Single-Screw Compressors forNatural Gas and Process Applications
Vilter’s line of single-screw compressors offer unique advantages making
them a perfect fit for natural gas and process gas applications. 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 maintenance savings.
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.
