Liquid Ring Compressors Market Soars to New Heights: Emerging Trends and Future Growth


Liquid ring compressors are a type of rotary positive displacement compressor that seals the rotating impeller to the stationary casing with a liquid. Water is commonly used, but other liquids or a combination of liquids can also be used. The liquid forms a rotating seal, preventing air, gas, or liquid from escaping from the compressor. This type of compressor is used in a wide range of applications that require high pressures, such as hoover pumps, air compressors, and refrigeration systems.

The liquid ring compressors market size was USD 874 million in 2020 and is projected to reach USD 1,229 million by 2026; at a CAGR of 5.8% from 2021 to 2026. The increasing global energy consumption is aiding to the growth of the liquid ring compressors market.
