The first thing we will do when you experience water damage is extract all of the standing water. We then determine how much equipment will be needed to dry the home or structure. When exposed to water, most objects will absorb some of the water or moisture making them damp or wet. Every material is capable of holding a certain amount of water before becoming saturated or get to the level where it can’t hold any more. On the molecular level, water molecules have filled the space between or attached themselves to the material. By drying the materials we are providing an escape for the water molecules from the material and into the surrounding air.
Dehumidifiers are run to reduce the vapor pressure and pull the water molecules from the air. This allows the air to accept more new water molecules from the materials being dried. The drier the air in the home or structure, the faster it will accept the water vapor for the wet and drying materials, thus requiring the area to have a low humidity. Air movers will be strategically placed creating an even airflow to the most critical areas of the structure.
The dehumidifiers placed on the job will vary in type and size depending on what is required. Each size and type will be able to “pull” a certain amount of water vapor out of the air. A typical flood job has a relative humidity in the range of 85% – 90%.
► Electric dehumidification works by passing air over refrigerated coils to condense water vapor.
► Desiccant dehumidifiers work when moist incoming air flows over a wheel filled with a silica gel desiccant.
A desiccant is a material that attracts and holds moisture. This material acts like a sponge drawing moisture from the air (sorption). When the wheel rotates through heated exhaust air, the moisture evaporates (desorption) and is carried outside.
This process absorbs moisture without ice build-up and is not limited by low temperatures. A desiccant dehumidifier supplies air with a relative humidity in the range of 4% to 8%.
Our certified technician experts will evaluate your water damaged area to determine the best and quickest way to dry your home or structure. In most cases, we'll establish a drying chamber to dry the affected area more efficiently.
The drying chamber will separate the wet areas from the dry areas and allow us to control and monitor the temperature and conditions more closely and dry the area more quickly. Drying chambers can be created in many ways and will vary by the needs of the job. In some cases, we may create more than one drying chamber in the same home or structure in insure the job is getting done quickly and efficiently.
The equipment used to dry your home or structure will also vary by the needs of the job. While your home or structures effected areas are drying, that moisture is pushed into the air. To remove moisture from the air in the area of your water damaged area, there are three different types of dehumidifiers used.
- Commercial Grade Refrigerant Dehumidifiers
- Low-Grain Refrigerant Dehumidifiers
- Desiccant Dehumidifiers
Commercial Grade Refrigerant DehumidifiersWork by passing air over refrigerated coils to condense water vapor. These dehumidifiers are calibrated and designed for high moisture environments.
Low-Grain Refrigerant Dehumidifiersprovide the best moisture removal and produce air that is dryer with less moisture then the commercial grade units. They are also more energy efficient and pull the grains down much lower. The water droplets drip into a collector and is discharged from the humidifier through pumps.
Desiccant Dehumidifiersuse a silica gel desiccant that attracts and holds moisture. Incoming moist air flows over a wheel filled with the desiccant. Then the wheel rotates through the heated exhaust air and evaporates the moisture and is carried outside through venting tubes.
