1 System Overview
The Hale FoamLogix Models 3.3, 5.0 and 6.5 Foam Proportioning Systems are
completely engineered, factory matched foam proportioning systems that provide
reliable, consistent foam concentrate injection for Class “A” and Class “B” foam
operations.
Hale FoamLogix Foam Systems accurately deliver from 0.1% to 10.0% foam con-
centrate 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 virtu-
ally eliminates contamination of the booster tank, fire pump and relief valve with
foam concentrate.
2.1 ROTARY GEAR PUMP
The heart of the Hale FoamLogix 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 con-
structed of stainless steel, protects the foam pump and foam concentrate
discharge hoses from over pressurization and damage.
2.2 CONTROL UNIT
The control unit, mounted on the operator panel, is the single control point
for the FoamLogix system. Pressing the ON button starts foam concentrate
injection. A super bright digital LED display shows the:
❑ Water flow rate
❑ Total water flow
❑ Foam concentrate injection percentage
❑ Total foam concentrate used, depending on the display mode selected
A bar graph indicates the approximate system capacity being used. Adjust-
ment of the foam concentrate injection rate is accomplished by pressing the
appropriate button while the system is operating.
