After cooling and initial moisture removal via the cooling coil, supply air flows through the CDQ desiccant wheel, which attracts and holds water vapor from the saturated air. Rather than lifting the entire air handler to put it in place, the modular unit was raised to the platform in eight sections where it was assembled. Installed 24 feet above the production floor is a Trane Performance Climate Changer™ air handler with a CDQ™ (Cool, Dry, Quiet) wheel to handle dehumidification and space cooling demands. To reduce energy use and meet sustainability requirements, a free cooler unit was also installed, allowing the scroll chiller to remain idle when low outdoor temperatures enable the free cooler to take on the full load. With the limited building footprint, the chiller was installed outside to open up and allow more useable inside space for the brewery equipment and operation. Based on a trusted relationship that spanned seventeen years, VHV contacted Trane to discuss project challenges and the best mix of HVAC equipment and controls to support the operation.Īn 80-ton high-efficiency air-cooled Trane® CGAM scroll chiller, selected for the facility, features onboard pumps with variable frequency drive, and is extremely quiet, helping to reduce energy use and create a comfortable environment for employees and visitors. The brewery’s construction manager brought the VHV Company in as their design/build contractor based on the company’s knowledge of the brewery process, and experience with brewery applications. “The kind of place where you want to be, from everyone’s point of view." Solution “We wanted to create a comfortable atmosphere,” said John Kimmich, co-owner and head brewer at The Alchemist. To live up to their environmental responsibility, owners sought to make the facility as efficient as possible, and also adhere to the town's odor control and waste handling requirements. Comfort was also key, with the brewery wishing to maintain a 74 degree indoor temperature and proper ventilation in the open floor plan. It was critical to control humidity for the space and to keep the process equipment and floors as dry as possible for safety purposes. With a number of wash down and boiling procedures inherent in the beer brewing process, humidity control was a top priority as The Alchemist planned construction of its new Stowe facility.
