What should be considered first when deciding between open and closed drying systems?

When determining whether to utilize open or closed drying systems, the outside air humidity ratio plays a pivotal role. This factor significantly influences the effectiveness of the drying process. In an open drying system, outside air is introduced into the space to facilitate moisture removal. However, if the outside air is excessively humid, it may counteract the drying efforts by introducing more moisture into the environment.

Conversely, a closed drying system relies on dehumidification, recirculating the indoor air while extracting moisture humidity levels are lower, making it more efficient. Therefore, assessing the outside air humidity ratio is crucial because it directly impacts the choice between using open or closed systems, ensuring the water damage restoration process is optimized for speed and effectiveness. Taking this into account allows restoration professionals to make informed decisions that will enhance the drying efficiency and overall outcome of the restoration efforts.
