The line of G3500B engines brings versatility, uptime, and low operating cost to your gas compression operation. They deliver the lowest engine-out emissions in the industry without sacrificing performance. Ideal applications for G3500B engines include gas lift, gas gathering, and wellhead gas compression. Cat G3520B gas engine. Ratings: 1104-1286 bkW (1480-1725 bhp) @ 1200-1400 rpm are NSPS site compliant capable.
- Built on G3500 LE proven reliability and durability - Ability to burn a wide spectrum of gaseous fuels - Robust diesel strength design prolongs life and lowers owning and operating costs - Broad operating speed range at lower site air densities (high altitude/hot ambient temperatures) - Higher power density improves fleet management - Quality engine diagnostics - Detonation-sensitive timing control for individual cylinders
Ultra Lean Burn Technology (ULB)
ULB technology uses an advanced control system, a better turbo match, improved air and fuel mixing, and a more sophisticated combustion recipe to provide: - Lowest engine-out emissions - Highest fuel efficiency - Improved altitude and speed turndown - Stable load acceptance and load rejection
- Meets U.S. EPA Spark Ignited Stationary NSPS emissions for 2010 and some non-attainment areas - Lean air/fuel mixture provides best available emissions and fuel efficiency for engines of this bore size
Advanced Digital Engine Management
ADEM A3 engine management system integrates speed control, air/fuel ratio control, and ignition/detonation controls into a complete engine management system. ADEM A3 has improved: user interface, display system, shutdown controls, and system diagnostics.
Full Range of Attachments
Large variety of factory-installed engine attachments reduces packaging time.
Every engine is full-load tested to ensure proper engine performance.
Gas Engine Rating Pro
GERP is a PC-based program designed to provide site performance capabilities for Cat® natural gas engines for the gas compression industry.
