Gas Compression Engine OIL AND GAS G3512B

OVERVIEW
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 G3512B gas engine. Ratings: 772 bkW (1035 bhp) @ 1400 rpm are NSPS site compliant capable.

ENGINE DESIGN

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:

Lower environmental impact

Higher return on investment

Lower operating costs

Higher workforce efficiency

EMISSIONS

Capable of meeting 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.

TESTING
Every engine is full-load tested to ensure proper engine performance.

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.
