Foam Supply Section
1. Foam Storage Tank
Foam concentrate is stored inside a stainless steel pressure
vessel type tank
(T1) stamped according to ASME Section
VIII Div. 1. Storage tank is normally unpressurized; maximum
working pressure is 150 psi (1033 kPa). The tank is supplied
with a safety relief valve
(T8) set at 135 psi (930 kPa) for
protection against over-pressurization.
Foam storage tank is factory assembled and includes all the
valves, trim and hardware as shown on Figure 2. Manual
valves are provided to fill the tank
(T9) with foam concentrate
and to release the air pressure (T6) after a CAF discharge. A
sight gauge (T5) is also provided to allow visual verification of
the tank foam concentrate normal level.
2. Foam Concentrate
CAF system shall be used with the following foam
concentrates and concentrations:
Foam concentrate Concentration
Hydrocarbons
National Foam Aer-O-Lite 3% 2%
National Foam Aer-O-Water 3EM 3% 2%
Polar Solvents
Ansul Ansulite 3X3 LV 6%
Shelf Life
The shelf life of any foam concentrate is maximized by proper
storage conditions and maintenance. Factors affecting shelf
life are wide temperature changes, extreme high or low
temperatures, evaporation, dilution, and contamination by
foreign materials. Properly stored foam concentrates have
been tested and shown no significant loss of fire fighting
performance, even after 15 years. For further details, see the
Foam Concentrate Data Sheet.
Environmental and Toxicological Information
Foam concentrates used with Compressed Air Foam Systems
are biodegradable. However, as with any substance, care
should be taken to prevent discharge from entering ground
surface water, or storm drains. Since facilities vary widely by
location, disposal should be made in accordance with federal,
state and local regulations.
For further details, see the foam
Concentrate Data Sheet and Material Safety Data Sheet.
3. Foam tank design and selection
The capacity established at the design stage is based on both
the maximum system flow and discharge time required for the
largest single hazard protected or group of hazards that are
protected simultaneously; FireFlex's design software will take
that into account when calculating the system's capacity.
Consequently, multiple foam tanks can be installed in parallel
to satisfy project requirements.
4. Interconnection Piping to ICAF System
There are two interconnection lines provided on all foam
storage tanks. One connection is used to pressurize the
foam storage tank with compressed air
(circled item 3) , the
other to provide foam concentrate to the mixing chamber
(circled item 2) . Piping between the foam storage tank and
the ICAF System is factory prepared according to the
installation arrangement and supplied with the system.
