).
Also pure Lithium metal is extremely sensitive to even tiny amounts of moisture in the air in the lithium batteries processing rooms. Moisture sealed inside the battery can react after the battery is completed. When moisture in the air comes in contact with lithium metal, an exothermic chemical reaction occurs that forms Lithium Hydroxide and Hydrogen Gas.
2Li + 2H2O = 2LiOH + H2
So, in order to overcome above problems, dry rooms are used.
Green DryPurge® is covered by Patent Granted/Pending: USA, China, South Africa, India, South Korea, Japan, Canada, Mexico, Europe, Australia, Brazil.
Bry-Air installed state-of-art Dry Room, incorporating desiccant dehumidifier with patented technology, for lithium battery manufacturing at NSTL, Visakhapatnam for their underwater applications.
NSTL is located in the coastal area of Visakhapatnam where high moisture level in ambient air interrupts the performance and quality standards of underwater systems. The NSTL laboratory uses lithium based raw material, which is highly reactive to moisture, and requires controlled humidity typically less than 1% RH (-45°C dew point).
Bry-Air, the single source provider, built a fully integrated dry room incorporating desiccant dehumidifier with patented DryPurge® technology. The dry rooms made with metal clad polyurethane foam, modular type construction within an existing RCC building, included complete ducting, electrical wiring, cable routing for the equipment, lighting, antistatic flooring, construction of airlock rooms, PLC controls for operating dry room, housing for the dehumidifiers etc., was designed and executed by Bry-Air.
Bry-Air’s Green DryPurge® (GDP) technology is a patented technology that ensures optimum performance, even at ultra-low dew points of up to (-) 90°C. It is crucial for maintaining the required low humidity conditions (typically below 1% RH or lower) essential for lithium battery manufacturing.
Bry-Air emphasizes safety in Dry Rooms, given the potential hazards. The company’s Airgineers, well-trained professionals, develop turnkey dry room solutions with a focus on safety features. This includes specialized entry doors, proper lighting, air showers to limit dust ingress, and vapor-tight construction to ensure zero leakages.
The key constituents for Dry Rooms include insulated and fire-retardant modular panels, air-tight self-supporting rooms with HEPA filters, anti-static flooring, entrance doors with airlocks, and sensors such as controllers and dew point meters. Requirements include vapor-tight construction, proper insulation, and specific inner/outer skin materials like PPGI/SS/Powder coated.
Bry-Air’s Dry Room solution ensures that moisture levels are maintained below (-) 35°C dew point, crucial for lithium-ion battery manufacturing. Critical moisture control areas include battery assembly, glass to metal sealing, electrolyte filling, cathode production, testing, and electrode insertion.
