Desiccant Dehumidification

Desiccant dehumidifiers work under the principle of sorption. These types of dehumidifier’s place air in contact with hygroscopic material. There are different advantages of using desiccants in lieu of refrigerant dehumidifiers. They work well in temperatures below 32 degrees. They create low vapor pressure, 10-15 humidity ratio. They are more effective in a Class 4 drying situation. Desiccant dehumidifiers do not cool air rather is heats. Usually these dehumidifiers produce a higher grain depression than refrigerant dehumidifiers. Desiccant dehumidifiers range from 75-20,000+ cfm in our industry. A good way to think of how a desiccant works is similar to a clothes dryer. These machines can increase the existing temperature up to approximately 50 degrees F. SERVPRO of Newark owns a few of these big dehumidifiers.
