The advantages of an adjusted Tyre Pressure• Reduced fuel consumption of the towing tractor in the field and on the road (10 % – 15 %)

• Example: 5 cm depth of track = + 10 % diesel consumption

• Reduced rolling resistance in the field and on the road

• Higher ride stability on the road at higher speeds

• Reduction of track depth caused through bigger footprint of the tyre

• Strong increase of towing force due to better interlocking of the tyre profile with the ground

• None/reduced soil compaction

• Higher yields

• Self cleaning effect of the profile through flexing tyres

• No tyre damages/less tyre wear

This does not effect tractors only, but also trailers and trailed im-plements. The necessary towing force of the trailer is reduced by reducing the track depth (Bulldozing-Effect).

Furthermore CTIS is a competitive advantage for a contractor. Farm-ers as their customers often demand low tyre pressures on their fields. Also the usage time in the season can be extended, because an op-eration under difficult soil conditions could be still possible with re-duced tyre pressure.

The advantages of the dual-line technology• High operational reliability due to automatically switching wheel valves with check functionality

• No pressure loss in the event of line breakage

• No annoying closing of ball valves (single-line technology) to avoid total loss of tyre pressure J

RDS/GW dual-line Tyre Inflation System for slurry tankers & trailers with

digital- or ISOBUS-controlmove. The ducts to the wheels lead through the drilled axles. The sys-tem is suitable for all slurry tankers and other trailers with appropri-ately prepared axles. The RDS 2L cannot be retrofitted without drill-ing the axles.

For this case we offer our System „AIRBOX/drive dual-line“! The compact dual line rotary unions featuring long-life grease filling (no greasing needed), high-quality seals and bearings are screwed into the axle hub.

PTG 2L Speed wheel valve • Automatically switching wheel valves with check functionality according to the patented and proven dual-line principle (unpressurised lines!)

• Flow-optimised design enables deflation times to be cut in half

• Integrated filter-sieve protects against dirt entering from the tyre

• Maintenance free

More PTG rotary unions• for drilled trailer axles such as ADR, FAD, Colaert Essieux

• Line system at zero pressure when switched off

• Automatically switching wheel valves with check functionality (i.e. no manually activated ball valves in the rims)

• No loss of tyre pressure if the line comes off

• Long life of rotary unions (only under pressure during adjustment)

• Optionally with various PTG air supply systems

The RDS dual-line technology Tyre Inflation System is a professional system for reliable and convenient tyre pressure adjustment on the

The automatically switching wheel valves with check functionality fit-ted in the rim promptly closes if the lines are cut off, to prevent pres-sure loss in the tyres.

The system is connected to the pneumatic brake system with a safety valve, so 6.5 bar pressure for the brake system is always guaranteed.

Trailers with large-volume tyres usually require separate air supply sys-tems. PTG offers a variety of air supply systems that switch on and off automatically as and when required.

Dual-line rotary union exclusively for BPW-axles!• Officially approved by BPW!

• Patented solution exclusively for BPW axles

• Optimized corrosion protection of inner axle components incl. bearings

• Maintenance free – no grease nipple

• Maximum airflow

• Easy and quick installation with standard tools

The system is operated from the cabin, optionally using the standard digital control panel or the ISOBUS-control

RDS/GW single-line Tyre Inflation System for slurry tankers & trailers with pneumatic-control

The RDS single-line technology Tyre Inflation System is a profession-al system for reliable and convenient tyre pressure adjustment on the move. The ducts to the wheels lead through the drilled axles. The system is suitable for all slurry tankers and other trailers with facto-ry predrilled axles. The RDS 1L cannot be retrofitted without drilling the axles.For this case we offer our System „AIRBOX/drive single-line“!

The compact single line rotary union featuring long-life grease fill-ing (no greasing needed), high-quality seals and bearings is screwed into the axle hub. Trailers with large-volume tyres usually require separate air supply sys-tems. PTG offers a variety of air supply systems that switch on and off automatically as and when required.

The system is connected to the pneumatic brake system using a safety valve, so 6.5 bar pressure for the brake system is always guaranteed. We can provide detailed air requirement calculations to help you se-lect the right airsupply system.

Control Systems for single-line Tyre Inflation Systems Control Systems for dual-line Tyre Inflation Systems

Pneumatic control for single-line Systems

Pneumatic control: The driver sets the required air pressure for both road and field once on the control panel with gauges outside the vehicle, which are then stored.

Using the control panel in the cabin, the driver simply selects the required mode (road or field); the control unit adjusts the pressure in all tyres to the preset values and switches off automatically. The system can also be switched off manually at any time.

Since the system is permanently connected to the tyres, the actual pressure gauge always indicates the current tyre pressure.

Digital control (RDS/control) for dual-line Systems

The electronic box is a universal control unit that enables the user to operate the tyre infla-tion systems of tractor and trailer at the same time. It also gives the option to access preset air pressure data by the press of a button.

Once activated, the system adjusts the tyre pressure in the selected tyres before switching off automatically.

The system can also be deactivated at any time by the press of a button.

• Controls Tyre Inflation Systems of tractor and trailer at the same time

• Preset of road- and field-pressures separately for front- and rear axle of the tractor as well as for the trailer.

ISOBUS-control for dual-line Systems

The operation of the tyre inflation systems uses the ISOBUS-terminal of the vehicle or the tractor, as the PTG-System is connected internally with the ISOBUS System.

Preset tyre pressures are set after opening the PTG page on the ISOBUS-terminal or via a connected Joystick.

• Controls Tyre Inflation Systems of tractor and trailer at the same time

• Preset of road- and field-pressures separately for front- and rear axle of the tractor as well as for the trailer.

• ISOBUS Joystick ready (AUX_N)

Air Supply System S2000 (2,000 l/min) and S4000 (4,000 l/min)The hydraulically driven screw compressors S2000 and S4000 are designed for use with two and three axle trailers. With a reliable piston motor and active cooling of the compressor lubricant, the unit is highly robust and efficient.

Air Supply System V2000 (2,000 l/min) and V4000 (4,000 l/min)The hydraulically driven vane compressors are the best choice for the agricultural use because of their robust compression principle.The main advantages of this compressor type are more compact design, extremly silent operation and a design for continously operation.
