Centralized Lab Exhaust System Utilizing A “ Cluster ” Stack Design
The “ cluster ” stack design was informed by industry research and environmental boundary layer wind tunnel validation . Our design enhances the dispersion of the lab exhaust plume emitted from the stack by allowing the exhaust streams from various exhaust stacks to merge as they leave the stack , thus maximizing the momentum of the airstream and the elevation at which the plume rises into the atmosphere . The benefits are better air quality at the project site , optimum fan energy efficiency , and simpler building operation through a more elegant lab exhaust system design utilizing less controlled components than a traditional lab exhaust system with bypass air .
