Doosan Portable Power has a well-established presence in generators and air compressors, clocking about 30 years’ worth of experience in the former and building on the 140-year legacy of Ingersoll Rand in the latter, thanks to Doosan’s 2007 acquisition of its utility and attachment units. Doosan thus has decades of experience in both and an inherited history of innovation in air compressors dating back to 1871.
In generators, Doosan boasts models ranging from 20kVA to 500kVA, and at Bauma, the brand launched two new units: the G400 with a Scania DC13, capable of producing 400 kVA prime power, and the G500, with a Scania DC16 and 500 kVA prime power.
Kevin Zimmer, vice president for portable power at Doosan, notes: “The generator business is one that Doosan has been in for many years, and we’re now looking to take this product forward in the Middle East region, which has been a growing market for us.
“In this market, we’re fully committed to working through both the challenges and the opportunities that we have — as you’re seeing with the new generator product line.”
Doosan’s compressor range is meanwhile one of the most comprehensive for the Middle East, and includes a strong selection of high ambient models, including the 7/26E HA, 7/31E HA, 7/41 HA and 7/53 HA models, with free air deliveries from 2.0 to 5.0 m3/min and a rated operating pressure of 7 bar (100 psi).
“These small compressors are aimed at a very wide range of applications in plant hire, construction and general industry, including standard pressure applications such as powering breakers and tools in road repair, demolition and refurbishment.” says Zimmer.
The 7/26E HA, 7/31E HA, 7/41 HA and 7/53 HA models offer a number of important options, including an integral 6 kVA generator, which allows the units to supply an electrical output in addition to compressed air. As a result, electric tools or other electrical equipment such as lights and welding systems can be run in parallel with pneumatic equipment. The smaller portable compressors can also be equipped with a ‘bunded base’ to ensure that all operating fluids (fuel, oil and water) stay within the compressor.
The small compressor range is part of a complete line of portable compressors from Doosan Portable Power comprising 24 different models, with free air deliveries between 2.0 and 45.0 m³/min and operating pressures between 7 and 35 bar, and a modular design that ensures a wide range of optional equipment can be added easily.
Zimmer highlights: “The biggest thing you have to be careful of here, whether it’s with a generator or an air compressor, is the ambient temperature — balancing the cooling capacity that you have with what the customer wants in terms of the working output and the noise.”
This is doubly the case with regards to air compressors, where you’ve got two elements to cool — the compression end and the engine.
Zimmer continues: “In other parts of the world you want a really nice small package, but you can’t get that with the region’s kind of ambience — you have to build it accordingly — and that’s where the years and years of experience come in: in being able to quieten these machines down without affecting the cooling.”
In terms of the Doosan process, every product is tested at three stages: at the development table, during production and in application. Zimmer explains: “A lot of our testing is done in the chamber environment, because we want to test up to 50° morning to night, and there we can control that. In fact, we can even introduce moisture into some of our chambers — so a lot testing takes place before we even send it anywhere for sales or even live testing.”
Ultimately, the decision is the customer’s, but Doosan is nothing if not prepared.
