A dry room is a controlled environment designed to maintain extremely low humidity levels, as required in the lithium-ion battery manufacturing, pharmaceuticals, and electronics. This room use an advanced dehumidification systems, including desiccant-based drying and HVAC control, to achieve ultra-low dew points (as low as -40°C). Key capabilities of dry rooms include precise humidity and temperature regulation, contamination control, and energy-efficient air handling to ensure product integrity and safety. They are critical for processes sensitive to moisture, such as electrode coating, electrolyte handling, and semiconductor fabrication, where even trace amounts of moisture can degrade performance and longevity.
