This FACO GEA Glatt AHU Dry Cooler Cooling Dehumidification Coil is in unused condition and is guaranteed to be fully functional. This item came from a large pharmaceutical company that had surplus inventory. We urge customers to view all photos as they show overall condition, included accessories, and functionality. Please Note: This unit was part of large crate that also included a Preheat Steam Coil as well as a Heating Coil Face Damper/Louver. These units were intended to be components for a larger Air Handling Unit that was never installed. This larger unit was most likely custom designed and as a result very little information could be located online. We will be happy to supply additional information as well as photos so please feel free to contact us with any questions.
