Filter system purifies nitrogen for tyres

Parker Balston, has launched TyreSaver - a compact, self-contained, nitrogen generator based tyre inflation system for independent tyre centres and garages.

TyreSaver supplies nitrogen with the purity required to keep tyres at constant pressure.

Tyre centres and garages will now be able to help British motorists to take advantage of the acknowledged benefits of inflating car tyres with nitrogen rather than compressed air - more comfort and safety, up to 4% savings in fuel costs and up to 30% increase in tyre life.

Over the last few years, the filling of tyres with nitrogen has increased dramatically in popularity in countries such as Germany and Italy where, almost every tyre shop and garage is equipped with a source of nitrogen, for example, heavy gas cylinders.

In Germany, motorists use green valve caps to show they are environmentally aware.

Tyre retailers use nitrogen filling as a value-added sales tool.

Nitrogen has for many years been the accepted gas medium for filling the tyres of aircraft, racing cars and heavy mining and construction vehicles and equipment.

Nitrogen is used for safety reasons and to ensure that tyres are always at a constant pressure.

Nitrogen inflation is recommended where there is a risk of explosion; where high pressures are involved; and where there is the risk of electrical discharge.

Compressed air - the traditional medium for inflating car tyres - contains both oxygen (21%) and nitrogen (78%).

The rubber tyre is like a membrane, through which oxygen permeates three times faster than the nitrogen.

The result is that the oxygen slowly leaks out through the rubber walls, and the under-inflation leads to higher tyre wear with a consequent decrease in safety and comfort, and higher fuel costs.

In addition, the water in the compressed air oxidises the rim causing it to corrode.

TyreSaver is a compact, self-contained nitrogen generator based on Parker hollow fibre membrane technology which makes it possible to separate air into nitrogen and an oxygen-enriched air stream.

Nitrogen, which is dry, can therefore easily be produced from the compressed air source found in all tyre centres, tyre shops and garages.

The system is capable of filling 25 to 30 tyres per hour - similar to a traditional compressed air filling system.

TyreSaver is ready to operate as soon as the compressed air supply is connected and automatically switches on and off depending on the nitrogen demand.

The installation has virtually no moving parts and a high quality compressed air treatment section, resulting in reliable, trouble-free operation with virtually no maintenance.
