WHY DO YOU WANT A TYRE INFLATION SYSTEM? Fuel consumption and tyre replacements cost a lot of money. You need all your farmland to cover these expenses with an optimal crop production and harvest. A Tyre Inflation System is the key to costs savings, increased safety and productivity improvement. With the new weather we have longer wet periods so be prepared. QTIS is the manufacturer of all components you need to achieve your goals: reliable, smart and affordable Tyre Inflation System. Years of experience in the agricultural market has provided us with insight of the issues that persist in commonly used Tyre Inflation Systems. This motivated us to improve each component that makes up these systems and redesign them in such a way that we tackle all known problems. Our design approach, to incorporate modern technologies and combining it with dedicated mechanical design, resulted in our Single Line System (SLS) technology. This SLS technology, with only one airline for every tyre, allows for straightforward control, faster installation, simpler standard components, more reliability and lower overall costs. In the navigation above you find an overview of all the different QTIS components, together forming the ideal Tyre Inflation System as we see it. • Less tyre wear, more effective field hours

PRESSURE / VALVE BLOCK Using a proportional pressure regulating valve we are able to set every tyre pressure quickly, accurately and continuously. This enables us to only use a single airline per tyre in our tyre inflation system. The maximum capacity of the pressure regulator is 3000Nl/min.

After the required pressure is set the valve block connects this to the tyre to allow for inflating or deflating the tyre. For large tractor-trailer combinations, an additional valve block can be mounted on the trailer body. Multiple valve blocks can be installed using the same pressure block.
• No overshoot and no undershoot when pressures are set, every tyre reaches the targeted pressure quickly and correctly in one go
• Pressure Block: 3000 Nl/min and 0-9 bar (0,9 MPa), IP65 rating, self-diagnosis feature, feedback and alarm function, 5 μm filtration, serves all control valves
• Valve Block: 3/2 NC control valves 1650 Nl/min and 0-8 bar (0,8 MPa), one valve per tyre, separated exhaust channels
• Allows for modular placement of additional valve blocks to achieve short distances between valve and tyre for optimal responses

PRESSURE BLOCK A pressure block with a proportionally controlled pressure regulator facilitates our new SLS technology, where different pressures in a single airline either inflate or deflate the tyre.

The valve block will connect the set pressure with each individual pressure or deflate the single airline complete when the required pressure is set. Multiple valve blocks can be installed using only one pressure block.
• No overshoot and no undershoot when pressures are set, every tyre reaches the targeted pressure quickly and correctly in one go

We have been selling and designing rotary joints for all industries the past 30 years and our proposal to the market is to use one of the three QTIS rotary joints. The old school solution with an outboard rotary joint which makes you vehicle wider than the allowed width, the radial rotary joint for those situations where a central bore in the axle is not an option, or the axial rotary joint inside the hub cap for a space, time and money saving solution for axles with a central bore. OUTBOARD ROTARY JOINT RADIAL ROTARY JOINT AXIAL ROTARY JOINT OUTBOARD ROTARY JOINT The outboard rotary joint has been the most common solution for our Tyre Inflation System since decades. Simple. Reliable. Cost efficient. Downside of the system design is the increased vehicle width which requires adaptation on the public road.

QTIS has provided its OEM customers with this solution, both single line and double line versions. In all applications we use mechanical seals. This everlasting design concept has proven itself as the best sealing method.

Optionally we supply our customers with all the necessary components as one part number as customer specific solutions.
• Different nominal sizes
• Custom design possible for OEM
• Mechanical seals for the best lifetime possible
• Non-corroding materials
• One and two channel versions
• Optionally including brackets, fittings as logistical service

WHEEL VALVE The wheel valve makes SLS technology possible through the pressure-controlled functions of the valve.

When the airline is pressureless the tyre is closed off and maintains its pressure. When the airline pressures are a few bars above the tyre pressure, the tyre will be inflated. When the airline pressure is above 8 bar the wheel valve will switch into another position however, and the tyre will be exhausted.
• Mounted via welded socket onto the rim
• Pressure controlled valve for inflating and deflating
• No tyre-air back through the system
• Filters prevent pollution from tyres into the wheel valve
• High flow capacity

TYRE PRESSURE SENSOR Only a pressure sensor in the tyre measures accurately, without dynamic flow losses you will have when you measure “tire” pressure in an airflow of a pipe. Tyre pressure should be measured in the tyre.

We developed a multifunctional Tyre Pressure Measuring System for you. Our TPMS sensors, mounted in your tyre, have bigger antenna and a 4x bigger battery than usual. Every 0,05 bar pressure change is reported, as well as tyre temperatures and the battery status.

To amplify the sensor signals between vehicles you can use a QTIS Repeater which will send the amplified sensor signals to our two receivers. We have a Screen Receiver which is intended for stand alone use, where you are interested in the status of the tyres, but not in inflating or deflating them. The Screen Receiver is mounted as a small screen in the tractor-cabin, and can work with many different trailers which will report tyre pressures automatically (drop and hook).

Alternatively we have a CAN Receiver which will convert all TPMS sensor signals in CAN J1939 code for import in the vehicles ECU control system, or in the QTIS Electronic Control Unit. In this case tyre pressure signals can easily be used for inflation and deflation control, in combination with de other QTIS products.
• Precise pressure measurements inside the tyre
• In-tyre temperature signals and leakage warnings
• Repeaters for signal amplification
• Receiver with CAN J1939 output
• Automatic matching of tyre locations to the VT
• No dynamic pressure measurements, so no misreading’s
• Large battery >7 years lifetime, low battery warning
• Receiver with Screen or CAN J1939 output

Back (small air flow) (standard air flow) (big air flow flow) REFRIGERANT DRYER Water-vapour, condensate and dewpoint explained The air we breathe contains water-vapour. We do not see it, or smell it, but the amount of water-vapour changes over the seasons and causes hot dry summer days, and foggy autumn mornings.

The warmer the air is, the more weight of water-vapour it can carry. Look for the maximum contents in the table. We use relative humidity when the maximum weight of water-vapour in the air is not reached.

So, we can see when air cools down, the maximum weight of the water-vapour in the air lowers. First the cooling air has increased relative humidity percentages, but at some point the water-vapour has saturated the air, and it starts forming water droplets. Water, condensate, dew and fog are all coming from cooled down air, where the water-vapour is expelled.

Depending on the relative humidity of the air at the start of the cooling down, the temperature when the air starts forming the condensate differs. This point we call the dewpoint.

All this humidity is sucked into the compressor. The air heat up by compressing it and can easily absorb all the water-vapour. The problems starts when the compressed air is cooling down, and starts forming condensate. Often this is in your pressure vessel, but when you let the warm air flow right into your tyre, it will condensate there.

Water is damaging lubrification, causes corrosion, make dust and rust clogging together and will break components when it starts freezing. So, by cooling down the compressed air with a refrigerated dryer you can force the water-vapour to become condensate and filter this condensate out to make your compressed air dry.

Filtering
We mentioned rust and dust so be aware you also need filtration to keep your compressed air clean. For compressed air components a filtration level of 5 – 20 micron is required, obviously with the required flow capacity.
