The new system allows savings of fuel, tyres, time and CO2.
There is a close correlation between tyre and cost pressure: even minimal pressure differences caused by constantly changing temperatures, load and road conditions increase fuel consumption and tyre wear. How an intelligent tyre pressure control system saves costs was tested by BPW in practice with transport companies.
For a three-axle vehicle with a mileage of 120,000 kilometres (75,000 mi) per year and an average pressure deviation of 10 per cent, AirSave delivers a cost benefit of 700 euros per year – solely as a result of the fuel savings (around 250 litres) and the longer service life of the tyres. At 200,000 kilometres (124,000 mi), the cost savings increase to almost 1,000 euros. And they do so year after year. The gains in time and safety have not yet been factored into this calculation. The driver no longer has to constantly check and readjust the tyre pressure on the trailer one at a time. AirSave thus also reduces the risk of tyre bursts, which can lead to considerable downtimes or even serious accidents. If the tyre pressure drops rapidly because of damage, AirSave alerts the driver and allows an immediate planned stop in the workshop. The telematics network is already prepared in the factory by BPW. In this way, it is not only the driver who is always informed about the tyre pressure via the smartphone app. The authorised agent can also be informed automatically just in case.
The system uses the existing trailer pneumatics and, with a fully automatic booster pump, ensures that the preset tyre pressure is maintained at all times. The air is guided through the axle beam to the wheel end and from there to the tyre valve. The system will uncover a consistent loss of pressure. AirSave kicks in at a pressure deviation of just 0.2 bar – making it more reliable than other tyre pressure monitoring systems. AirSave is maintenance-free for three years.
The system can be connected digitally. An optional connection to the "cargofleet3" telematics portal from idem telematics is fitted by the manufacturer. The driver can keep an eye on the condition of all tyres at all times via the corresponding smartphone app. The app also indicates whether air has been readjusted. Vehicle operators can order the AirSave system ex works directly from their preferred vehicle manufacturer. Source
