Foam chamber having a closable testing outlet

A foam chamber for a fire suppressant system that permits rapid and clean testing of foam chamber and vapor seal functionality comprising:

• (a) an inlet conduit for containing a fire suppressant fluid and further comprising a plurality of openings for the introduction of a second fluid for aeration of the fire suppressant fluid into a fire suppressant foam, an inlet end, and outlet end;
• (b) a second inlet conduit attached to the inlet conduit and adapted to fit within the inlet conduit and further comprising a plurality of openings for the introduction of the second fluid, an inlet end, and outlet end;
• (c) a dispersant device attached to and located within the inlet conduit and at the end of the second smaller inlet conduit for deflecting the fire suppressant fluid in a spray pattern;
• (d) an expansion enclosure comprising a removable closure for accessing an interior portion of the expansion enclosure, and an outlet attached to an outlet conduit for discharging the fire suppressant foam, and surrounding an expansion conduit attached to the inlet conduit and the expansion conduit further comprising an inlet end, a closable operation outlet terminating within the expansion enclosure having a vapor seal holder for removably holding a seal wherein the seal is either an unbreakable seal or a frangible seal, and a closable testing outlet terminating outside of the expansion enclosure having a vapor seal holder for removably holding a seal wherein the seal is either an unbreakable seal or a frangible seal.

A foam chamber for a fire suppressant system that permits rapid and clean testing of foam chamber and vapor seal functionality comprising:

• (a) an inlet conduit for receiving, expanding, and aerating a fire suppressant fluid into a fire suppressant foam;
• (b) an expansion enclosure for further expanding a fire suppressant foam terminating in an outlet conduit for discharging a fire suppressant foam into a storage tank;
• and
• (c) an expansion conduit for expanding a fire suppressant foam into which the inlet conduit terminates having an outlet terminating inside the expansion enclosure for allowing normal operation of the foam chamber and an outlet terminating outside the expansion enclosure for allowing testing of the foam chamber with each of the outlets having a vapor seal holder for holding either a frangible seal or an unbreakable seal,
• wherein the inlet conduit further comprises a second smaller inlet conduit for supporting a dispersant device located at its end for deflecting the fire suppressant fluid in a spray pattern, both the inlet conduit and the second smaller inlet conduit have a plurality of openings for receiving a second fluid for aerating the fire suppressant fluid into the fire suppressant foam, and
• wherein the expansion enclosure further comprises a removable closure for accessing the interior of the enclosure.
