Low-grain refrigerant dehumidifiers use refrigerant to temporarily lower the temperature of air passing through the unit, allowing moisture to be removed through condensation on its coils. Mobile Air & Power Rentals’ specialty division, Mobile DRi, provides a range of rental LGR dehumidifiers that work in some of the toughest moisture conditions to get the job done. Conventional dehumidifiers may be enough for personal use, but difficult projects such as water damage restoration require serious drying equipment for truly effective results.
