Why Liquid Ring Compression for Challenging Gases?

Liquid ring compression is often selected when conventional compressor technologies struggle with wet, contaminated, or hazardous gases. Because the compression chamber uses a sealing liquid, the technology can support cooler operation and tolerate difficult gas conditions. 

NASH liquid ring compressors are frequently used where process reliability, gas compatibility, safety, and reduced maintenance are important selection factors. 

  • Handles wet, saturated, dirty, toxic, and corrosive gas streams
  • Supports demanding applications such as flare gas recovery and VCM recovery
  • Available in single-stage and two-stage configurations
  • Alternative seal liquids can be used when water is not compatible with the process gas
  • Rugged designs support long service life and low maintenance requirements

Built for Demanding Processes

They are used across key applications such as flare gas recovery, vapor recovery, hydrogen and carbon dioxide compression, and VCM recovery.

Simple and Reliable

With a single moving part and no internal lubrication, NASH compressors offer low maintenance and long service life.

Efficient and Flexible

A wide product range with single and two-stage options helps reduce energy use and operating costs.

Trusted Quality

Manufactured to ISO standards and ATEX certified, with over 100 years of experience and global support.
