Meeting the Drilling Industry’s Demand for Auxiliary Air
A key trend in the types of drilling services is the greater need for fast, deep, large-diameter hole drilling, reports Atlas Copco. Often, on-board compressors just can’t provide the necessary penetration rate and bailing air required for these jobs.
In response, the company’s Compressor Technique business acquired the Hurricane air and gas booster compressor business based in Franklin, Indiana, USA in April 2008, which was integrated with the Portable Air Division. These boosters complement the existing Atlas Copco product range, enabling Compressor Technique to deliver air pressures up to 275 bar, possibly higher.
Then, in November, the Portable Air Division team based in Antwerp, Belgium introduced a new auxiliary range that provides the most powerful air supply available from a portable compressor. Intended primarily for drilling contractors, these machines have also achieved the lowest specific fuel consumption per unit air delivered. The 25 bar (365 psi) XRVS and 30 bar (435 psi) XRXS models in this DrillAir line were launched in November 2008 and the 35 bar (510 psi) XRXY versions in late March this year. Atlas Copco anticipates the main markets for these new compressors will be in the mineral exploration, water well and geothermal drilling sectors and also in oil and gas development.
