These are recent photos of the start-up phase of a Bry-Air desiccant dehumidifier that was integrated into a new custom air handling system serving a multi-million dollar electron microscope suite. Slides viewed at the atomic level with electron microscopes are typically prepared with liquid nitrogen. Maintaining humidity levels less than 10%RH is important to prevent condensation on the slides during viewing. There are several interesting things to note in these photos about the ability of a Bry-Air desiccant dehumidifier system to meet specific project requirements: 1) The building selected to house the electron microscope suite had limited space in the mechanical room. After discussing with exp Engineering it was decided to integrate a desiccant cassette section into an Energy Labs air handling unit. This reduced the overall equipment footprint plus matched up better to other existing AHUs on site. 2) Another complication of this fast track project was the limited overhead space inside the mechanical room. When a standard desiccant cassette is integrated into an AHU, the reactivation airstream is located on top of the AHU. Bry-Air engineering was able to configure the cassette so that the reactivation airstream was located on the side of the AHU.
The Bry-Air desiccant cassette was provided by Q Applied Systems who worked with exp Engineering and CMS Corp. during the design phase. University Mechanical was the project’s mechanical contractor. Bry-Air is a U.S. manufacturer of commercial and industrial desiccant dehumidifiers and environmental systems ranging from 100 CFM to 100,000 CFM with 2014 marking their 50th anniversary.
