Superior* SGTD Engines
Hit the sweet spot for medium-speed gas drivers
GE Oil & Gas
Superior Engines Since 1889
The Superior brand name has a long-standing reputation for high
quality engine and compressor products, dating back to 1889. Since
1976 alone, more than 10,000 Superior engines and compressor
frames have been manufactured and installed worldwide in a
variety of high- and medium-speed applications.
Superior turbocharged gas engines are medium-speed and built
for continuous, heavy-duty service. Optimal fuel/air mixing in
the cylinder, timed fuel injection, and air-charged intercooling
result in reduced fuel consumption and lowered emissions. The
low compression (8.75:1) pistons keep dynamic stresses at a
conservative level, provide for more stable operation and enhance
engine tolerance to variations in quality of fuel.
The conservative horsepower rating of Superior engines provides
ample reserve for emergency situations. Intercooling with optimal
valve overlap results in cooler combustion chamber parts while
assuring lower fuel consumption, greater efficiency, longer service
life and trouble-free operation.
Superior SGTD 12- and 16-cylinder gas engines
reach peak power and efficiency when packaged
with Superior MH, WH or WG separable
compressors operating at 900 RPM.
GE Oil & Gas offers a wide range of compressor solutions for your
unique gas applications. All of our Superior compressor packages are
designed for application flexibility and engineered to provide rugged,
reliable service and value.
