Air Handling Units incorporate energy recovery system.

Press Release Summary:

Integrated Custom Air Handling (ICA) units in active desiccant dehumidification systems are offered with optional PowerPurge(TM) energy recovery system. PowerPurge collects waste heat off hottest section of desiccant wheel and uses it to help with regeneration, reducing energy required for reactivation while lowering discharge temperature of process air.

Munters New PowerPurge(TM) Reduces Energy Requirements, Improves Performance for Desiccant Dehumidification Systems

Munters Dehumidification Division - Industrial introduces Power Purge(TM), an energy recovery option for Munters Integrated Custom Air Handling (ICA) units. When equipped in ICAs, the PowerPurge improves performance by delivering air at drier levels, while using significantly less energy than traditional active desiccant dehumidification systems.

"PowerPurge reduces both reactivation and postcooling energy," says Paul Dinnage, vice president of research and development for Munters. "The unique patent pending system acts as an energy recovery system, collecting waste heat off of the hottest section of the desiccant wheel and using it to help with the regeneration. This reduces the energy required for reactivation while lowering the discharge temperature of the process air, decreasing energy costs for post cooling."

"With energy costs skyrocketing, we recommend ICA users take advantage of this innovative new option," says Dinnage. "We have documented energy savings of $100,000 annually on a 28,000 cfm system with use of PowerPurge."

ICA units feature a desiccant wheel that rotates slowly between two primary airstreams, process and reactivation. In the process airstream, water vapor is removed as it passes through the desiccant wheel. This dehumidified air is then delivered to a
manufacturing process or space. The wheel then rotates into the reactivation sector where a heated airstream is passed through the wheel. The desiccant wheel releases the water vapor to this airstream. The majority of the energy required for the desiccant process is used in heating the reactivation airstream.

PowerPurge also can save on the initial capital investment. Equipping a desiccant system with PowerPurge can reduce the size of the desiccant rotor without diminishing the dehumidification capacity while still decreasing energy costs. "Because PowerPurge increases efficiency, a system that required, for example, an 86-inch desiccant wheel may only need a 60-inch wheel if equipped with this energy saving option," adds Dinnage.

PowerPurge is available in Munters ICA products in the U.S. The ICA line of full-featured, factory-built custom air handling systems incorporate many advanced features including an innovative double wall construction that incorporates a superior no-through metal design in either 2.5 or 4-inch wall thickness. Unlike other custom air handlers, the ICA maintains its no-through metal design on all surfaces, even the system base.

Munters, the originator of desiccant wheel technology, specializes in designing desiccant dehumidification units and air handling systems.

Munters is the world's largest manufacturer of dehumidification systems, providing equipment that humidifies, dehumidifies and cools air, controls emissions and dries water-damaged environments.

Munters America has operations in more than 30 locations throughout the United States, as well as in Argentina, Brazil and Mexico. Its parent company, Munters AB, is headquartered in Sweden and has operations in Europe, Asia, Africa and Australia.
