Humidity control is critical in battery dry rooms as various materials and processes used in battery production are susceptible to moisture damage.
A low dewpoint air supply will mitigate the risks by creating a stable production environment suitable for the materials and processes. But what is a dry room? And how can the low dewpoint be sustained?
This article examines these questions and looks to provide the answers.
What is a dry room?
A dry room is a specialist production area that uses industrial dehumidification systems to maintain the air within the controlled space at low dewpoints (dp). Controlling humidity allows manufacturing processes or research primarily using hygroscopic (moisture-sensitive) materials.
Typically, in a dry room, the air is maintained at or below minus 30.0°Cdp, equivalent to less than 1% relative humidity (RH) at a typical room temperature of 22.0°C dry bulb (db).
