Central Tire Inflation System
Features:
Wheel Valves
Normally closed design
isolates tires from potential
air system leaks, eliminating
tire leak down when parked.
Available options allow for
integration into aluminum
wheels eliminating the need
for external hoses.
)
Quick Release Valves
Serves as a remote air exhaust
port. Can be fitted with an external
hose to allow venting above deep
water fording levels.
Electronic Control Unit
Option
Provides operator selections
for terrain and can be
configured to optimize tire
pressures based on axle
loads. Has ability to control
engine speed, transmission shifting, ABS and axle differential
locks. J1587 and J1939 data link compatible. Built-in self
diagnostics. Field programmable.
Pressure Switch
Monitors vehicle wet tank
pressure. Provides air system priority to brakes which
suspends CTIS operation in
the event of low truck air
system pressure.
