EQUIPMENT TO BE USED WITH PYROCAP B-136™
PYROCAP B-136™ turns water into a kind of “Super-water”. For that reason,
all equipment and application techniques used for delivering PYROCAP B-136™ are
similar to those used with water. The agent may be premixed in pumper engine holding
tanks, or proportioned with standard eduction equipment.
Nozzles
PYROCAP B-136™ is most effective with non-aspirated nozzles, such as the
Task Force nozzle, or equivalent, which is adjustable from straight stream to fog
settings.
Eductors
For PYROCAP B-136™ at 1, 3, or 6 percent concentration, eductors should be
set in the “water” position, and the pickup tube inserted in a 5-gallon container of the
product. Pressure at the pump should be sufficient to give 100 psi at the nozzle.
Generally, pressure of 200 psi at the pump will be sufficient, although a loss of pressure
to friction in the piping may require greater pressure. Nozzles and eductors must be
compatible to ensure effective use.
The flow of PYROCAP B-136™ should be metered at the eductor at 1, 3, or 6
percent, and the flow rate of delivery of agent-enhanced water will generally be 95 gpm
for Classes A, B, and D fires.
Concentration setting recommended:
Class A - 1 to 3%
Class B - 6%
Class D - 6%
