Clean cold rooms are designed to maintain exceptionally low levels of particulates, such as dust, airborne microorganisms, and vaporized particles, while maintaining precisely controlling temperature and relative humidity (RH). These environments are essential for specialized production, scientific research, and precision manufacturing.
