The unique patented PowerPurge® acts as an energy recovery system, collecting waste heat from the hottest section of the desiccant wheel and using it to help with the regeneration. This reduces the energy required for reactivation, while also reducing the discharge temperature of the process air, resulting in lower energy costs for post-cooling.
The Polygon HCU product line oﬀers an energy efficient advancement in dehumidification. The design combines cooling and desiccant dehumidification technologies in one package, utilizing the waste heat from the cooling cycle to reactivate the desiccant wheel. In hot, humid climates the HCU outperforms all other technologies with less energy and comfortable outlet temperatures.
