Titre de la page produit

Depuis 1947, NASH/GARO conçoit et fabrique des compresseurs à anneau liquide. Principalement utilisée dans les raffineries de pétrole et les sites de production ou dans les usines chimiques et pétrochimiques, cette technologie robuste et fiable permet de traiter les gaz hautement toxiques, explosifs et corrosifs dans les applications. La gamme de compresseurs NASH/GARO, à un ou deux étages, est disponible en acier au carbone, en acier inoxydable, en fonte sphéroïdale, en acier inoxydable duplex et en acier inoxydable super duplex. Des matériaux exotiques tels que l'alliage à haute teneur en nickel ou le titane sont également disponibles sur certains modèles.

Working Principles

Seal liquid is fed into the machine and, by centrifugal acceleration, forms a moving cylindrical ring, which takes the shape of the double lobe eccentric casing.
This liquid ring creates a series of seals in the space between the impeller vanes forming compression chambers.

The gas is fed into the machine by a distribution cone.
Gas compression is achieved by the rotation of the impeller inside the seal liquid.

Features

With their rugged design, NASH/GARO compressors offers optimum performance and low maintenance. They meet design specs while maintaining a simple design and rugged construction. With NASH/GARO Liquid Ring Technology, the effects of erosion, corrosion, vibration and noise are minimized.

• Casing with Double Eccentricity - Allows for perfect balancing of radial forces on the rotor.
• Front Pull Out - Reduced maintenance
• Conical Distribution - The circulation of the seal liquid is by pressure differential - No recirculation pump is required.
• Axial Regulation of the Rotor - Easy check and adjustment of the impeller clearance.
• Tailor Made Design - Optimized efficiency and performance through modifications to the conical distributor, casing and/or impeller.
• Simple Design with Few Mechanical parts.

Advantages

NASH/GARO Overhung Impeller Design provides a unique advantage - Low maintenance and easy service. NASH/GARO compressors require only one mechanical seal, consequently reducing maintenance needs and time.

• Cool running - ideal for handling corrosive gases, vapor recovery and other temperature-sensitive applications
• Near to isothermal compression
• Intrinsically safe
• Low working speed
• Low vibration and noise
• Reduced Maintenance - no internal lubricant required
• Wear-free performance - no metal to metal contact
• Minimal process upset - compressor handles carryovers even in severe applications

Performance

NASH/GARO compressors deliver reliable, proven performance especially for Chemical and Petrochemical process applications. With a discharge pressure up to 13 bar abs., with a suction capacity ranging from 1000 to 2,500 m3/h.
