Tier 4 Final Engine Integration

CLS, along with Cummins Engine Company and Cummins Power Products, worked together to design a new Tier 4 final Cummins QSX-15 engine power unit. This engine had to have the ability to fit into our signature line of booster compressors, and meet the stringent future emissions regulations imposed by the federal government and EPA on Diesel engine exhaust and particulate. CLS chose early on to utilize our EPA TPEM flex engine credits, and to strategically skip the IT4 emissions step. This strategy allowed our company to focus on the long-term emissions solution design, rather than wasting design time and valuable resources on the interim IT4 emissions solution. The CLS and Cummins team mission was to produce a power unit that could operate with quality, performance, and efficiency, while minimizing the effects on our CLS customers with respect to the overall changes to the engine and its accessories. This project started in February of 2013, with design, and went into production on a Signature Series WB-12 Booster in June. The unit was assembled and began its testing phase in late August/early September. Upon the completion of the testing, the unit received the honor of getting a shiny coat of CLS rental-fleet-green paint. So with that, we welcome Unit # 608 to our rental family. It is now ready for our customers to use in the field. It is of great significance that our company was chosen to work on this project with Cummins, and that we have successfully completed the equipment with this new technology-- affecting off-highway Diesel engines. This project has again shown our commitment to the environment, as well as the technology that protects it. Our people and our products continue to lead and shape the future of the compressor business.
