INFO CENTER SPECIAL ADVERTISING SECTION RELIABLE CONTROLS POTTORFF'S ONLINE INFORMATION AND SELECTION TOOL (LIST™) Our louver selection tool is a state-of-the-art program that lets you choose louvers based on application and performance criteria. Designed for engineers and architects, it takes the guesswork out of choosing the right model for every job. We recently upgraded LIST and changed the manner in which the program handles volume airflow rates (cfm or m3/s). LIST will now evaluate free area velocity, pressure loss, and other characteristics based on the exact airflow rate specified by the user. http://www.pottorff.com/LIST/login.php www.info.hotims.com/54425-42 www.info.hotims.com/54425-44 www.info.hotims.com/54425-43 www.info.hotims.com/54425-50 www.info.hotims.com/54425-45 FEBRUARY 2015 ashrae.org ASHRAE JOURNAL 71
