Viking Sprinkler VK503 may be used in the protection of ordinary types of storage. However, it is primarily intended to protect the following types of storage, which tend to produce severe-challenge fires: double, multiple row, and portable open rack storage (no open-top containers or solid shelves).

  • Encapsulated or unencapsulated Class I, II, III, and IV commodities
  • Cartoned and uncartoned unexpanded plastics
  • Cartoned and uncartoned expanded plastics
