Understanding the difference between Low Grain Refrigerant (LGR) dehumidifiers and regular refrigerant dehumidifiers can help you pick the right one for your needs — especially in restoration or high-moisture situations.
Both kind of dehumidifiers use a refrigeration cycle to remove moisture.
The main difference is that LGR dehumidifiers are more efficient at removing moisture in cooler, drier conditions. LGR dehumidifier works on a system of double cooling, lowering the temperature of moisture. The LGR dehumidifier with super-cooling technology made by PREAIR continues to dry the air into a lower humidity, pulls more water out of the walls, floors, ceilings, etc, and removes more water per kilowatt of electricity consumed than a similarly sized regular refrigerant dehumidifier.
Feature: | LGR Dehumidifier: |
Moisture Removal | Removes more water, especially as humidity drops. |
Performance | Works better in low humidity and cooler temps. |
Technology | Uses a super-cooling copper coil system to drop air temperature further before moisture extraction. |
Ideal Use | Water damage restoration, crawl spaces, basements, disaster cleanup. |
Cost | Typically more expensive, but more powerful. |
Feature: | Standard Dehumidifier: |
Moisture Removal | Effective in higher humidity (above 60%). |
Performance | Less efficient when temps/humidity drop. |
Technology | Single-stage cooling; basic coil system. |
Ideal Use | Home use, living areas, mild humidity control. |
Cost | More affordable, good for everyday needs. |
Situation: | Best Choice: |
Water damage, floods, crawl spaces | LGR |
Everyday home humidity control | Standard |
Cold basement or garage | LGR (works better in cooler air) |
Tight budget | Standard (but may be less efficient) |
Generally speaking, LGR dehumidifiers are heavy-duty, efficient, and good at handling cold and dry conditions. Standard dehumidifiers are solid for typical home use when humidity is high. Choose dehumidifier according to your specific needs. Contact us for suggestions or order bulk dehumidifiers.
