Unlocking SA’s Development and Economic Potential

variables to improve drilling efficiency through the most efficient use of compressed air, ultimately dramatically reducing fuel costs. What sets these two compressors apart is their advanced Pace and DrillAir AirXpert technologies, which are simple to use and place drill operators firmly in control. Pace (Pressure-Assisted through Cognitive Electronics) is a dynamic optimisation feature, which allows the user to tap into the compressor’s electric engine to control pressure and flow. Being able to match flow and pressure to their application requirements now eliminates the need to have two separate machines.

Performance management system

DrillAir AirXpert furthermore offers up to 30% improved drilling speeds. This performance management system includes software (Dynamic Flow Boost, Dynamic Control and XPR), as well as a LED hardware controller (Xc4003), electronically controlled inlet valve and a variable minimum pressure valve. The Dynamic Flow Boost provides up to 4m³ a minute additional flow when flashing and during drill stem refills. In addition, it gives 10% more flow at lower working pressure for large diameter drilling. The key benefits include quicker flushing, faster drill stem refill, and a shorter time to complete drilling. “Atlas Copco’s XPR (Extended Pressure Range) extends the working pressure range while setting it as low as 21 bar. In addition, the FuelXpert

system ensures fuel efficiency and partial load with an additional fuel filter for better engine protection,” he explains. “The combination of DrillAir AirXpert technology, the Atlas Copco screw element and the Cummins Stage III engine provides high efficiency for a wide range of pressure and flow settings,” Craig adds.

Simple maintenance

With its 500-hour service intervals, the compressors offer customers trouble-free service, quick and simple maintenance and low operational costs. The machines’ centralised drain and air filtration systems facilitate easy servicing; while the design of the new oil separator system reduces maintenance time by over an hour.

A dedicated service door allows for convenient oil level observation and oil filling. A three-layer coating on the body of the machine offers an extended life of corrosion-free service, further contributing to lower operational costs. “Our new compressors have been chosen for their robustness, and the fact that they are therefore wellsuited for use in remote and harsh environments, where support is sometimes hard to access,” Craig concludes.
