Energy savings using compressed air filtration system

Compressed air filtration has been adopted by a precious metals specialist to halve its energy costs.

Johnson Matthey, based in Royston, UK, always took the precaution of ensuring its compressed air was constantly clean and dry, but it also wanted a system which could be monitored to constantly appraise energy consumption.

Production efficiency, quality and competitiveness is important for Johnson Matthey, which produces autocatalysts for cars, trucks and motorcycles.

Parker domnick hunter’s business development manager, John Davis, says Parker domnick hunter offered the solution by replacing the existing twin tower dryers with a domnick hunter Pneudri with dewpoint dependent switching.

The DDS system operates by continuously testing and measuring the outlet air quality (or dewpoint) of the dryer and adjusting the duration of the desiccant chambers’ drying and purging cycles to suit variable operating conditions. The fewer cycles the machine goes through in an hour, the less energy it demands.

Colin McKay, chief engineer at Johnson Matthey, commented: “domnick hunter was also able to offer an energy management system which allows us to constantly monitor the efficiency of the compressed air purification process and has led to major cost reductions. Johnson Matthey has experienced typical energy savings of around 57% since the installation of domnick hunter products.”
