SmartFOAM
SYSTEM OVERVIEW
The Hale SmartFOAM Foam Proportioning Systems are
completely engineered, factory matched foam
proportioning systems that provides reliable, consistent
foam concentrate injection for Class “A” AND Class “B”
foam operations. The 1.7AHP and 2.1A systems are for
Class “A” only while the 3.3, 5.0, and 6.5 systems can
use Class “A” and Class “B”.
Hale SmartFOAM Foam systems accurately deliver from
0.1% to 10.0% (up to the capacity of the foam pump)
foam concentrate through a check valve/ injector fitting,
directly into the water discharge stream. It is then fed as
foam solution into a standard fog nozzle, an air aspirated
nozzle, or CAFS equipment, through the apparatus
discharge piping. A properly configured and installed
foam system with Hale recommended components
virtually eliminates contamination of the booster tank, fire
pump and relief valve with foam concentrate.
ROTARY PLUNGER PUMP (1.7 AHP, 2.1A)
The heart of the Hale SmartFOAM 2.1A and 1.7AHP
systems are an electric motor driven rotary plunger
pump. The pump is constructed of anodized aluminum
and stainless steel and is compatible with most Class
“A” foam concentrates. The pump is close coupled to the
electric motor thereby eliminating maintenance of an oil
filled gearbox.
A relief valve mounted on the foam pump and
constructed of brass, protects the foam pump and foam
concentrate discharge hoses from over pressurization
and damage.
ROTARY GEAR PUMP (3.3, 5.0, 6.5)
The heart of the Hale SmartFOAM 3.3, 5.0, and 6.5
systems is an electric motor driven rotary gear pump.
The pump is constructed of bronze and stainless steel
and is compatible with almost all foam concentrates. The
pump is close coupled to the electric motor thereby
eliminating maintenance of an oil-filled gearbox. A relief
valve mounted on the foam pump and constructed of
stainless steel, protects the foam pump and foam
concentrate discharge hoses from over pressurization
and damage.
SMARTFOAM CONTROL UNIT
The control unit, mounted on the operator panel, is the
single control point for the SmartFOAM system. Press
one of the preset buttons to enable foam concentrate
injection once water flow has been established. The 4.5”
direct sunlight viewable color display shows:
❑
Water flow rate
❑
Foam concentrate injection percentage
❑
Total water flowed
❑
Total foam concentrate used
❑
Foam pump capacity
The SmartFOAM control unit also provides plain-text
information and warnings as well as tutorials for
calibration. The user interface can be configured for the
modern SmartFOAM look or the classic FoamLogix look.
WATER FLOW SENSOR
Foam concentrate injection rate is controlled by a
computer chip in the control unit for accurate,
repeatable, reliable foam concentrate injection. A water
flow sensor constantly monitors water flow through the
discharge piping. The information from the flow sensor is
provided to the control unit by a shielded cable. When
the SmartFOAM system is activated at the control unit a
signal is sent through the control cable to the motor
controller to begin foam concentrate injection. The motor
controller then provides power to the electric motor. The
electric motor rotates the foam pump and foam
concentrate flows through the foam pump discharge to
the one piece check valve/injector fitting into the water
discharge stream.
Note: All Hale SmartFOAM Foam systems require a flow
sensor for operation.
FEEDBACK SENSOR
A feedback sensor in the foam pump discharge
measures foam concentrate flow. The water flow rate
and foam concentrate flow rate are constantly compared
by the computer chip in the control unit.
The motor speed is constantly adjusted to maintain the
operator selected foam concentrate injection rate. Since
the system is flow based, injection rate remains constant
regardless of changes in system pressure or the number
of discharges that are open (within the limits of the
system).
The maximum rated foam concentrate flow, in gallons
per minute, is denoted by the model number. Table 1

capacity at various foam concentrate injection rates for
