Supplying clean, dry compressed air under the conditions dished out by the mining and resources industry is a challenge to any manufacturer, but domnick hunter is succeeding where less robust products might fear to tread.
Its PNEUDRI range of high performance compressed air drying systems is now in service at sites ranging from the desert heat of the Australia Outback to the confined and corrosive conditions on wave-tossed oil rigs.
"One of out latest international applications on oil rigs in the North Sea involved ambient temperatures between -20°C and +30°C, wind speeds of up to 130 kph and waves up to 30m," says domnick hunter's Australian Business Development Manager, Mr John Davis.
The equipment had to function in a corrosive environment with little space (conditions similar to those off the Australian and New Zealand Coasts) - a demanding working environment where the qualities of the PNEUDRI range came to the fore.
Light weight, compact, modular, pneumatically operated Maxi PNEUDRI dryers, skid-mounted with pre and after-filtration, provided the solution to providing instrument quality air offshore for the three operators who were supplied with purification skids. All are delighted with their performance, says Mr Davis.
The latest compact and electronically controlled PNEUDRI MX and MPX systems being introduced to Australia and New Zealand feature patented modular construction that allows for rapid expansion of systems as needs expand, as well as providing 100 per cent standby drying capacity at a fraction of the cost of larger conventional systems.
With aluminium formed towers typically half the size and weight of traditional twin tower designs- taking up less space and making installation easy - the heatless dryers will deliver air at - 40 deg C pressure dewpoint as standard, in accordance with ISO 8573.1 :2001 class 3.2.1.
When combined with domnick hunter's extensive range of filters, the dryers can achieve Air Quality Class 1.2.1 and 1.1.1. Flow rates of individual units extend from 408 Nm3/h to 2815 Nm3/h.
Release of the new PNEUDRI systems in Australia is part of a worldwide product introduction following the global release of domnick hunter's complementary OIL-X EVOLUTION compressed air filters, which use aerospace technology to optimise air flow paths and reduce system operating costs.
