The complete combination with coolant compressor, condensor and heat exchanger will cool down the compressed air so it will condensate and keeps your system free of corrosion, clogged dirt and damage during freezing periods.
Strongly advised for customers who require compressed air with a very low dewpoint for working in very low ambient temperatures, or with sensitive pneumatic components.
• Plug-and-play
• Low maintenance
• Optional mounting onto the air compressor frame
• R134a coolant. Optionally R1234yf for GWP 4

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.
• 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

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.

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.
• 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

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.
• 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

Well over 65% of our turnover is OEM supplied. Q Plus has served the Benelux agricultural OEM in the past 15 years with components for Tyre Inflation Systems.
The recent redesign of our tyre inflation components has led to a complete Q Plus Tyre Inflation System as we present it here, and which is primarily dedicated to the OEM.
This new tyre inflation system development also resulted in the founding of a dedicated company for Tyre Inflation Systems: QTIS B.V.

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.
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.
