One of the laboratories needed a canopy hood and rooftop stack system to capture and exhaust odors and fumes created during the research experiments. Previously, the university's physical plant engineering department had built its own custom hood stacks on-site, but limited space, funding, and time prompted the project estimator at Texas Tech to look into other options. External funding was available to fund the project if the university could find a way of completing the project during the timeframe in which funding was available.
After reviewing the information on the Greenheck laboratory exhaust system, Gamel and Halley got together with Mike Powell of Anthony Mechanical, the mechanical contractor. Collectively, all agreed that Greenheck's lab exhaust system was the right choice for the project.
