requirements or achieves even better performance or, better still, both.

Even more important, AJAX customers are never alone.

2 Sole-source responsibility that s as good as our name. Since 1877, the AJAX brand has been synonymous with exceptional quality, absolute dependability and unbeatable performance. Our customers know that an AJAX innovation is a true innovation, one that helps meet the most stringent compliance requirements or achieves even better performance or, better still, both. But one that never comes at the expense of an already RAISING PERFORMANCE. TOGETHER proven superior product design. Even more important, AJAX customers are never alone. We re with you every step of the way from initial planning and purchase to installation and field service. The engineering support of Cameron only adds to the equation. In the last four years alone, Cameron has made a committed, multi-million-dollar investment in AJAX, with impressive results you ll see here, with much more on the horizon. There s never been a better time to put the AJAX team to work for you.

3 Gas Engine Compressors Exciting New AJAX Engineering Evolutions TUNED EXHAUST EXPANSION CHAMBER Because ever-tightening environmental requirements pose such difficult, constant challenges, our goal is to help you comply without giving up performance. Our patented exhaust expansion chamber provides perfect proof. Its ingenious design allows you to recover up to 50% BHP derating, reduce NOx by 60%, or both, depending on your needs. Even better, there are no moving parts, no computers and no air-fuel ratio controllers, and no maintenance is required. OXIDIZING CATALYTIC CONVERTER Many try, but only AJAX delivers a highly successful, field-proven catalytic converter to meet the new environmental guidelines for two-stroke low-emission gas engines. Designed to alleviate the potential worries of oil contamination and pressure spikes, this new product improvement virtually eliminates CO and VOC emissions and greatly reduces formaldehyde emissions. Add this to our patented expansion chamber, and it s possible to achieve any combination of these benefits, including reduced NOx and/or increased site horsepower ratings. ELECTRONIC GOVERNING SYSTEM AJAX engineering comes through in another big way with our integrated governor throttle body, now standard equipment on AJAX engines. The IGTB provides excellent speed stability and quick response to load changes. The governor measures engine speed with a magnetic pickup and automatically adjusts fuel gas header pressure as required to maintain desired speed. The IGTB offers the features of simplicity without the requirement for on-site tuning. FLEXIBLE FUEL HEADER This simple design just makes good sense and saves money. By providing easy access, our new flexible fuel header lets you maintain fuel valves, and even replace them, in a matter of minutes. As an added benefit, the system relieves much of the assembly stress from the gas injection valves. LUBE SYSTEM For even better reliability, we ve made a sophisticated divider block system standard issue for our power and compressor cylinders. A solid-state flow monitor provides automatic low- and no-flow shutdown to prevent damage to the engine in the case of pump failure. With fewer moving parts, less tubing and only a few pumps required, the system is a model of userfriendly efficiency.

5 Simplicity, Durability Value for Years to Come Simplicity reigns supreme with AJAX integral technology. And improvements are made with one very critical parameter in mind never compromise the strength and simplicity of the original design. That explains why our integral engine-compressors simply last longer, cost less to maintain and come standard with features that meet all the BACT emissions requirements. They also consistently maintain an impressive 98% or better availability. For a life-cycle that can easily span 50 years or more, all that s required of you is an annual oil change and very few special tools; as proof, our very first two DPC models, built in 1958, are still running strong.

6 The AJAX Competitive Advantage BETTER PRODUCTS. After 50 years of reliable, efficient, long-lasting service, AJAX integral engine-compressors continue to earn their distinguished reputation for being as close to worry-free as any compressor product in the world. Our product line, from 147 to 845 horsepower ( kw), and a cylinder line-up capable of handling a wide range of pressures, from vacuum to 5500 psi (379 BAR), offers up to six ratios capability and the lowest BHP per million flows for a wider range of applications, including sour gas. Thanks to its unique two-stroke design, the AJAX integral engine-compressor virtually eliminates problems typically caused by the presence of sour gas, handling H 2 S content up to 3.0 mol%.
