The DrillAirX28 provides improved versatility and drilling speed in addition to a new engine, enabling users to drill two 200-metre holes in a single day at 30 bar of pressure.
The X28 has a nominal flow of 28.3 square metres per minute, but crucially has a pressure rating of 30 bar, manufacturer Atlas Copco said in a press release. As the X28 is designed for geothermal drilling where back pressure is typically higher than in water well drilling, the additional five bar of pressure helps to overcome this while giving enough flow to drive the hammer. The DrillAir X28 comes with Dynamic Flow Boost as standard, providing additional air when the compressor is working at lower pressures. Users are provided with 30 square metres per minute at 25 bar, 31.6 square metres per minute at 21 bar and a maximum flow of 33 metres squared per minute at 16 bar, which leads to faster drilling completion rates, the company said.
“The X28 is designed to balance the relationship between pressure and flow and for the compressor to find the right combination for the application,” said Dmitry Karablinov, product marketing manager at Atlas Copco Portable Energy. “By equipping the compressor with DrillAirXpert technology, users can accurately set the air output based on their drilling requirements, helping to reduce fuel dependency.”
The DrillAirXpert performance management system is fully electronic and freeze-resistant to help ensure it can be deployed in the harshest of environments. The compressor features a 13-litre Scania engine, compliant with stage IV emissions standards. With a large fuel tank and a focus on efficiency, the compressor is capable of running multiple shifts before refuelling.
The DrillAir range is built around the principles of pressure and flow with a design ethos that focuses on the relationship between these two variables. By using a combination of these two variables, the DrillAir range helps users achieve the maximum air flow at any pressure setting.
