New modules promise high productivity
A new range of OEM compressor modules from Atlas Copco are said to be tough operators that are designed for durability.

Atlas Copco has introduced a new range of compressor modules for OEM (original equipment manufacturers) manufacturers and drilling contractors, which promises increased drilling efficiency, improved penetration rates and hence higher productivity.
The latest OEM compressor modules operate at higher pressures – of up to 30 bar - and with increased capacities, of up to 600 l/sec (1275 cfm), a spokesman for the Belgium-based manufacturer says.
The new compressed air modules are specifically designed to meet the demands of all types of drill rig operations, including water wells, oil, gas, reverse circulation and blast holes as well as tasks such as pile driving, he says.
“Top of the range is the new XRV 12,” the spokesman points out. “This can deliver up to 600 l/sec (1,275 cfm) at up to 30 bar, while the XRV 10 capacity is 480 l/sec (1,000 cfm) at the same pressure.
“The compact size, reliability and versatility of the Atlas Copco OEM compressed air modules ensures high-quality performance, whatever the conditions. The modules are designed for durability and can operate in the toughest environments.
“The combination of pressure and air delivery rate is flexible, ensuring maximum productivity and versatility. The units can be adapted to meet specific needs in terms of air pressure, free air delivery and inlet speed. This ensures reduced energy bills.
“They can deliver compressed air at any pressure between 15 bar and 30 bar with volumes from 220 l/sec (1000 cfm) (XRV 10) and 250 l/sec (1275 cfm) (XRV 12). Atlas Copco can also build customised compressed air modules to perform specific tasks, he adds.
Compression efficiency is maximised thanks to Atlas Copco’s patented asymmetric screw profile compression system. At the heart of the machine is an oil-injected rotary screw compressor, which can be powered by virtually any power source on a drill rig, truck or other vehicle.
The spokesman continues: “Both top OEM models are delivered as two modules: the compressor and the pressure vessel. This gives added flexibility, allowing them to be positioned to suit the available space. In addition, the frame has forklift slots for easy positioning.”
Setting up of the units is said to be simple, as connecting the system to the drive power source gives immediate access to a continuously regulated, dependable supply of compressed air.
Modules are tested before shipping, to safeguard trouble-free installation and operation, says the spokesman, and Atlas Copco’s commitment to quality at every level ensures a long and reliable service life.
“Particular attention has been paid to making the units easy to maintain and operate. Servicing is simple, with easy access to all key components. Oil filters and oil draining points – and less frequently serviced points – are reached through large removable side panels. All fluids can be easily drained.
Daily service points such as air filters can be accessed without removing any of the canopy panels, while a service door provides access to the cooler compartment for cleaning.
“Safety features are incorporated into the modules. In the unlikely event of a malfunction, such as overheating, the unit will shut down automatically avoiding potentially costly damage,” he says.
Other features include two-stage heavy-duty air filters with safety cartridges, a modified high-pressure stage which extends the module’s life when operating at high capacity and pressure, a Zincor canopy and an IP67 electrical connection.
The new unit complements the range of the smaller single-stage PTO (power take-off) compressors. The XAH2 has a peak delivery rate of 190 l/sec (400 cfm) at its lowest pressure of 3.5 bar, through to 120 l/sec (255 cfm) at 12 bar. Its larger sister model, the XAH4, can deliver up to 550 cfm at 5 bar and 530 cfm at 14 bar.
Both are simple to install as they are shipped in a ready-to-use package complete with all components. They just require connection to the drive power source for instant access to a continuously regulated, dependable supply of compressed air at a specified capacity and pressure, the spokesman says.
