Efficient Equipment for Controlling Humidity in the Rainy Season

Choosing an LGR (Low Grain Refrigerant) dehumidifier during the rainy season is ideal if you need industrial-strength drying power, especially in high-humidity or flood-prone environments.

 

Why Choose an LGR Dehumidifier for the Rainy Season

1. Superior Drying Performance in Humid Conditions

LGR dehumidifiers remove more moisture than conventional units, especially when humidity is high (e.g., after heavy rain, floods, or in basements).

LGR dehumidifiers cool air below the dew point and use dual-stage condensation to extract extra moisture, even at lower temperatures.

2. Works in Cooler Spaces

Unlike standard compressor dehumidifiers, LGR units work efficiently in cooler temperatures (down to 33–35°F / 1°C).

A flood dehumidifier is perfect for storage rooms, garages, or unheated areas where moisture still builds up in the rainy season.

3. Faster Structural Drying

LGR dehumidifiers are widely used in water damage restoration because they can dry out walls, flooring, and furniture more thoroughly and faster.

Ideal after leaks, pipe bursts, or heavy storms that cause water seepage.

4. Better at Reaching Target Humidity

"Low Grain" means the unit can reduce absolute humidity to much lower levels—drier air, faster mold prevention.

Great for protecting wood, electronics, or anything sensitive to moisture.

5. Improve Comfort and Prevent Diseases

When the external environment is humid and hot, the function of the spleen and stomach is easily affected, leading to dysfunction in digestion, loss of appetite, bloating, diarrhea, etc. In the long run, it can cause chronic diseases such as chronic gastritis and gastric ulcers. Moreover, a humid and hot environment can exacerbate the dampness in the body, leading to skin diseases such as eczema and urticaria, as well as bone diseases such as arthritis and rheumatism.

LGR dehumidifiers can effectively control the indoor humidity level within a proper range. With their help, people will enjoy a dry and clean environment. Preair is a reliable dehumidifier supplier. Contact us if you need professional dehumidifiers.

6. Durability for Demanding Conditions

Built tough—usually with rugged plastic or steel housings, large wheels, and handles.

Withstands constant use and harsh conditions—ideal for rainy season environments where basic home units may fail or struggle.

 

Scenario of Using LGR Dehumidifiers

Scenario:	LGR Dehumidifier Benefit:
Basement dampness	Works well in cool, humid, enclosed spaces
Post-flood or water damage	Fast, thorough drying of structural materials
Mold prevention after heavy rain	Pulls moisture even from deep inside surfaces
Large open living areas	High moisture extraction rate + continuous use

 

Compared to Standard Dehumidifiers

Feature:	Standard Dehumidifier	LGR Dehumidifier
Moisture Removal Rate:	Moderate	Very High (85-165 PPD)
Performance at Low Temp:	Poor	Strong
Durability:	Light-duty	Rugged / Commercial-use
Price:	Lower (S$200–700)	Higher (S$800–3000)
Use Case:	Home/bedrooms	Restoration / large rooms

 

When LGR Dehumidifier Might Be Overkill

If you're just managing everyday humidity in bedrooms or small apartments, a dehumidifier for water leak is likely too expensive and noisy.

Whole home dehumidifiers (applied in crawl spaces and attics) are often more practical and energy-efficient for daily living.

 

When Choosing an LGR Dehumidifier

Drying after leaks or floods.

Have a large, damp, or poorly ventilated space.

Need maximum moisture extraction during prolonged rainy conditions.
