Atlas launches new geothermal drill compressor

Atlas Copco has expanded its DrillAir range with a new geothermal drilling compressor.

The new DrillAirX28 is designed for greater versatility and drilling speeds.

According to Atlas Copco, it features a new engine and allows operators to drill two 200 metre holes in a single day at 30 bar of pressure.

The X28 compressor has a nominal flow of 28.3 cubic metres per minute, with a pressure rating of 30 bar.

“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,” Atlas Copco said.

It has Dynamic Flow Boost as standard, which provides additional air when the compressor is working at lower pressures, resulting in users being provided with 30 m3/min at 25 bar, 31.6 m3/min at 21 bar and a maximum flow of 33 m3/min at 16 bar for faster drilling completion rates. 

“The X28 is designed to balance the relationship between pressure and flow and for the compressor to find the right combination for the application. By equipping the compressor with DrillAirXpert technology, users can accurately set the air output based on their drilling requirements, helping to reduce fuel dependency,” Dmitry Karablinov, Atlas Copco Portable Energy’s product marketing manager, said.

The DrillAirXpert performance management system is completely electronic for increased accuracy.

It features a 13 litre, stage IV emissions standards compliant, Scania engine, and has a large fuel tank which allows it to run multiple shifts before refuelling.
