Water Damage Restoration
When dealing with water damage restoration, using an LGR (Low Grain Refrigerant) dehumidifier and a centrifugal air mover can significantly expedite the drying process. Begin by assessing the extent of the water damage. Identify affected areas and determine the severity of moisture saturation.

1.Remove Standing Water:
If there's standing water, use a water pump to remove as much water as possible.

2.Place LGR Dehumidifier:
Set up the LGR dehumidifier in the affected area. LGR dehumidifiers are highly effective in removing moisture from the air, even in low humidity conditions. Place the unit centrally to maximize coverage.

3.Use a Centrifugal Air Mover:
Position the centrifugal air mover strategically to enhance the evaporation process. These air movers are designed to deliver high-velocity airflow, accelerating the drying of wet surfaces.

4.Create Air Circulation:
Arrange the air mover to create a circular airflow pattern, directing air across wet surfaces, including walls, floors, and affected contents. This helps in efficient moisture evaporation.

5.Move Air Mover as Needed:
Periodically reposition the air mover to target different areas, ensuring comprehensive drying coverage.


​​​​​​​
6.Monitor Humidity Levels:
Regularly monitor humidity levels using a hygrometer. Adjust the settings on the LGR dehumidifier to maintain optimal humidity levels for effective drying.
7.Use Multiple Units if Necessary:
Depending on the size of the affected area, consider using multiple LGR dehumidifiers and air movers to expedite the drying process.

8.Ventilation:
Ensure proper ventilation in the space. If conditions permit, open windows and doors to facilitate the exchange of moist indoor air with drier outdoor air.

9.Final Inspection:
Once the affected area shows signs of significant drying, conduct a final inspection. Ensure that all surfaces are dry to prevent mold and mildew growth.

10.Document the Restoration Process:
Keep detailed records of the restoration process, including before-and-after photos, humidity levels, and the duration of equipment operation. This documentation may be valuable for insurance claims and future reference.

  • How much does a whole home dehumidifier cost?

    Preair provides high quality whole home dehumidifiers at a ex-factory price. The specific price you can find at our online shop on Alibaba.
  • Do dehumidifiers work in low humidity?

    Dehumidifiers are effective in environments with high humidity and can be crucial for controlling mold growth and preventing other moisture-related issues. 
    If you want to use a dehumidifier in a low-humidity area, it is recommended to measure the RH level of the area repeatedly and choose a dehumidifier that can still work in a relatively low humidity condition. The WH, ZETA and CFZ series of dehumidifiers can work between the 10%-90% RH. Want to buy efficient and powerful dehumidifiers? Contact Preair first.
