Perfect Tire Pressure For Every Terrain

Central tire pressure control systems must be designed to meet the specific needs of each application – and the systems from Freudenberg Sealing Technologies deliver exactly that. At the same time, they adjust the tire pressure according to road and ground conditions as well as vehicle load. These systems save fuel, reduce excessive vehicle wear and decrease vibrations, offering the drivers a more comfortable ride.

Freudenberg’s CTIS technology features an innovative, double-lipped sealing component mounted inside the wheel hub. This design separates the oil in the wheel hub from the compressed air entering the tire, absorbing the compressed air flowing to and from the tire. This eliminates the need for a hose mounted on the outside of the tire. An air lip ensures stable CTIS operation at pressures up to 8 bar and circumferential speeds up to 4.5 m/s. The seal is pressure- and speed-optimized, which reduces the vehicle’s power loss. Freudenberg’s system offers the lowest power loss compared to conventional tire inflation systems, as the air pressure is equalized on both sides of the sealing lip. The resulting force minimizes the radial load on the sealing lip.

Freudenberg Sealing Technologies has already supplied CTIS sealing systems in series production for over 15 years, securing additional contracts with renowned manufacturers of agricultural and construction machinery and their suppliers. The CTIS system is manufactured in the company’s various production plants worldwide.

“The North American heavy-duty vehicle market in particular has been seeking solutions to system aging caused by high speeds and temperatures in heavy-duty applications,” Wolfram noted. “We are the right partner with the right technology to offer our customers the solutions they need. Freudenberg’s CTIS solutions save fuel, reduce carbon dioxide emissions and extend service life – all at the push of a button. It’s a real benefit to our customers.”
