Explosion Isolation

Preventing Secondary Deflagrations

Explore how Fike’s fast-acting explosion isolation valves and suppression systems prevent flame propagation from reaching interconnected processes and ducts, protecting downstream equipment and, most importantly, its operators.

The Dangers of Secondary Explosions

History has shown that the most devastating dust explosions often occur after the initial deflagration propagates into downstream equipment, causing widespread damage and casualties. Learn how if not properly isolated, secondary explosions may propagate…
