With AirSave, a three-axle vehicle saves more than 700 euros a year.
Truck tyres have to withstand a great deal: load weights, road conditions and temperatures that are constantly changing can quickly lead to pressure differences that will rapidly wear out the tyres. The costs of premature wear alone are enormous. If a tyre blows out, it can have unforeseeable financial consequences due to downtime or even accidents.
According to a British study, 82 per cent of tyre blowouts can be effectively prevented if the tyre pressure is controlled automatically. This is why BPW will soon be offering a robust control system ex works that pays for itself in the first year: BPW’s new ‘AirSave’ system is claimed to deliver a cost benefit of more than 700 euros per year for a three-axle vehicle with a mileage of 120,000 kms (75,000 miles) per year and an average pressure deviation of 10 per cent as a result of the fuel savings (around 250 litres) and the longer service life of the tyres. And this figure does not even include the time, vehicle and delivery interruptions saved. A three-axle vehicle with the AirSave system saves 655 kg (1,444 lb) in CO2 emissions per year, and protects the side of the motorway from the remains of blown tyres.
For its system, BPW relies on a technology that has proven itself on the market and has been further optimised in many respects. AirSave requires no maintenance for three years and always maintains the correct tyre pressure – even if the tyre is damaged, it improves its emergency running properties. 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 displays a permanent loss of pressure. AirSave kicks in at a pressure deviation of just 0.2 bar – making it more reliable than other standard tyre pressure monitoring systems.
The ability to connect to the system digitally is a feature of BPW products: an optional connection to the ‘cargofleet3’ telematics portal from idem telematics is available, which then alerts the dispatcher in the event of pressure loss via the telematics portal. The driver also receives a warning via the cargofleet driver app. In future, AirSave will also be able to be selected at the click of a mouse when ordering running gear via the BPW online configurator.
