Doosan launches largest single-axle unit
01 October 2009
DOOSAN Infracore Portable Power (DIPP) is set to launch its largest single-axle portable compressor, which boasts the “highest levels of durability, productivity and serviceability”, according to the company.
The new 12/150 model offers outstanding towing stability for transport behind a vehicle and incorporates the ‘built to be used’ design common to all DIPP compressors.
“The 12/150 has a free air delivery of 14.9 cu m per min (526 cu ft per min) at an output pressure of 12 bar and is designed for applications in plant hire, construction, quarrying and general industry,” says George Schmalzried, a spokesman for the company. “This encompasses not only standard pressure applications such as powering breakers and tools in road repair, demolition and refurbishment, but also more specialist uses including drilling, abrasive blasting, spray painting, optical fibre blowing and standby and temporary compressed air for industry.”
The 12/150 offers as a standard feature a bunded base for environmental protection and well-positioned fuel tanks, featuring large-size fillers, also limiting the risk of fuel spillage. The central drains contribute to the excellent serviceability of the 12/150, with all areas carefully designed for ease of inspection, maintenance and repair, he says.
In addition, service intervals for different compressor components have been rationalised to reduce associated costs for the customer and increase utilisation.
It is powered by the Cummins QSB 6.7 FR91440 six-cylinder diesel engine providing fuel efficiency, quiet-running, easy maintenance and high reliability and durability required for this application, Schmalzried says.
The Cummins diesel engine is water-cooled and has a power output of 164 kW (220 HP) at a full load speed of 2,000 rpm. The 12/150 has a standard LAT (limited ambient temperature) of 46 deg C.
As well as these options, the highly modular design of the new compressor allows other types of optional equipment to be added easily. In this way, the model can be adapted for specific applications, such as fitting an aftercooler and water separator system for abrasive blasting. An optional diesel engine exhaust spark arrestor is a basic but key safety feature for hazardous area applications and should the engine begin to accelerate due to volatile vapours in the atmosphere, an optional overspeed valve closes the air intake to the engine, to prevent damage due to overspeed, he states.
The compressor has an intuitive, simple key-start sequence, said to be ideal for rental companies because of the reduced risk of machine abuse by untrained operators, while a friendly control panel offers an open layout of instruments and warning indicators.
