Bauma Preview: Doosan portables to make debut at show
Doosan Portable Power will be showing the new 21/220 and 25/280 large Stage IIIB portable compressors and new G80-IIIA (80 kVA prime power) and G100-IIIA (100 kVA prime power) generators for the first time
The new G80-IIIA G100-IIIA (100 kVA prime power) gens meet the latest EU Stage IIIA engine emission regulations
Doosan Portable Power will be showing the new 21/220 and 25/280 large Stage IIIB portable compressors and new G80-IIIA (80 kVA prime power) and G100-IIIA (100 kVA prime power) generators for the first time.
Large portable compressors such as the new 21/220 and 25/280 models are used to provide compressed air for a wide range of drilling and boring machines for quarrying, mining, site investigation, geothermal, mineral exploration, water well construction and shallow oil and gas projects, together with truck-mounted applications for quarry and water well drilling. They also cover other specialist applications such as abrasive blasting, spray painting and standby and temporary compressed air for industry.
The 21/220 model is powered by the Cummins QSL9 engine providing 254 kW (340 HP) of power at 1800 RPM and using Exhaust Gas Recirculation (EGR), Diesel Oxidation Catalyst and Diesel Particulate Filter technologies to meet the Stage IIIB regulations. The 21/220 compressor produces a free air delivery of 21.5 m3/min at an operating pressure of 21.0 bar. The 21/220 model is part of a new family of large Doosan portable compressors based on a common platform that also includes the new 9/275, 9/305, 12/250 and 17/240 models and offers free air deliveries from 21.5 to 30.0 m3/min at operating pressures from 8.6 to 21.0 bar.
The 25/280 compressor has a free air delivery of 28.3 m³/min at a rated operating pressure of 25.1 bar. It is powered by the CAT C-13 diesel engine using cooled EGR with the Cat Clean Emission after-treatment system to meet the Stage IIIB regulations. The CAT C-13 engine provides 354 kW (475 HP) of power at 1800 RPM. Dual pressure regulation is a standard feature of the new 25/280 compressor, allowing it to supply compressed air at operating pressures of either 25.1 or 17.2 bar. Dual pressure regulation expands the scope of applications for the 25/280 compressor.
