The new PowerPurge is an energy-recovery option for Munters Integrated Custom Air Handling units. According to Munters, when equipped in ICAs, the PowerPurge improves performance by delivering air at drier levels, while using less energy than traditional active desiccant dehumidification systems. The 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. ICA units feature a desiccant wheel that rotates two primary airstreams, process and reactivation.
