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
- The long design 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 that is ideal for explosive gases and vapor recovery applications
- Only one moving part for simple and reliable operation
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 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.
Highest Standards
Nash is committed to the highest standards in production and safety. We have many ISO certificates, issued to our facilities worldwide and continue to improve our quality by optimizing internal processes.
NASH compressors are certified to ATEX and other global industrial standards.
