Precision dry rooms for semiconductor and battery production.
A dry room is a specialized controlled environment designed to maintain extremely low moisture levels in the air. It is essential for the manufacturing and research of humidity-sensitive products. While conventional cleanrooms focus on controlling airborne particles, dry rooms are primarily designed to regulate dew point, which is the critical factor in moisture control.
Key Principles and Features
Dry rooms maintain ultra-low humidity conditions with dew points ranging from -40°C to -70°C (typically below 0.5% relative humidity). - Dehumidification System Desiccant dehumidifiers are commonly used. A rotating wheel coated with moisture-absorbing materials such as silica gel or zeolite captures moisture from the air and is continuously regenerated using heated air. - Airtight Structure Walls and floors are specially sealed to prevent external moisture ingress, and entry points are equipped with airlock systems to maintain environmental stability.

Key Applications
Dry rooms are critical in advanced industries where exposure to moisture can degrade performance or cause safety risks. - Lithium-ion Battery Manufacturing Lithium reacts with moisture, potentially causing gas generation, reduced battery life, or even explosion. Dry rooms are used across electrode processing, assembly, and electrolyte filling. - Next-Generation Energy (e.g., Solid-State Batteries) These technologies require even lower dew points due to higher sensitivity of solid electrolytes to moisture. - Pharmaceuticals & Biotechnology Used for producing and packaging moisture-sensitive powders, capsules, and diagnostic kits to ensure product stability and shelf life. - Defense & Aerospace Prevents corrosion and maintains precision during the assembly of missiles, guided systems, and satellite components. - Specialty Chemicals Applied in processes involving adhesives, coatings, and semiconductor chemicals that react with moisture.
