Designed to fit all types of cooking appliances, hoods and ductwork, the WHDR System features a wet chemical agent that provides Siteer flame knockdown and faster suppression of grease and oil fires, while blanketing the protected area with a foamy layer to cool and prevent fire reflash. On duty around the clock, yet out of sight, the Kidde WHDR System exceeds the requirements of U.L. 300 and offers wider coverage with less hardware than any other system.
Kidde Wet Chemical Systems exceed the UL-300 standard. This new standard is brought about by the evolution of new cooking trends and appliances that operate at higher temperatures. Kidde Systems also comply with NFPA 96 and 17A standards.
