Vilter's line of single-screw compressors for
natural gas and process applications (VSG¢â) is used in a variety of applications,
including digester gas, fuel gas boosters, landfill gas, LNG boil-off,
vapor recovery, process gas and natural gas gathering.
These compressors have been designed with efficiency
and versatility in mind, providing both performance and maintenance advantages.
The key is in the balanced design. The positive
displacement rotary compressor uses a single main screw intermeshed by
two opposing gaterotors. Gas compression occurs when the individual fingers
of each gaterotor sweep through the grooves of the main screw as the screw
rotates. Fewer moving parts means fewer overhauls resulting in significant
The balanced main screw results in ultra-low bearing
loads and significantly decreased vibration and sound levels.
In addition to supplying the bare compressor,
you can also count on our team of engineers to design and manufacture complete
packages for the natural gas and process industries.
