How Do LGR Dehumidifiers Work for Water Damage?

LGR (Low Grain Refrigerant) dehumidifiers are specialized drying machines designed for water damage restoration. They remove large amounts of moisture from the air and help extract trapped water from building materials such as drywall, wood, carpets, and concrete. Compared with standard refrigerant dehumidifiers, LGR units can achieve much lower humidity levels, making them one of the most effective tools for flood and leak recovery.

1. Removing Moisture from Humid Air

After water damage, the indoor environment becomes saturated with moisture. Wet materials continuously release water vapor into the air, creating conditions where mold can grow.

An LGR dehumidifier works by pulling humid air into the machine using a powerful fan. The air then passes over a cold evaporator coil, where the temperature is lowered below the dew point. As the air cools, water vapor condenses into liquid water and is collected in a drain tank or removed through a drain hose or condensate pump.

2. Achieving Low Humidity Levels

The key advantage of an LGR dehumidifier is its ability to remove moisture beyond the capability of conventional units.

A typical refrigerant dehumidifier may reduce indoor humidity to around 40–50% RH under suitable conditions. An LGR unit uses an additional cooling stage and heat exchange process to further dry the air, often reaching very low humidity levels (approximately 10–20% RH in ideal restoration conditions).

This extremely dry air increases the vapor pressure difference (VPD) between wet materials and the surrounding air. As a result, moisture inside walls, floors, and furniture evaporates faster and can be removed more efficiently.

3. Recycling Heat to Improve Drying Efficiency

During operation, LGR dehumidifiers recover heat generated during the refrigeration process. After moisture is removed, the dry air is reheated slightly before being released back into the room.

The warmer, drier air:

Absorbs more moisture from wet materials.

Speeds up evaporation.

Helps maintain efficient drying performance.

This makes LGR equipment highly effective even in challenging water damage environments.

4. Working Together with Air Movers

LGR dehumidifiers are most effective when used with high-velocity air movers. Air movers circulate air across wet surfaces, encouraging moisture evaporation. The humid air is then captured by the LGR dehumidifier and dried.

The typical drying process is:

Wet materials → Air movers increase evaporation → Humid air enters LGR dehumidifier → Moisture is removed → Dry air returns to the room

This continuous cycle accelerates structural drying.

5. Why LGR Dehumidifiers Are Preferred for Water Damage Restoration

LGR dehumidifiers are widely used by professional restoration companies because they offer:

High moisture removal capacity for floods and leaks.

Faster drying times compared with standard dehumidifiers.

Low humidity output to prevent mold growth.

Portable designs with wheels for easy transportation.

Continuous drainage options for long-term operation.

Reliable performance in demanding restoration environments.

LGR dehumidifiers work for water damage by continuously extracting moisture from the air and creating an environment where wet building materials can dry faster. By combining advanced refrigeration technology with powerful airflow and low humidity control, LGR units help reduce drying time, prevent secondary damage, and minimize the risk of mold growth after floods, leaks, and other moisture-related disasters.

Best Automatic Dehumidifier for Sale

The LGR105 dehumidifier is a device designed to reduce and maintain the humidity level in a specific area automatically. High humidity can lead to various issues, such as mold growth, musty odours, and damage to furniture or electronics. It is necessary to use an automatic dehumidifier with WiFi to control humidity, which has an Automatic Shut-Off function. Once the desired humidity level is reached, the dehumidifier will automatically shut off to conserve energy and prevent over-drying.
