Mojave Energy Systems has launched AquaDry, a hydronic liquid desiccant air handling system for commercial facilities with existing chilled water plants. The system is designed to deliver supply dewpoints down to 25°F (approx. -4°C) using conventional chilled water temperatures.
AquaDry uses building chilled water and low-temperature hot water to provide dewpoint control, reduce chiller capacity requirements, and lower energy consumption. According to Mojave Energy Systems, raising chilled water temperature by 6°F (approx. 3.3°C) can recover 12% in chiller capacity and 18% in efficiency.
The system is intended for facilities such as data centers, healthcare facilities, pharmaceutical manufacturing plants, laboratories, and industrial manufacturing floors. It uses low-grade hot water at 110–180°F (approx. 43–82°C) for desiccant regeneration and is compatible with waste heat recovery, boiler hot water, or solar thermal systems.
AquaDry requires chilled water at 28–55°F (approx. -2–13°C) and hot water at 110–180°F (approx. 43–82°C) connections from the building’s hydronic systems. Mojave Energy Systems said the system does not require glycol for sub-42°F (approx. 6°C) dewpoints, a separate reconditioning module, or complex field assembly.
“AquaDry runs on the chilled and hot water already in the building — an alternative to the depressed chilled water temperatures, glycol loops, and oversized coils conventional dehumidification requires,” said Aaron Meles, VP of Product, Mojave Energy Systems. “Because liquid desiccant removes moisture directly from the air without relying on chilled water to do the work, AquaDry can dehumidify more with less chiller tonnage. For buildings already at capacity, that avoids an expensive and disruptive chiller upgrade.”
