This lecture provides an overview of the various benefits of driving with an adjusted tire pressure in the field and on the road. The principle components of PTG‘s central tire inflation systems, CTIS, are a dual-line system with seals at nearly zero pressure in the air transmission unit, a main control unit based on a proportional valve system, and various operating panels. Examples of air transmission units for different axle geometries are given as well: the flange-axle solution, the non-driven trailer-axle solution, the bar-axle solution, and the portal-axle solution. Furthermore, the concept of a new sealing method for air transmission units is introduced. A list of PTG‘s hydraulic-driven compressors for a sufficient CTIS air supply is given, along with a description of the procedure for calculating the air requirement of each situation. In addition, PTG‘s main markets and sales channels are listed. The lecture ends with the outlook for new developments and future market requirements.
