The short answer
The Core Mechanism: The Desiccant Wheel
An LGR dehumidifier operates using a rotating wheel coated with a moisture-absorbing desiccant material. As damp air passes through one section of the wheel, the desiccant attracts and holds water vapor from the air. This process separates the moisture from the air stream, allowing drier air to pass back into the room.
A separate, heated air stream then passes through a different section of the same wheel. This hot air reactivates the desiccant by driving the collected moisture out of it. The moisture-laden reactivation air is then vented outside, resetting the wheel for another cycle. This continuous rotation allows for consistent moisture removal.
Why Lgr Models Excel in Cooler Climates
Unlike refrigerant dehumidifiers that need warm air to function efficiently, LGR units are not dependent on air temperature. This makes them ideal for drying out spaces that are naturally cool or have been chilled by water intrusion. In an oceanic climate with mild wet winters and dry summers, these conditions are common. This capability is crucial for thorough drying after a leak or flood.
When the air is cold, refrigerant coils can frost over, stopping the drying process. An LGR dehumidifier avoids this problem entirely. Its desiccant-based system actively pulls water vapor from the air through chemical attraction, not condensation. This ensures drying continues steadily, which is vital for protecting wood, drywall, and insulation from prolonged dampness.
- They remove moisture effectively regardless of the air temperature.
- They do not rely on condensing moisture on cold coils, which can frost over.
- They maintain drying power in cold, damp basements and crawlspaces.
- They are often used during winter months or in coastal regions.
- They help prevent ice buildup that can halt other dehumidifier types.
- They are a key tool for structural drying after cold-weather pipe bursts.
The Role in Professional Water Damage Restoration
During a water damage event, local water damage pros use LGR dehumidifiers as part of a systematic drying strategy. They first extract standing water and then place these units strategically based on moisture mapping. The goal is to create balanced drying conditions, removing humidity from the air so that wet materials can release their moisture faster.
This equipment is essential for drying deep-seated moisture in walls, subfloors, and concrete. By controlling the humidity in a contained area, the pros help prevent secondary damage. Effective use of LGR dehumidifiers can significantly reduce the time needed for structural drying, helping to limit mold growth and material warping.
Comparing Lgr to Refrigerant Dehumidifiers
Refrigerant dehumidifiers cool air to condense moisture, similar to an air conditioner. They work very well in warm, humid conditions. However, their efficiency drops sharply when room temperatures fall below about 65 degrees Fahrenheit. In cooler environments, their coils frost, requiring a defrost cycle that interrupts drying.
LGR dehumidifiers, in contrast, perform consistently across a wide temperature range. They are often the preferred choice for initial drying phases in cool basements or after winter floods. For a complete restoration, the pros may use both types in different areas of a home to optimize the drying environment for speed and thoroughness.
Key Points for Homeowners on Lgr Use
If you are dealing with significant water damage, proper drying requires professional-grade equipment and knowledge. While you can rent consumer dehumidifiers, they lack the power and capacity for major incidents. An LGR dehumidifier used by the pros is a powerful industrial machine designed to run continuously and handle large volumes of air.
Correct placement and monitoring are key. The equipment needs adequate space for air intake and exhaust. Understanding this process can help you communicate with restoration professionals. They use moisture meters to track progress and adjust the equipment, ensuring hidden areas like wall cavities are completely dry before repairs begin.

Can I use an LGR dehumidifier myself after a small leak?
For a minor leak in a small, warm area, a home dehumidifier may suffice. For larger areas, cooler temperatures, or hidden moisture, the industrial capacity and setup of a professional LGR unit are necessary. Incorrect use can prolong dampness, leading to mold.
How long does an LGR dehumidifier need to run?
Drying time depends on the extent of water damage, the materials affected, and indoor conditions. The pros monitor moisture levels daily. Typically, structural drying takes several days, but complex jobs in cool, enclosed spaces can take a week or more.
Does insurance cover the use of this equipment?
Coverage depends on the cause of loss and your specific policy details. The use of industrial dehumidifiers like LGR models is a standard part of professional water mitigation. Policies vary, and your insurer decides what is covered.
