Tough and durable, built on the industry-standard G3300 platform and equipped with technology that brings performance, uptime, and low operating cost to your operation. G3306B engines meet the most demanding continuous duty gas compression applications with virtually no unscheduled downtime. Ideal applications for G3306B engines include gas lift, gas gathering, and wellhead gas compression. Cat G3306B gas engine. Ratings: 108-157 bkW (145-211 bhp) @ 1800 rpm are NSPS site compliant capable with Caterpillar or customer-provided air-fuel ratio control and aftertreatment. Engine Design
- Tough and durable, built on industry standard G3300 platform - Caterpillar supplied air/fuel ratio control and threeway catalyst designed specifically for this engine to provide superior emissions control with NSPS and NonAttainment zone compliance - 0.5 g and 1 g NOx settings available - Integrated operator interface panel, TWC and AFRC reduces hands-on time with the engine - Operator interface panel allows setup and servicing without a laptop - Runs on a broad range of fuels and speeds at any emissions level - Factory installed components with single connection point eases packaging Advanced Digital Engine Management
The ADEM A4 system represents the next generation of engine management systems while reducing the number of mechanical components and easing troubleshooting. Features include: • Air/Fuel Ratio Control (AFRC) • Electronic ignition • Electronic governing/speed control • Start/stop logic • Engine protection & monitoring Full Range of Attachments
Large variety of factory-installed engine attachments reduces packaging time Gas Engine Rating Pro (GERP)
GERP is a PC-based program designed to provide site performance capabilities for Cat® natural gas engines for the gas compression industry. GERP provides engine data for your site’s altitude, ambient temperature, fuel, engine coolant heat rejection, performance data, installation drawings, spec sheets, and pump curves. Product Support Offered Through Global Cat Dealer
