Author: Schirmer Engineering Corporation
Date of issue: February 2009


High volume low speed (HVLS) fans are in increasing use in storage and manufacturing facilities. However, the interaction of these fans and automatic sprinkler operation is unknown. In order to inform spacing and other installation requirements in NFPA 13, Standard for the Installation of Automatic Sprinklers, the Foundation initiated a research program. Phase I of this program which includes a literature review and small and large scale testing with a focus on ESFR sprinklers and rack storage is described in this report.
