Fike”s Fire Limiting Explosion Vent panel, Flex-V, is an explosion-protection device, uniquely designed to allow fire-fighting agents the opportunity to effectively control fire situations. Unlike traditional explosion venting, the Flex-V is designed to return to its original position at the end of the venting process, thereby re-covering approximately 90 percent of the vent-relief area, shortening the venting process and reducing the ingress of fresh air (oxygen). The Flex-V “re-closure” is designed to reduce the risk of secondary explosions within the process vessel and allow for more efficient post-explosion fire fighting, because the suppression agents can be injected into a re-confined space. The FLEX-V can also open inward, offering protection against vessel collapse due to post explosion vacuum.
