Project Background

The Maintenance Manager at the Hereford site was becoming increasingly concerned about the frequent damage caused by liquid water in compressed air lines. In particular the air controllers in the boiler room were in constant need of replacement. In a matter of weeks, the air controller could be replaced up to 5 times, costing the site £1,500 to replace each time.

The Heineken site urgently needed a real solution to this expensive problem.

Why did Heineken choose Expel?


EXPEL is a high efficiency compressed air filter which uses computational fluid dynamics to continually pass all liquid water, oil emulsion fluids and solid particulates down to 1 micron through the unit and into an AVG Auto Drain. This means that the performance of Expel does not drop with use and remains 99.999% efficient and does not require any replacement filter elements or maintenance to operate.

In contrast, conventional compressed air filters simply retain the substances they collect, so the performance of these filters deteriorates as they are used. This is exactly how harmful substances reach pneumatic equipment and cause expensive damage.

After hearing about the exciting money saving and equipment protecting qualities Expel can offer, the Maintenance Manager was quick to take action and decided to install Expel.
