CENTRAL TYRE INFLATION SYSTEMS
Why Choose TractAir CTIS?
Tyre pressures are critical if you want to get the best from your tractor, trailer or towed implement. Our central tyre pressure control system will save fuel, minimise ground compaction and reduce tyre wear by allowing you to maintain the correct tyre pressures for varying loads, field conditions and speeds. This is all possible on the move at the touch of a button due to a separate CTIS control unit or on the tractor display using ISObus.
In the field, low pressures are needed to spread the weight of the machine and to maximise grip. Conversely on the road higher pressures are needed to give stability, fuel efficiency and minimise tyre wear. Available for tractors, trailers, combines, sprayers, forage harvesters – in fact anything with wheels.
Just some of the benefits of our CTIS systems;
Reduce fuel consumption by up to 15%
Reduce tyre wear by up to 20%
Reduced soil compaction increases yield by up to 6%
Integrates into main tractor display using ISOBUS
Change tyre pressures while moving
Proven robust technology
Compatible with dual wheels
Inboard air connection available
Better self-cleaning of tyre tread while in the field
Change pressure while moving
Longer working season, especially in wet areas
Tested to last more than 10,000 hours
Pneumatically controlled check-valves. (Seals and air lines are only pressurised during pressure change).
No loss of pressure in case of damaged air lines or leaks
The PTG system is designed and made in Germany specifically for agricultural machines. The system uses only the best quality components and we offer full spares and support from our base in the UK.
PTG CTIS systems are easy to fit and will deliver a very quick return on investment.
Tractor CTIS, Forage Harvester CTIS and Sprayer CTIS
Trailer CTIS, Tanker CTIS and Towed Implement CTIS
A tractor tyre has to perform in a variety of conditions and cope with a wide range of loads and speeds. On the road, where 50k is becoming the norm, tyres need a higher pressure to reduce fuel consumption and wear. Higher road pressures also promote stability and improve road-holding. Conversely, in the field, low pressures are crucial to reduce compaction and wheel slip. Low field pressures also have a huge effect on fuel economy and comfort.
Tractors experience a huge difference in axle loads between different tasks and tyre pressure is vitally important to avoid tyre damage and to get the most from your machine. There is no compromise pressure that will work for all situations and manual changing is slow and tedious. Our system allows pressures to be changed from within the cab, while driving at any speed.
Our tractor CTIS, forage harvester CTIS and sprayer CTIS systems can be fitted to the front and rear of any machine. Our dual line systems are fail-safe and can be disconnected when travelling tight to hedges or through narrow gateways. On tractors equipped with sliding bar axles this can be via an internal air connection, keeping all pipework on the inside.
Trailer tyres have to carry a huge load both in the field and on the road. This weight changes dramatically when the trailer is filled or emptied, and if soil compaction and tyre damage are to be avoided the tyre pressures need to be correct for the load and speed.
It’s not practical to change tyre pressure manually when entering and leaving a field, so farmers are forced to compromise on a pressure that’s almost never correct.
TractAir CTIS offers the chance to change tyre pressures quickly and easily from the cab of the tractor, giving you the correct pressure at all times.
Our dual line trailer CTIS, tanker CTIS and towed implement CTIS systems are fail-safe and can be disconnected when travelling tight to hedges or through narrow gateways. On trailers equipped with hollow axles this can be via an internal air connection, keeping all pipework on the inside.
Our systems can be fitted to trailers, tankers, trailer sprayers, drills, in fact anything with wheels!
As standard the air supply comes from the tractors engine driven air brake compressor. We have a range of additional hydraulic driven compressors which are available to reduce inflation times.
Control of tyre pressure is done at the touch of a button using a dedicated control unit, or via ISObus on the tractor screen. Michelin have recently developed the Evobib tyre, which is designed with a revolutionary new tread pattern that takes advantage of CTIS to give outstanding performance on road and field.
If you also equip the tractor with CTIS, tractor and trailer pressure can be changed together, for true one touch tyre management.
