Proven Performance & Reliability

 

NASH liquid ring compressors have the greatest performance range worldwide. Our compressors work on discharge pressures of up to 200 PSIG (15 bar abs.) with a suction capacity of 8,800 CFM (1,500 m³/h) or 9,400 CFM (16,000 m³/h). Thus, compressing gas to 30 PSIG (2 bar abs.) depending on the machine and application.

Advantages Of Liquid Ring Compressors

 

NASH liquid ring compressors require minimal care and low maintenance. Our compressors reduce power and operating costs by handling higher capacities with less energy, and provide the following features and benefits:

Ability to handle carryover resulting in minimal process problems and an increase in uptime; intended for severe applications 
Designed for long life of 40+ years offering the highest reliability 
No internal lubrication required, which means less maintenance and downtime 
No metal-to-metal contact and constant wear-free performance 
Cool running, minimal temperature rise between inlet and discharge; ideal for explosive gases and vapor recovery applications
Only one moving part for simple and reliable operation

 

Low Pressure Liquid Ring Compressors

(Up to 30 PSIG or 2 bar abs.)

Low-pressure liquid ring compressors deliver reliable, proven performance for wastewater treatment, digester gas compression, aeration, and many other applications and industries. With a discharge pressure of up to 30 PSIG (2 bar abs.), Nash provides efficient, low-pressure compressors that require low maintenance. Alternate seal liquids can be used when water is not compatible with the process gas.

Chemical Applications

Inside A NASH Liquid Ring Compressor

The NASH compressor is simple with only one moving part that is a rugged, balanced rotor requiring no internal lubrication. A rotating ring of liquid compressant does what sliding vanes or pistons do in other compressors.

The liquid compressant is represented in the below model by the grid-patterned area. Curved rotor blades, shown in section, transmit power to keep liquid rotating.

The liquid compressant is represented in the below model by the grid-patterned area. Curved rotor blades, shown in this section, transmit power to keep liquid rotating.

The ring of liquid follows the inside of the round-shaped body. Each revolution, every rotor chamber fills with liquid, then partly empties.

While a chamber is going past the inlet port, the liquid moves out. Air or gas is drawn into the chamber. When a chamber arrives at the discharge port, compressed air or gas escapes to the compressor discharge.
