ti.systems | CTIS
Our CTIS is an extremely robust and convenient tire inflation system for pressure adjustment on the go.
Thanks to our new ti.systems Wheel Valve (TISWV), trucks with prepared axles can be equipped with our purely pneumatic CTIS preset 4|1 or preset 4|2.
Once turned on, the system allows the user to select from up to 8 individually preset tire pressures with just a flick of the wrist and can be conveniently operated from the driver’s cabin. Only then, our TISWVs are opened and the air lines are under pressure. As soon as the desired pressure is reached and the system is turned off, all lines are pressureless and the TISWVs are closed – a very big advantage as the seals and rotary unions will wear significantly less and air cannot leak through the valves when the vehicle is standing still for longer periods of time.
The compact TISWV is adaptable to most rims and optionally comes with an integrated standard Vg8 valve.
It has fording ability and operates from -10°c up to +80°C.
The CTIS offers distinct advantages:
Doubling traction by adjusting tire pressure
Comfortable and precise tire pressure adjustment on the go
Fast and easy to operate
Optional: Different pressures for front | rear
No electric or electronic components
No danger of leaking air over night
Adaptable to most rims
Air supply by vehicles air brake system or a powerful ti.systems AIR SUPPLY
Preset pressures can be modified in a few minutes by authorized personel
The CTIS can be fitted on:
Trucks with prepared axles | 4×4 | 6×6 | 8×8 | single or twin tires
