1.
DRY CHEMICAL TANK. Holds 450 pounds (204 kilograms) of dry chemical agent at 220-240 psi (1518-1656
kPa) operating pressure.
2.
AFFF TANK. Holds 100 gallons (376 liters) of AFFF mix (water and AFFF concentrate) at 220-240 psi
(15181656 kPa) operating pressure. The tank is lined for corrosion protection and has an electric heater around
it to prevent freezing.
3.
CYLINDERS Assembly. Two are provided, each pressurizes one fire-fighting agent tank. Each cylinder contains
300 cubic feet 85 cubic meters) of nitrogen at 2400 psi (16560 kPa) when fully charged. Quick opening lever
operated valves are provided for ease of use.
4.
REGULATING VALVES. High volume pressure regulators that are preset to reduce nitrogen pressure to 220240
psi (1518-1656 kPa) working pressure.
5.
BALL VALVES. Control flow of fire-fighting agent (to pressurize tank) or nitrogen (for hose blowdown) through
discharge plumbing.
6.
BALL VALVES. Control flow of nitrogen to the fire-fighting agent tank.
7.
BALL VALVES. Control flow of nitrogen to the hose lines to clean and dry them.
8.
CHECK VALVES. Prevent back-flow of the fire-fighting agents into the respective nitrogen regulators.
9.
RELIEF VALVES. Self-resetting valve set at 250 psi (1725 kPa) used to guard against over pressurization of the
system.
10.
HEATER ASSEMBLY. Electric heater used to heat AFFF tank when tank temperature falls below 45° F (7° C).
Heater is equipped with a 120 vac male power plug and cord.
11.
HOSE REEL. Used to store 150 feet (46 meters) of fire hose assembly. Equipped with hand crank to manually
rewind the hose onto the reel.
12.
Hose ASSEMBLY. Two one-inch (2.5 centimeters), non-collapsible hoses 150 feet (46 meters) long and
encased in a woven polyester jacket. Used to carry the fire-fighting agents to the discharge nozzles.
13.
FIRE HOSE NOZZLE. Used to control the flow of fire-fighting agents onto a fire and to disperse the agent in a
predetermined pattern effectively for each agent.
14.
SKID FRAME. Steel frame assembly to mount and support the Fire Suppression Equipment Set components.
Provides a lifting bar for lifting the set as well as a lifting eye on each corner. Forklift channels are also provided
for lifting.
15.
TRAILER. Two wheeled trailer that the Fire Suppression Equipment Set skid is mounted on for ease of
movement. Equipped with individual hand parking brakes for each wheel. An adjustable lunette is provided for
towing, and tie downs are provided on each corner to secure the unit during transportation.
16.
CYLINDER VALVE. Quick-opening lever operated or hand wheel operated valve to allow for quick and easy
opening of cylinder.
17.
CRANK ASSEMBLY. Provides means to manually rewind the fire hose assembly back onto the hose reel.
18.
QUICK COUPLING HALF (Outlet). Used to quickly and easily disconnect the fire hose assembly and connect
the auxiliary mobile fire hose assembly.
19.
PARKING BRAKE ASSEMBLY (EACH WHEEL). When set, prevents the trailer from moving.
20.
REWIND BRAKE ASSEMBLY. An adjustable drag used to prevent the hose from unwinding from hose reel
under its own weight while allowing enough slip to easily pull the hose from reel when needed.
