Why Is It More Recommended to Use LGR Dehumidifier?

An LGR (Low Grain Refrigerant) dehumidifier is often recommended over conventional dehumidifiers, especially in demanding environments like flood restoration, basements, crawl spaces, or high-humidity climates.

Advantages of LGR Dehumidifiers

Much Lower Humidity Levels

Standard refrigerant dehumidifiers usually pull air down to ~40–50% RH.

LGR dehumidifiers can reduce air moisture far lower (down to ~10–20 grains per pound of air), which is critical for drying wet materials.

High Efficiency in Extreme Conditions

They work well even in very high humidity or cooler temperatures, where standard units often struggle or freeze up.

This makes them reliable for basements, crawl spaces, and post-flood situations.

Faster Drying Power

LGR dehumidifiers use advanced dual-cooling technology to pre-cool the air before it passes over the evaporator coil.

This increases water extraction rates, speeding up structural drying after leaks or floods.

Energy Savings

Because they remove more moisture per kilowatt of electricity, they are more cost-effective in the long run compared to running multiple smaller units.

Prevents Secondary Damage

By pulling humidity down further, LGR units help stop hidden mold growth, warping of wood, or corrosion in walls, subfloors, and furniture.

Built for Heavy-Duty Use

Flood restoration dehumidifiers are rugged, portable, and designed for contractors, restoration professionals, and long-term residential/commercial protection.
