LAS VEGAS, Nev. (October 26, 2010) - Hobart today is demonstrating a new Tier 4 Interim ground power unit ahead of the 2011 emissions requirements, at the International Airport Expo. The 140-kVA unit features a Cummins QSB6.7 engine, supplied and machine-integrated with the support of Cummins Bridgeway, achieving a 10 percent fuel-efficiency improvement compared with the Tier 3 model. Beyond meeting the new emissions regulations, the new model, available for order on Jan. 1, 2011, has updated controls and features and has undergone extensive testing, both in factory test labs and in the field.

Ground power equipment is used to power aircraft while they are parked at the gate, and in some cases is used to start the aircraft engines. Ground power equipment includes, at a minimum, a base engine coupled to a generator with an appropriate control system, cooling package, air intake and exhaust system.

“Hobart units range from 60 kVA to 180 kVA and are used all over the world. The new 140CU20 unit, on display in Hobart Booth #2414, is powered by Cummins Tier 4 QSB6.7 and meets EPA and California ARB Tier 4 Interim
regulations. The new regulations for 2011 for the 174 to 751 horsepower range require a 90 percent reduction in Particulate Matter (PM) and a 50 percent reduction in Oxides of Nitrogen (NOx),” said Bill Bamford, Vice President – General Manager of Hobart.

Field Tested And Validated For The Future
Field-testing on the 140CU20 showed impressive results. Beyond the lower cost of operation, field test operators and maintenance technicians noted that their work environments were improved with the new unit. These improved work environments are a result of the reduced exhaust emissions and crankcase ventilation emissions for the Tier 4 Interim regulations. The new 140CU20 also features a more durable and user-friendly control panel for all weather conditions.

“This new 140CU20 unit is proof of our ability to meet industry demands for proven applications of future technology. Hobart has tested this new unit in the field with end users and has had exceptional results. In addition to the emission reductions for 2011, our work with Cummins and its Tier 4 technologies also allow our customers to achieve up to 10 percent fuel economy improvement compared with our previous models, depending on rating and duty cycle,” continued Bamford.

The 140CU20 unit is the first in a new range of next-generation equipment offered by Hobart to meet U.S. EPA Tier 4 Interim and European Stage IIIB offhighway emissions regulations that will take effect in January 2011 for units from 174 horsepower (130 kW) to 751 horsepower (560 kW). The same size unit will have a complete range of power from 120 to 180 kVa.

Hobart And Cummins Partnership For Tier 4
Cummins Bridgeway, a distributor of Cummins Inc., partners with Hobart to integrate and validate Cummins products in Hobart equipment. This work ensures that Cummins and Hobart optimize and deliver the most dependable solution with the lowest cost of ownership.

Hobart and Cummins Bridgeway have a partnership of over 20 years, which ensures that this new product line builds upon the proven durability and reliability of Cummins engines. Hobart started working with Cummins in 2007 on the new Tier 4 Interim product line by ordering a prototype engine, attending multiple Cummins Tier 4 seminars and developing and validating engineering specifications immediately.

Cummins has a unique advantage in that it has designed and manufactured the critical engine subsystems and exhaust aftertreatment. The Tier 4 Interim units are integrated with the engine, using both a Cummins Particulate Filter for the 90 percent PM reduction and Cummins Direct Flow™ air cleaner system by Fleetguard. Cummins Tier 4 products also have improved engine response with the Cummins VGT™ Turbocharger. Hobart has minimized the size of the new unit by using the Tier 3 model’s
framework and its patent-pending cooling system, thus not allowing the radiator to dictate the package size. Also optimizing installation space, the Cummins Particulate Filter replaces today’s Tier 3 mufflers with the same sound attenuation, ensures ultra-clean operation and eliminates elemental black carbon. The Cummins Direct Flow provides the same or better air cleanliness
protection in a smaller space claim.

Installation Checks And Application Tests
Hobart and Cummins make sure every piece of equipment meets the highest levels of installation checks and tests. As part of Hobart’s success in the ground power unit business, Hobart has embraced and appreciated Cummins ensuring that its products meet the most stringent installation quality audits. Hobart also uses Cummins application engineering bulletins for design and validation, and this Tier 4 Interim product was no exception.

Hobart and Cummins have been working to meet or exceed the airline industry’s stringent operation and emissions requirements and expectations of a ground power unit. This work and continued partnership will continue to allow Hobart to provide products and solutions through the Tier 4 Interim and Final emissions standards changes in the next 10 years and beyond.
