Suppression: Detect and Suppress Explosions in Milliseconds
 |
The
suppressant
works in two
ways: 1.
Chemically,
by interfering
with the
explosion's
reaction, & In a matter of milliseconds, a Fenwal Explosion Suppression System is designed to detect the buildup of pressure in an explosion and discharge an explosion suppressant into the enclosed space before destructive pressures are created. The explosion suppressant also creates a barrier between the combustible particles to prevent the further transfer of heat.

Isolation: Contain Explosions: Chemically or Mechanically
|
Fenwal
Isolation
Systems are
designed to
detect incipient
explosions and
react instantly
to keep the
deflagration
from spreading
to unprotected
areas or
interconnected
equipment.
The Chemical Type Isolation method discharges an explosion suppressant into the duck work to suppress the fireball and prevent it from reaching other plant areas or equipment. The Mechanical Type Isolation method produces the same results by triggering the release of a high speed knife valve that forms a mechanical barrier in the pipeline. Both types of systems are used to help prevent explosions from propagating to unprotected areas. Often combined for detonation containment, these systems are particularly suited to curtailing flame spread in support of explosion vents.
