The purpose of this project was to improve the existing High Temperature Filter Test Unit (HTTU) by optimizing performance and adding new features. These features include viewing ports and a camera system for observation of tests, a leak detection system, and a flame impingement system. Additional considerations included improving the current operation of the HTTU by reducing test time and energy loss. The HTTU is designed to test High Efficiency Particulate Air (HEPA) filters at temperatures up to 1300 ˚F, creating conditions which simulate a fire in a chemical processing facility. The HTTU was originally built as a Cal Poly senior project in 2011-2012. A second senior project team has implemented a control system and a fully automated test procedure. This final report presents our solutions to the problems posed to us, including manufacturing, implementation, and test results. The report builds off of the project proposal, the conceptual design report, and the critical design report, which was presented to the staff of Lawrence Livermore National Laboratory (LLNL) on February 8th,2013. Design and specification development have been moved to Appendix C – Design Development in order to focus on the current design.
