Parker domnick hunter’s PNEUDRI compressed air filtration system for Johnson Matthey
domnick hunter PNEUDRI with dewpoint dependent switching
Compressed air filtration systems, designed to meet rigorous Australasian and international air quality standards for manufacturing and metal working, have been adopted by a precious metals specialist to halve its energy costs.
Johnson Matthey, based in Royston, United Kingdom, 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 are important for Johnson Matthey. Parker domnick hunter, also known as domnick hunter , provided a solution.
Parker domnick hunter’s Business Development Manager, John Davis says that Parker domnick hunter offered the ideal solution by replacing the existing twin tower dryers with a domnick hunter PNEUDRI complete 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 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; "Our initial selection of domnick hunter PNEUDRI was based on the compact size of the dryers. PNEUDRI was easily integrated into our existing compressed air system. We also required a system which could be maintained easily.
"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".
