Vigia Automatic Tire Pressure Systems has revamped its offering for 2013. The new Vigia models incorporate advances in electronics that are said to improve system performance and reliability.

The new Vigia NM253 External System for trucks and trailers features a new and compact display module that makes installation easier. Communication to the driver is improved with alarm sounds that vary with the magnitude of the pressure drop in tires. It has an optional interface for remote monitoring via telematics.

Also available in the new Vigia lineup is the digital NM343. Its display module generates information that’s transmitted via its interface to the truck’s existing satellite module and ultimately to the user’s telematics software. Users can access information on the status of the system anywhere in the world on any computer or mobile device.

For trailers Vigia offers the internal system NM249, claimed to be the only automatic tire inflation system in the market that can be installed in any type of axle. Hollow, reinforced and solid axles, fixed or lift axles, even steering axles can be outfitted with the NM249. Unlike other similar systems, it doesn’t pressurize the axle or hubs. Its rotating valve is placed outside the hub so no pressurized air or contaminants can enter the hub.
