Using a revolutionary combination of desiccants and non-ozone depleting refrigerants, DryCool™ HD dehumidification system delivers cool, dry air for light commercial applications, improving comfort without increasing air conditioning loads. According to the manufacturer, the dehumidification system does not use heat to dry the air, which increases the need for air conditioning. Instead, the DryCool HD uses a desiccant dehumidification wheel and environmentally friendly refrigerant (R-410a) to remove heat and moisture from incoming air. This process uses 40 percent less energy than competing technologies, the company claims. The dehumidification system improves indoor comfort and helps prevent IAQ problems associated with moisture, such as mold, mildew, biological allergens, and odors.
