Following an on-site system review, the first two Spirovents were installed in an equipment room serving two residence halls with recurring problems.  Positive results were immediate and since that time The University of Delaware has become one of our largest higher-ed customers.  Beyond the academic, research, and residence halls there is a 16" combination air dirt unit installed in the Laird Plant to replace an undersized centrifugal during the plant renovation and a custom fabricated 30" combination unit in the ECUP.
