All piping coming in direct contact with the foam agent is immune to the agent; so deterioration of
plumbing is avoided.
This system is designed to operate at no more than 5 psi (34 kPa) on the suction side of the water pump.
System Capacity. The system has the ability to deliver the following minimum foam solution flow rates:
500 GPM (1,893 l/min) @ 6%
1,000 GPM (3,785 l/min) @ 3%
3.
Generator. The TFFT is equipped with a complete electrical power system. The generator is a Harrison
Model 15.0 MPC-160 TFFT 15 kW Hydraulic unit. The wiring and generator installation conform to
present National Electrical Code Standards of the National Fire Protection Association (NFPA). The
installation is designed for continuous operation without overheating and placing undue stress on
components.
The output of the generator is controlled by an internal hydraulic system. An electrical instrument panel
allows for the operator to monitor and control all electrical operations and output. The generator utilizes
the main chassis transmission to power the generator. An engine/transmission PTO unit drives the
generator, through a hydraulic pump and motor.
An electric/hydraulic valve supplies hydraulic fluid to the clutch engagement unit provided on the chassis
PTO drive.
4.
Generator Instruments and Controls. To properly monitor the generator performance, a digital meter
panel is located in passenger side rear compartment. The meter indicates the following items:
Voltage
Amperage for both lines
Generator run hours
Over current indication
Over temperature indication
Service required indication
"Power On" indication
Two (2) fuse holders with 2 amp fuses (for indicator light protection)
All instruments are accurate within +/- 2 percent.
