Desiccant Dehumidifiers
Desiccant Dehumidifiers.
Desiccant dehumidifiers utilize chemical attraction instead of condensation to remove water from the air. Because they are not limited by low dew point temperatures and when used properly they produce the lowest vapor pressure of any dehumidifier.
Desiccant dehumidifiers have many applications in restorative drying, but they are most commonly used to dry dense materials such as hardwood floor.
Desiccants do not collect water in a pan for automatic pump-out instead , they produce damp reactivation air, which must be vented outside the structure using temporary ducting. In some situations this venting results in a pressure differential in the drying area.

Cat 3 water loss
Category 3 water loss
Category 3 water loss is grossly contaminated and can contain pathogenic, toxigenic or other harmful agents. Examples of category 3 water sources can include, but are not limited to: sewage; toilet back flows that originate from beyond the toilet trap regardless of visible content or color; and other contaminated water entering or affecting the indoor environment, such as wind-driven rain from hurricanes, tropical storms, or other weather-related events. Such water sources may carry silt, organic matter, pesticides, heavy metals, regulated materials, or toxic organic substances.
This is the highest level of contamination. Precautions to protect workers and building occupants must be taken. These may include the use of Personal Protective Equipment (PPE) and/or Air filtration devices (AFD) with HEPA (High Efficiency Particulate Air) filters

CAT 2 water loss
Category 2 water loss
Category 2 water contains significant contamination and has the potential to cause discomfort or sickness if contacted or consumed by humans. Category 2 water can contain potentially unsafe levels of microorganisms or nutrients for microorganisms, as well as other organic or inorganic matter ( chemical or biological)

Category one Water Loss
Category 1 water loss
Category 1 water originates from a sanitary source and does not pose substantial risk from dermal, ingestion, or inhalation exposures. However, once clean water leaves the exit point, it might not remain clean once it contacts other surfaces or materials.
The standard does NOT say that the water must be drinkable to be a category 1 loss. It must come from a sanitary source and not have gathered any significant contamination after leaving the pipe or hose. Some factors that influence the water's cleanliness are the current use of the structure (such as a privte home), the general condition of the structure, previous water losses, and the age and history of the structure
