This moisture and humidity control technology is renewable without having to replace desiccant and is capable of reaching low humidity (20%RH or less) to ultra low humidity (5%RH or less) levels. Generally dry boxes with 5%RH or less is utilized in surface mount technology in order to comply with IPC/JEDEC J-STD-033.
Larger commercial units regenerate the sorbent by using hot air to remove moisture and expel humid air outside the room. An emerging class of membrane dehumidifiers, such as the ionic membrane dehumidifier, dispose of water as a vapor rather than liquid. These newer technologies may aim to address smaller system sizes or reach superior performance.
Moisture Removal Efficiency (MRE) is a measure of the energy efficiency of any dehumidification process. Moisture removal efficiency is the water vapor removed from air at a defined inlet air temperature and humidity, divided by the total energy consumed by the dehumidification equipment during the same time period, including all fan and pump ...
A properly installed and located hygrostat should be used to monitor and control humidity levels automatically, or a well-informed and conscientious human operator must constantly check for correct humidity levels. A humidity below 50% can prevent water condensation on building materials. [1] A dehumidifier can be used to balance the humidity.

[1] HMEs are one type of commercial humidification system, which also include non-heated-wire humidifiers and heated-wire humidifiers. [1] HMEs have been in clinical use for over 30 years. [2] An HME cassette plays a central part of lung rehabilitation after a total laryngectomy. [citation needed]
Compressed air dryers are special types of filter systems that are specifically designed to remove the water that is inherent in compressed air. The compression of air raises its temperature and concentrates atmospheric contaminants, primarily water vapor, as resulting in air with elevated temperature and 100% relative humidity.
Vacuum drying is the mass transfer operation in which the moisture present in a substance, usually a wet solid, is removed by means of creating a vacuum.. In chemical processing industries like food processing, pharmacology, agriculture, and textiles, drying is an essential unit operation to remove moisture. [1]
