Principles of RSD

1. Extraction (physical removal of water)

Removal of water in the liquid state is 500 times more efficient than changing liquid to vapour with air movers and removing the vapour with dehumidification. Specialty tools have been designed to remove maximum amount of water out of carpets and upholstery.

2. Air Flow (evaporation)

Once as much water as physically possible has been removed, the remaining water must be evaporated using high-velocity air. Over the last few years new types of air movers have been introduced that provide much higher air movement at lower amperage and are specifically designed for Rapid Structural Drying. Today's air movers sit on top of the floor and face the wall at a 45° angle. This increased airflow evaporates the water from the wet structural materials much more rapidly.

3. Dehumidification (balanced evaporation)

Dehumidifiers are used to balance evaporation. In other words, the moisture being put into the air from the air movers has to be taken out of the air, or secondary damage will occur. Without dehumidifiers, hygroscopic materials would absorb moisture out of the air and become damaged, drying would be delayed, and mould growth could occur. By utilizing the new low grain refrigerant dehumidifiers Rainbow International can remove much more moisture from the affected area than ever before.

4. Temperature (temperature control)

Maintaining proper temperature is critical in drying a structure quickly. Warm air holds more moisture than cool air; therefore, warm air will increase the rate of evaporation. Keeping the temperature of the affected area between 80° - 90° for the first 36 - 48 hours can assist drying enormously. Drying chambers can be utilized to contain the warmer temperatures to the affected area.
