Specifically designed for geothermal drilling applications, the DrillAir Y35 offers significant increases in drilling rates, fuel efficiency and reliability thanks to its 35 bar pressure and 34.8 m3/min (580 l/s) flow.
“ The DrillAir Y35 reduces the time and associated costs of geothermal drilling, representing a new benchmark in portable drilling efficiency. Lower maintenance costs, less fuel consumption, increased uptime and faster drilling all make a positive contribution to a driller’s bottom line. ”
The DrillAir Y35 makes it possible for operators to drill both faster and deeper. Thanks to its 35 bar working pressure, drilling depths of 500 metres per day are achievable. One reason for this is the Y35’s integrated Dynamic Flow Boost technology that can be used to increase flow from 34.8 to 39m3/min (650 l/s), providing faster flushing and stem refill and ultimately a quicker finish time. When required, the working pressure range can also be set as low as 15 bar with Atlas Copco’s patented Extended Pressure Range (XPR) technology. This helps prevent soil cavitation during overburden drilling, as well as enabling the same compressor to be used for both geothermal and foundation drilling.
The new compressor includes a reliable Scania engine that is compliant with Stage IV emission standards** for non-road engines. The DrillAir Y35 meets all the latest environmental standards, and is a low noise machine making it suitable for construction projects in built-up urban and residential areas. Other features including a built-in oil cleaner, saver ring and separate cylinder heads, contribute to an extended service life.
The DrillAir Y35 was designed and built for reliable performance. A three-layer coating protects all bodywork to increase lifetime and residual value. Ease of transportation played a big part in the overall design of the DrillAir Y35. Its compact dimensions, including a short 4.1 metre compressor frame and lower weight, ensure that a single truck can carry both the compressor and the rig. This also provides for improved manoeuvrability on site.
With the DrillAir Y35, maintenance and repair costs are fixed for the first two years or 4000 running hours with Atlas Copco’s standard warranty package. Service costs can also be fixed for the lifetime of the machine with a range of customisable service plans.
*The DrillAir Y35 consumes less than 2.2 litres of fuel per meter drilled, dependent on various operational parameters.
